Cychreides

Accounts preserved in summary form present several variant origins. In one strand a drakōn/serpent terrorizes the island of Salamis and is slain by the local hero Cychreus, an action that is woven into his foundation or kingship legend. In another, Cychreus is said to have raised the serpent as a pet; the animal later rampages and is driven off or captured by a man named Eurylochus, who gives it to Demeter, and the goddess thereafter keeps it. A third variant applies the epithet 'the dragon' to Cychreus himself for his violent temper, a metaphorical rather than literal serpent narrative; in that version he is received by Demeter at Eleusis and made her priest. These divergent accounts are preserved in summaries of ancient sources (traditionally attributed to authors such as Apollodorus, Strabo, and entries preserved by later compilers).

Ancient summaries consistently classify Cychreides as a drakōn or serpent (Greek descriptions translate as 'dragon' or 'serpent'), but no detailed physical features survive in the consulted summaries: there is no preserved authoritative description of color, precise size, number of heads, or other anatomical particulars. In one cult‑linked motif the creature is one of a pair of serpent‑dragons associated with Demeter's chariot, a role that situates it among the class of large, reptilian mythic beings known in Greek tradition.

The sources do not ascribe specific supernatural powers (such as magical breath or shape‑changing) to Cychreides beyond its characterization as a dangerous drakōn/serpent that can terrorize a community. Its reported behaviours vary by tradition: actively terrorizing Salamis in some accounts; being domesticated or kept by Cychreus and later rampaging; being captured or driven away by human agents and given to Demeter; and functioning, in cultic variants, as part of Demeter's retinue (pulling her chariot). The narratives emphasize its monstrous, threatening aspect and its ambiguous relation to human and divine spheres rather than enumerating discrete magical abilities.
