Aristaeus (or Aristaios) is the god of cheesemakers, beekeepers, and rural crafts.
The nymphs taught Aristaeus beekeeping, cheese making and many other crafts. He decided to pass on his knowledge and skills to humanity.
Tale of Orpheus
Aristaeaus tried to get the romantic attention of the nymph Eurydice, but she got married to the musician Orpheus. Aristaeaus followed her into a forest during her honeymoon and ran while asking her to marry him. This caused that Eurydice to run away and accidentally get bitten by a snake. Aristaeaus didn't want to accept the blame so he ran away.
Aristaeaus married Autonoe, daughter of the hero and King Cadmus of Thebes. They had two children: a son named Actaeon and a daughter named Macris.
