Akhenaton was a pharaoh who moved Egypt's capital to a newly-built city in Amarna and attempted to ban worship of the Egyptian Gods in favor of Aten, the sun disk. He was opposed by priests of Amun-Ra, who were believed to have assassinated the pharaoh. After his death, the priests defaced Akhenaton's statues and removed his name from monuments. As punishment for his blasphemy, certain members of Akhenaton's bloodline were cursed to die at a young age by the priests of Amun-Ra. Akhenaton's son, Tutankhamen, was the first to fall victim to this curse, dying at the tender age of nineteen.
Alphonse Gabriel "Al" Capone was an American gangster and businessman who attained notoriety during the Prohibition era as the co-founder and boss of the Chicago Outfit. During this time, his liaison to the African American bootleggers of the area was Josephine, a Greek demigod daughter of Hecate who'd disguised herself as a man to get the work, but eventually left when she was recruited into the Hunters of Artemis. During Apollo and Meg's stop in the Waystation, Leo Valdez mentioned that Josephine (one of its caretakers) had known Capone; Jo herself later explained how she used to work for Capone and other gangsters of the time.
Alfred Joseph Hitchcock was a Greek demigod and is mentioned when Percy Jackson and Will Solace arrive at the Plaza Hotel. The book states that the Plaza attracted a lot of famous demigods over the years, such as the Beatles and Alfred Hitchcock.
Amelia Earhart was a Greek demigod of Zeus and the first mortal woman to fly solo over the Atlantic Ocean. Annabeth Chase mentions her while talking to Circe about her heroes. While Jason Grace, Piper McLean, and Leo Valdez are in Aeolus' fortress, Aeolus mentions that he knocked Amelia Earhart out of the sky and that the gods still pester him about it.
Archimedes was Greek demigod son of Hephaestus and is credited with the creation of many modern machines as well as an accurate approximation of pi. It is the wish among many of Archimedes' modern-day siblings to find the lost works of Archimedes. While searching for Nico di Angelo with Frank Zhang and Hazel Levesque in Rome, Leo Valdez recovered the lost works of Archimedes. He uses them to destroy the eidolons, possessive spirits working for the Earth goddess, Gaea. He planned to take them to Bunker 9 at Camp Half-Blood, to study them further. With Archimedes' works, Leo hoped to save Camp Half-Blood from the Roman forces at Camp Jupiter.
Aten was the physical embodiment of the sun disk, and the favored choice of worship by the pharaoh Akhenaton. He attempted to make Aten the sole deity of Egypt by eradicating worship of the Egyptian gods, but priests of Amun-Ra retaliated by cursing Akhenaton's bloodline.
General Sir Banastre Tarleton was a British soldier and politician and a Roman demigod son of Bellona, best remembered for his military service during the American War of Independence.
Britney Jean Spear is an American singer, songwriter, dancer, and actress. She was mentioned by Apollo when he lists the multiple things he's done in his immortal life, including visiting his wrath upon her at the 2007 MTV Music Video Awards.
Cloacina is the Roman Goddess of the Sewers. Also known as the Purification Goddess. Little is known about her. She has demigod children that attend Camp Jupiter. Apollo mentions her when trying to think of the possible godly parent of Meg McCaffrey. Apollo rementions her while going through a sewer system. Claudia mentions her when thinking of who is behind the incidents at Camp Jupiter.
Coach Wicket was Magnus Chase's 3rd grade PE teacher. He used the word "namby-pamby", but not as a compliment according to Magnus.
Darren Knowles is a Canadian archery instructor. He is the mortal father of Kayla Knowles and a former lover of Apollo. During archery practice at camp, Apollo remembers Darren and mentions him by name when the mortal god is with their daughter, Kayla. Apollo notices the strikingly similar appearances between both Kayla and Darren. Darren Knowles is the only known mortal to have a demigod child with a god of the same gender as himself.
