Greek mythology always connected with Demeter of the Eleusinian Mysteries, might be accounted the son of King Celeus of Eleusis in Attica, or, according to the Pseudo-Apollodorus (Bibliotheca I.V.2), the son of Gaia and Okeanos—another way of saying he was "primordial man".
While Demeter was searching for her daughter, having taken the form of an old woman called Doso, she received a hospitable welcome from Celeus. He asked her to nurse Demophon—"killer of men", a counterpart to Triptolemus— and Triptolemus, his sons by Metanira. As a gift to Celeus, because of his hospitality, Demeter planned to make Demophon immortal by burning away his mortal spirit in the family hearth every night. She was unable to complete the ritual because Metanira walked in on her one night. Instead, Demeter chose to teach Triptolemus the art of agriculture and, from him, the rest of Greece learned to plant and reap crops. He flew across the land on a winged chariot while Demeter and Persephone cared for him, and helped him complete his mission of educating the whole of Greece in the art of agriculture.
When Triptolemus taught Lyncus, King of the Scythians, the arts of agriculture, Lyncus refused to teach it to his people and then tried to kill Triptolemus. Demeter turned him into a lynx. Triptolemus was equally associated with the bestowal of hope for the afterlife associated with the expansion of the Eleusinian Mysteries (Kerenyi 1967 p 123).
In the archaic Homeric Hymn to Demeter, Triptolemus was briefly mentioned as one of the original priests of Demeter, one of the first men to learn the secret rites and mysteries of Eleusinian Mysteries: Diocles, Eumolpos, Celeus and Polyxeinus were the others mentioned of the first priests. The role of Triptolemus in the Eleusinian mysteries was exactly defined: "he had a cult of his own, apart from the Mysteries. One entered his temple on the way to the closed-off sacred precinct, before coming to the former Hekataion, the temple of Artemis outside the great Propylaia." (Kerenyi). In the 5th-century bas-relief in the National Museum, Athens, which probably came from his temple, the boy Triptolemus stands between the Two Goddesses Demeter and the Kore, and receives from Demeter the ear of grain (of gold, now lost).
Porphyry (On Abstinence IV.22) ascribes to Triptolemus three commandments for a simple, pious life: "Honor your parents", "Honor the gods with fruits"—for the Greeks, "fruits" would include the grain—and "Spare the animals" (Kerenyi, p128).
Triptolemus is also depicted as a young man with a branch or diadem placed in his hair, usually sitting on his winged chariot, adorned with serpents. His attributes include a plate of grain, a pair of wheat or barley ears and a scepter.
Celeus or the peasant Dysaules may be substituted for Triptolemus as the primordial Eleusinian recipient of the first gifts of the Mysteries.
