The Eleusinian Mysteries were initiations held every year for the cult of Demeter and Persephone based at the Panhellenic Sanctuary of Eleusis in ancient Greece.

In Greek mythology when Demeter was searching for her daughter Persephone, who had been abducted by Hades, she decided to rest from her weary quest at Eleusis. The daughters of the king, Celeus, offered to help the goddess who was disguised as an old woman.

Recuperating in the royal palace, Demeter took a shine to Celeus' infant son Demophon (or Triptolemus) to whom she gave ambrosia and, each night in secret, she held the youth over a fire to make him immortal. Demophon's mother happened to see this one night and, misunderstanding the goddess' intentions, banished the old woman from the palace.

Not best pleased, Demeter revealed her true identity and ordered Celeus to build her a temple. This was done, and the goddess retreated inside it and brought a terrible drought and famine upon the land, until the other Olympian gods revealed where Persephone was and agreed to release her from the underworld for half of the year. In thanks to Eleusis, the goddess blessed the land and taught the people sacred rites so that the Eleusinians might thereafter prosper both morally and physically. And so the Eleusinian Mysteries were born.

The Mysteries represented the myth of the abduction of Persephone from her mother Demeter by the king of the underworld Hades, in a cycle with three phases: the descent (loss), the search, and the ascent, with the main theme being the ascent (ἄνοδος) of Persephone and the reunion with her mother.

A feeling of mystery is evoked here, on my Luthieros recreated ancient Greek kithara (the large wooden lyre played only by the professional musicians of classical antiquity) in my own variation of an exotic Middle Eastern mode.