Despoina is the daughter of Poseidon and Demeter, and the twin sister of Arion. Despoina is the Goddess of Winter and Darkness, and is known as "the Mistress" and Monisi. Poseidon once tried to woo Demeter while she was searching for her kidnapped daughter, Persephone. She rejected his advances and transformed herself into a mare to escape him. Transforming into a stallion, the god chased her until she was tired, producing Arion and his sister Despoine as a result. The child was adopted by Anitos, a Titan whose name he chose. Persephone is the beloved daughter, and Despoina was feared for being a shadow goddess related to winter phenomena such as frosts. It was she who took care of nature while her sister was in the world of the dead, thus destroying what Persephone and her mother loved so much, spring and flowers. She also hated her father Poseidon, frozen lakes were signs of her presence in reprisal for her father. She exercised full power over her parents' dominion, but he would rather destroy than strengthen. She was so feared that she was just called "The Mistress".
Despoina has often been said to have the name of Monisi (in classical Greek: Μοναχικός περιφρόνηση, "monos" meaning "only" or "unique" and "fronisi" meaning "winter" or "blizzard", "lonely winter") . Some of the myths report that this was the real name of the goddess, but it was forbidden to be said by her mother, Demeter and only the goddess's followers would have the right to know, which, for many, is only an epithet. Another myth related to Despoina mentions Boreas as her spouse and who thus gave birth, to Crius, who later sat on the same throne as Boreas, being the right messenger between his parents, traveling the world, spreading the Snow along with her surroundings sister Khione.
Eben Norton Horsford was an American scientist best known for his work concerning the reformulation of baking powder. Besides this, Horsford showed great interest in Viking settlements in America and commissioned the statue of Leif Erikson that stands on Commonwealth Avenue in Boston, Massachusetts.
Enyo is the goddess of war, destruction, carnage, and bloodlust. She is the twin sister of Ares, her constant companion in battle. Her Roman equivalent is Bellona. Enyo was born to Zeus and Hera. Her twin brother was Ares. Enyo became responsible for orchestrating the destruction of cities. She would often accompany Ares in battle. During the fall of Troy, Enyo inflicted bloodshed and terror in the war with Eris and her nephews, Phobos and Deimos. Achilles later depicted the aforementioned gods in his shield. Enyo was involved in the war of her half-brother Dionysus and his followers against the Amazons, a battle which Dionysus easily won in India. Unlike most gods, who were very frightened and left, Enyo was so delighted by the war that she refused to choose sides in the battle between Zeus and Typhon. In The Blood of Olympus, Enyo is mentioned by Reyna Ramírez-Arellano, who compares her to her mother Bellona. At Thebes and Orchomenos, the festival Homolôïa was celebrated in honor of Zeus, Demeter, Athena and Enyo. The festival was said to have received the name from Homoloïs, a priestess of Enyo. Her symbol is the swan, but the reason is unknown. Enyo isn't a major Olympian because the Olympians didn't need another war god: Athena and Ares are worshiped more as a deities of war.
Franklin D. Roosevelt, also referred to as F.D.R, was a former president of the United States of America. He was mentioned by Bianca di Angelo when Zoë Nightshade questions her on the identity of the current US president.
George Washington was a demigod son of Athena and former president of the United States of America.
Harriet Tubman was an African-American abolitionist, humanitarian, Union spy during the American Civil War, and a demigod daughter of Hermes. Chiron says Harriet used many clear-sighted mortals on the Underground Railroad, hinting that the Underground Railroad may have utilized the Labyrinth to help transport escaped slaves.
Harry Houdini was a Greek demigod and a famous magician. It is mentioned that he, along with Orpheus and Hercules, had been able to escape from the Underworld. A Nereid said that Houdini "could escape even the depths of Tartarus".
Jackie Chan was a martial artist, actor, stuntman, filmmaker, action choreographer, and singer. He was mentioned by Nico in the The Blood of Olympus.
Jean-François Champollion was a Frenchman who deciphered the hieroglyphics on the Rosetta Stone. In doing so, he fell into a coma for five days and became the first man outside of the House of Life to unleash its magic. This garnered the attention of the First Nome, but Champollion died before he could join the House of Life. The Chief Lector at the time, Iskandar, accepted his descendants instead for training. Champollion is the great uncle of Michel Desjardins, Iskandar's successor as Chief Lector.
