the preceding section of the poem had dealt at some length with the extended family of porthaon's sister demodice, tracing her line down to the generation following the trojan war. here "ē' hoiai" (plural) is used to jump backwards in order to complete the account of the descendants of porthaon and demodice's father agenor by covering the son's family. elsewhere the formula is used in transitions to more distant branches. the ehoie of mestra, for example, ultimately serves to reintroduce the family of sisyphus, mestra's great-granduncle who hoped to win her as bride for his son glaucus. although that marriage does not take place, the descendants of sisyphus are soon presented.
