VII. As it happened, they were connected, being second cousins; for Aethra was the daughter of Pittheus, and Alkmena the daughter of Lysidike, and Lysidike and Pittheus were brother and sister, being the children of Pelops and Hippodameia. So Theseus thought that it would be a great and unbearable disgrace to him that his cousin should go everywhere and clear the sea and land of the brigands who infested them, and he should refuse to undertake the adventures that came in his way; throwing discredit upon his reputed father by a pusillanimous flight by sea, and upon his real father by bringing him only the sandals and an unfleshed sword, and not proving his noble birth by the evidence of some brave deed accomplished by him. In this spirit he set out on his journey, with the intention of doing wrong to no one, but of avenging himself on any one who offered wrong to him. VIII. And first in Epidaurus he slew Periphetes, who used a club as his weapon, and on this account was called the club-bearer, because he laid hands upon him and forbade him to proceed farther on his way. The club took his fancy, and he adopted it as a weapon, and always used it, just as Herakles used his lion's skin; for the skin was a proof of how huge a beast the wearer had overcome, while the club, invincible in the hands of Theseus, had yet been worsted when used against him. At the Isthmus he destroyed Sinis the Pine-bender by the very device by which he had slain so many people, and that too without having ever practised the art, proving that true valour is better than practice and training. Sinis had a daughter, a tall and beautiful girl, named Perigoune. When her father fell she ran and hid herself. Theseus sought her everywhere, but she fled into a place where wild asparagus grew thick, and with a simple child-like faith besought the plants to conceal her, as if they could understand her words, promising that if they did so she never would destroy or burn them. However, when Theseus called to her, pledging himself to take care of her and do her no hurt, she came out, and afterwards bore Theseus a son, named Melanippus. She afterwards was given by Theseus in marriage to Deïoneus, the son of Eurytus of Oechalia. Ioxus, a son of Melanippus, and Theseus's grandchild, took part in Ornytus's settlement in Caria; and for this reason the descendants of Ioxus have a family custom not to burn the asparagus plant, but to reverence and worship it.