Joey Kelso was one of Magnus Chase's classmates in eighth grade biology class. He hid the teacher's frog habitat in the ceiling tiles. A month later, the terrarium crashed down back into the classroom and broke on the teacher's desk. It shattered and sprayed the front row with glass, mold, slime, and rancid frog bodies. Joey Kelso was mentioned by Magnus Chase in The Ship of the Dead.
Joshua Lawrence Chamberlain was a Greek demigod at Camp Half-Blood. He was a Union officer, the governor of Maine, and he commanded the 20th Maine. Chiron mentions him when talking to Percy after having rescued Percy and his friends from the Princess Andromeda.
Libertas is the Roman goddess and personification of freedom, and a very important symbol in the USA. Her Greek counterpart is Eleutheria. Libertas was quite popular during the Roman Republic and Empire, being represented in coins specially after some unpopular or tyrannical figure died (like Julius Caesar or Nero). When the Olympus was placed in New York City (following Western Civilization) and the gods moved with it, Libertas went to this new country and became their new symbol of freedom, taking the place of the previous personification of this concept, Columbia. At some point after 1885 (year when the Statue of Liberty arrived to New York) Libertas decided to inhabit this monument, turning it into a literal, living symbol of freedom. In My Demon Satyr Tea Party, she is mentioned by the goddess Columbia. In exchange for her help, Columbia, still resentful with Libertas, asks Zane to go to the Statue of Liberty next time he's in New York and yell "Columbia rules!", because she knows the Roman goddess hates that which he reluctantly agrees to. In Rome, she was represented as a woman holding a rod and a pileus (a cap that freed slaves used to wear). When she inhabits her statue, she looks like a 151 feet tall copper woman (now in a turquoise color because of the rust). In her left hand, she holds a tablet which has the date of American independence on it, and in her right hand she holds a torch aloft. On her head, she wears a crown with seven spikes - each representing a continent. Libertas presumably possesses the standard powers of a goddess. Columbia, however, claims that Libertas, unlike her, can't fly. As a goddess, Libertas can be in several places at the same time, but according to Sam Greenwood, she spends most of her time "being" her own statue (that would explain her inability to fly).
Lynkos (also known as Lyncus) was once a mortal King of Scythia who got into a fight with Triptolemus and was punished for it by Demeter. Once, Triptolemus came to Scythia to spread the word of farming, he went to the king, Lynkos and he refused to let him spread the word in his kingdom. Triptolemus got angry and there was a fight resulting in the death of the right python of Triptolemus's chariot. Demeter severely punished him for this and turned him into a Lynx. When Frank, Nico and Hazel reach Venice, they encounter Triptolemus where it is mentioned that Lynkos slayed Triptolemus's right python of his chariot and so, he isn't able to spread the word of farming anymore and instead has to resort to online schooling.
Mefitis is the Roman goddess of trash and Noxious Vapors. She is also the mother of Mimi. Mefitis was worshiped by the Samnites, an ancient Italic people who lived in Samnium in south-central Italy before the rise of Rome. Her main shrine was in the volcano Ampsanctus in Samnium, though there are other temples dedicated to her in Cremona and the Esquiline Hill in Rome. It is theorized that Mefitis was originally a goddess of underground sources, such as natural springs, many of these springs were sulfurous which led to her association with noxious gases. She has also been worshiped at Pompeii, so she is almost always identified with volcanoes.
Metis was the Titan goddess of Wisdom and Good Counsel, as well as an Oceanid. She was born from Oceanus and Tethys. According to Percy Jackson's Greek Gods, Metis is smart about advising others. She helped the gods during the First Titan War.
Metis became the first wife of her cousin Zeus. She told him about a prophecy that she would give birth to a daughter and then a son who would be more powerful than him. This posed as a problem for Zeus as Metis was already pregnant with their first child. To prevent the prophecy from taking place, Zeus tricked Metis into taking the form of a fly and swallowed her.
