Hyacinthus

"Seek the caverns, near the springs of blue. Oh, Apollo.....your sanity will be taken away, but do not....."

- Hyacinthus to Apollo / Lester Papadopulous in The Hidden Oracle

Hyacinthus, also known as Hyacinth, was a demigod son of Pierus of Magnesia, a human and Clio, the Muse of History. Hyacinthus is a spartan prince who was loved by both Apollo and Zephyros.

History
At some points, Apollo stumble on Hyacinthus and fell in love with him. Apollo goes all head over heels for him. Unfortunately, Apollo isn't the only one who notice Hyacinthus and our lad actually has another guy who is callled Zephyros. Zephyros has no idea how to express his feelings properly and ends up stewing in his own jealousy.

While playing a game of quoits with Apollo, Hyacinthus was accidentally killed by a jealous Zephyros. In his grief, Apollo refused to allow Hades to take Hyacinthus. He transformed the mortal into a flower, which became known as the hyacinth that bears his name. As a display of penitence, Zephyros was forced into the service of the god of love, Eros.

The House of Hades
While trying to retrieve Diocletian's scepter, Jason Grace and Nico di Angelo meet with Zephyros, still in the service of Eros. Zephyros, in his Roman aspect Favonius, provides an explanation as to why he serves the god of love. He recounts the story of Hyacinthus. He tells about the jealousy he had felt for Apollo and Hyacinth's closeness. Jason is initially surprised by Favonius's falling in love with a man, but he recovers quickly.

The Hidden Oracle
When Nosoi (plague spirits) attack Apollo on his way to Camp Half-Blood, he gets flashbacks of the events that occurred on the day Hyacinthus died.

Apollo also confesses that Hyacinthus and Daphne are his greatest and favorite lovers. Apollo tells that he is reminded of the few months he spent with Hyacinthus when he sees his son Will Solace with his boyfriend Nico di Angelo. After his meeting with Rhea, Apollo falls into a dream where Hyacinthus appears as a ghost, talks to him for a very brief time and asks him to find the caverns near the blue springs. When Hyacinthus starts fading away from the dream, Apollo desperately reaches and grabs his lover's shoulder and begs him not to leave him. But he wakes up, holding a pot of hyacinth flowers, and later comes to know he was talking to the flowers.

When Apollo sings to tackle the Myrmekes, he sings of his love for Hyacinthus and expresses his regret over his jealousy which ultimately killed Hyacinthus. He also tells that he created the hyacinth flowers out of his dead lover's blood, to always keep him in the sunlight.

Apollo continuously grieves for the loss of Hyacinthus, as he is constantly reminded of him everywhere he goes while in human form.

The Dark Prophecy
When Apollo meets Meg McCaffrey again, he says that he had never been so happy to see anyone, including Hyacinthus in his amazing tuxedo on their date night.

The Burning Maze
When Apollo, Meg and Grover Underwood solve puzzles to get to Herophile, one clue is ''Named for Apollo’s fallen love, this flower should be planted in autumn. Set the bulb in the soil with the pointy end up. Cover with soil And water thoroughly ... you are transplanting''. Apollo got reminded of Hyacinthus so runs down the eight squared corridor. But they actually had to fill in the ... to make the word unless, as a result the trio nearly gets burned by the essence of Helios.

Appearance
Hyacinthus is described by Apollo to be quite handsome. Apollo names him as the most handsome among the men he has met. According to Apollo, Hyacinthus had copper or bronze skin, curly black hair and eyes as purple as senatorial robes. He had a kind and brilliant smile in Apollo's flashbacks. In Apollo's dream, however, he is seen to have an ugly dent above his left ear, where the discus had struck him.

Apollo
At some points , Apollo fell in love with the handsome mortal man Hyacinthus. One day, Zephyros, the god of the west wind, who was also smitten by Hyacinthus, came across him and Apollo playing a game of quoits. Jealous that Hyacinthus preferred the radiant archery god to him, Zephyros shifted the wind and sent a heavy metal ring flung by Apollo right at Hyacinthus’s head, instantly killing the youth. The devastated Apollo would turn his lover's deceased body into a flower, the hyacinth. In order to avoid Apollo's wrath, Zephyros would seek protection from Cupid who had mercy on him because he was driven crazy by love, who forced the guilt-ridden wind god to work for him forever as a result. As mentioned in The Hidden Oracle, Hyacinthus would forever remain one of Apollo's two all-time favorite lovers (on par with Daphne).

Zephyros
At some point, Zephyros fell in love with a mortal man named Hyacinthus, who he found "quite extraordinary." After finding Hyacinthus with Apollo, playing a game of quoits, Zephyros accidentally killed Hyacinthus in a jealous rage. As the mortal died, Apollo transformed him into a flower, a hyacinth. Aphrodite's immortal son Eros offered Zephyros protection, on the condition that he would work with him forever.

Pierus of Magnesia
Because Pierus of Magnesia is the king of Magnesia, Hyacinthus is a noble himself. Pierus love Hyacinthus dearly and take care of Hyacinthus very well. When Hyacinthus was a teenager, Pierus taught Hyacinthus martial arts and archery.

Clio
Because Clio is the Muse of history, Hyacinthus is very fond of history. Clio love Hyacinthus dearly and take care of Hyacinthus very well. When Hyacinthus was a teenager, Clio taught Hyacinthus history to make sure Hyacinthus don't make the same mistake as the ancestor.
