Narrative
Demophon (or Acamas), son of Theseus, returning from Troy, was hosted in Thrace by Phyllis, daughter of a Thracian king (Lycurgus or other names in variants). They betrothed; he sailed on to settle affairs at Athens (or Cyprus), promising to return by a set day. He delayed. Phyllis went nine times to the shore in despair, then hanged herself (or died of grief); the gods transformed her into an almond tree (or she was buried and an almond grew from her grave). When Demophon at last returned and embraced the trunk, it put forth leaves—sign that she forgave or still answered him.
Apollodorus keeps a brief Greek handbook notice; Ovid’s *Heroides* 2 elaborates Phyllis’s letter of reproach (**Roman**). Catalogue the Thracian love-death and tree aetiology as a Theseid nostos distinct from Eleusinian Demophon.