However, Metis took the form of intelligence and gave birth to her daughter Athena, who grew inside her father's head. She taught her daughter how to transform into intelligence. Metis finally faded, becoming a noisy voice in Zeus' head. Her daughter officially became one of the Olympians as the Goddess of Wisdom and Warfare.
Mother William was non-binary and two-spirited person from the Lenape tribe, mentioned by Thomas Jefferson Jr. in The Hammer of Thor. They fought with T.J. in the Civil War, acting as a scout. T.J. mentions they saved everyone from an ambush while heading through Georgia.
Mr. Beauregard is the father of Silena Beauregard and one of Aphrodite's lovers. He owns a chocolate store in the Village, which was how he attracted the goddess' attention. Hoping to cheer his daughter up after the death of her boyfriend, Mr. Beauregard sends Silena a box of bonbons from his chocolate store. She offers one to Percy Jackson during cabin inspection, but upon questioning, Silena claims they taste like "cardboard".
Paris was a prince of Troy, son of King Priam and Queen Hecuba and the younger brother of Hector. He is best known for his elopement with Helen of Troy, queen of Sparta, which served as the catalyst of the Trojan War. Later in the war, he fatally wounds Achilles by shooting him in the heel with an arrow, as foretold by Achilles' mother, Thetis. Just before his birth, his mother dreamed that she gave birth to a flaming torch. This dream was interpreted by the seer Aesacus as a foretelling of the downfall of Troy, and he declared that the child would be the ruin of his homeland. On the day of Paris' birth it was further announced by Aesacus that the child born of a royal Trojan that day would have to be killed to spare the kingdom, being the child that would bring about the prophecy. Though Paris was indeed born before nightfall, he was spared by Priam; Hecuba, too, was unable to kill the child, despite the urging of a priestess of Apollo. Instead, Paris' father prevailed upon his chief shepard, Agelaus, to remove the child and kill him. The herdsman, unable to use a weapon against the infant, left him exposed on the slopes of Mount Ida, hoping he would perish there; he was, however, suckled by a she-bear. Returning after nine days, Agelaus was astonished to find the child still alive, and brought him home in a backpack to rear as his own. He returned to Priam bearing a dog's tongue as evidence of the deed's completion.
Paris is the one who caused the Trojan War to occur with the Trojans fighting against the Greeks. Before the Trojan War began, he was appointed by Zeus to judge the goddesses Hera, Athena, and Aphrodite on was the fairest, thus giving to the winner the golden apple. Each of them promised Paris something, Hera offered him power, Athena offered wisdom, and bravery to be the greatest warrior while Aphrodite offered the most beautiful woman in the world, Helen of Troy. Thus he chose Helen. However, Helen was already married to King Menelaus of Sparta. When Paris eloped, or abducted Helen, Menelaus, in accordance of an oath in which all of Helen's suitors (before she was married) swore before Tyndareus, Helen's father, and King of Sparta, to defend the marriage to the man that Tyndareus will chose for Helen, obligated them to bring her back to Menelaus. Some came voluntarily, like Diomedes while others were forced like Odysseus. These men represented the power, wealth, and military prowess of Achaea. Thus, the whole might of Greece waged war with Troy, which included their generation's greatest heroes like Agammemnon, king of Mycenae (which was the chosen overall commander), Achilles, Diomedes, Odysseus, Philoctetes, and Ajax. In Homer's Iliad, it is said that the Trojan War took ten years of fighting between the Greek armies and the Trojan army. Nine of the ten were spent fighting between the armies but the Greeks didn't have an advantage since Achilles, a son of Thetis, spent his agreement on Agamemnon in his tent. The Tenth, however, had Achilles returning to help the Greek army fight when he heard that Paris' brother, Hector, had killed his best friend, Patroclus, while Patroclus was wearing Achilles' armor. Achilles then killed Hector in a duel around the walls surrounding Troy. After killing Hector, Achilles proceeded to tie Hector's mangled body to his chariot as he drove around the city walls for twelve days, displaying Hector's corpse for all to see. Then, under a short truce, Priam goes to Achilles to ask him to give him the body of Hector's body, so he may hold his funeral. Achilles relents, and gives the dead Hector's body to him, but at the same time he cries. Paris later slays Achilles as the latter is storming the walls of Troy - he shoots an arrow, guided by Apollo, into the hero's heel, killing him. Paris himself is later slain by Philoktetes, using the poisoned-tipped arrows of Hercules.
The Judgement of Paris was the cause for the result of the Trojan War to start between the Greeks and the Trojans. Paris was picked by Zeus, the king of the gods, to decide who was the fairest goddess on Olympus - Aphrodite, Hera, or Athena.
There are many reasons on how Paris judged who was the true fairest goddess. One was that all three goddesses went naked to show him their beauty so he could decide which of them were fairest. The second was that at the same time all three goddesses stood before him they told him that if he decided on one of them they would give him:
- Athena - the wisdom, and skills in battle to become the greatest warrior.
- Aphrodite - the most beautiful woman on earth (which turned out to be Helen)
- Hera - ownership of Europe and Asia.
Paris, however, thought that each of Athena and Hera's gifts to him were not so good because he knew that his father and the city of Troy were at peace and that there was no use of a war. So instead of picking Athena and Hera as the fairest of all, Paris picked Aphrodite because he thought her gift was the best. This made Hera and Athena deeply angered that Paris had not picked them and they angrily disappeared to Olympus, causing the rest of the gods to help each side of the war in the fight against and for Troy, with Hera and Athena choosing to fight against Paris and Troy, and Aphrodite to fight for him.
Percy Jackson briefly mentions Paris and his relationship with Helen when talking to Aphrodite about tragic love stories in a white limousine at the Junkyard of the Gods, to which the love goddess replies to by shaking her head sadly, but having a smile as she is nodding.
Phoebe is the Titaness of Mystery. She is the sister-wife of Koios and mother of Leto and Asteria. She was the fourth girl. She lived on Delphi. She was one of the first people to figure out how to hear the voices of Delphi. According to Percy Jackson's Greek Gods, she wasn't a gloomy, mysterious sort of fortune-teller and always looked on the positive side of things. Her prophecies tended to be only good stuff. After Phoebe and Koios got married, they only saw each other once in a while since they lived very far apart.
Priests of Amun-Ra
The priests of Amun-Ra opposed the pharaoh Akhenaton when he attempted to outlaw worship of the Egyptian gods. They were believed to have assassinated him and were responsible for cursing members of Akhenaton's bloodline to die at a young age. Bes hated the priests because they were, according to him, full of themselves.
They created the Book of Ra and hid its three sections hoping that a worthy magician would one day find it and reawaken Ra. Vladimir Menshikov, former leader of the Eighteenth Nome in Russia, is a descendant of the priests.
Ravana was the main antagonist of Ramayana, one of the major Sanskrit epics of ancient India. Ravana was born to Ravana and Kaikesi; his siblings were Kumbhakarna, Khara and Dushana and Surpanakha (born Meenakshi). He and Kumbhakarna were the second reincarnations of Jaya and Vijaya, Vishnu's gatekeepers. At some point in his life, he overthrew his half-brother, Kubera, as king of Lanka, the city of gold. He killed Vidyutjihva, Surpanakha's greedy husband out of self-defense, causing his sister to search the world. After Surpanakha came back to him, Ravana found out that she was humiliated by Vishnu's current incarnation, Rama, his brother Laxmana and his wife Sita. So he had a rakshasa named Maricha distract Rama and Laxmana while being disguised as a golden deer while he kidnapped Sita, who was staying in a fancy ashram, himself while disguised as a hermit and took her to Lanka. An old vulture named Jatayu tried to rescue her, but Ravana cut his wing off which killed him.
Soon after Ravana arrived home, Hanuman arrived and tried to save her, but Sita refused help unless it was from Rama. This made Hanuman mad and have a tantrum and, unfortunately, the noise attracted Ravana who took the monkey demigod prisoner. Ravana tried to kill him by setting his tail on fire, but Hanuman managed to make his tail grow and escape, setting fire to the city of Lanka. Later, Rama with the help of the monkey king Sugreeva, attacked Lanka and killed Ravana.
Ravana is depicted as having ten heads. Although not mentioned by name until the glossary, Ravana was mentioned by Aru Shah when she remembered that Valmiki wrote Ramayana. Ravana is often said to be an example of a dark lord or evil overlord. He is a powerful king of Lanka. He is very powerful with god-like powers. He has many henchman.
Sethlans is the Etruscan god of artisans. He faded away like most of the other Etruscan gods. In Un Natale Mezzosangue, Sethlans is mentioned to have left a gold bracelet made of tiny keys in the care of Charu.
Tethys is the Titaness of the Seas, Freshwater and nursing mother. She is the sister-wife of Oceanus and the mother of the Oceanids and Potami. Tethys was the third girl. According to Percy Jackson's Greek Gods, she loved rivers, springs, and fresh water of any kind. She was very kind, always offered her sibling something to drink, though the others got tired of hearing that the average Titan needs twenty-four large glasses of water a day to stay hydrated. She thought of herself as a nursemaid for the whole world, since all living things need to drink.
Theia is the Titaness of Clear Sight, Splendor and Enlightenment. She is the sister-wife of Hyperion and mother of Helios, Selene and Eos. According to Percy Jackson's Greek Gods, she was the oldest of the elder Titanesses. She loved sparkly things and bright scenic views. Every morning she would dance with happiness when daylight returned. She would climb mountains just so she could see for miles around. She would even delve underground and bring out precious gems with her magic powers to make them gleam and sparkle. She was the one that gave gold its luster and made diamonds glitter.
Themis is the Titaness of Divine Law, Justice and Fairness. She was the second daughter of Gaea and Ouranos. She realized from an early age that she had a natural sense of right and wrong. She understood what was fair and what wasn't, forming the first laws in the world. Whenever she was in doubt, she claimed she could draw wisdom from the earth.
According to Percy Jackson's Greek Gods, Themis was wise, thoughtful, quiet, modest, and tried not to draw attention to herself, always wearing a simple shawl over her hair. She had a good reputation with her brothers and sister, mediating even the worst arguments. Themis wasn't interested in marriage, but became Zeus' second wife as none other Titaness besides Metis (who was swallowed by him) wanted to marry him. Through Zeus, Themis became the mother of the Horai. In some myths, she became the mother of the Fates, whose power scared their parents, to the point they decided to divorce in fear of conceiving more powerful children.
Thomas Faynor was a Greek demigod son of Hephaestus. He was the owner of the bakery in London where the Great Fire of London began in the year 1666. He is mentioned to be the last child of Hephaestus to have power over fire before Leo Valdez.
Thomas Jefferson was the third president of the United States and the principal author of the Declaration of Independence. Annabeth Chase stated that he is a member of the Judgment Pavilion in the Underworld.
Thomas Young was an Englishman who proved that the Rosetta Stone's three languages all conveyed the same message.
Tutankhamen, famously known as King Tut, was the son of Egyptian pharaoh Akhenaton. He died at the age of nineteen due to a curse placed on his father's bloodline by priests of Amun-Ra. Because the nature of the curse was not known to them, modern doctors have ascribed various reasons to Tutankhamen's death, including poison and genetic disease.
Walt Stone's father
William Shakespeare was an English poet, playwright, and actor. Annabeth mentions that he was one of the rotating judges for the Judgment Pavilion in the Underworld. Even though Shakespeare was a Greek demigod, he has received a gift of poetry from Norse god Odin.
William Sherman was a Greek demigod and a son of Ares. He was a Union general during the American Civil War. Gleeson Hedge mentions him to Frank Zhang when he mistakes the latter for a son of Ares.
