Pausanias Description of Greece 8.14.9

[9]
  As you go down from the acropolis of Pheneus you come to a stadium, and on a hill stands a tomb of Iphicles, the brother of Heracles and the father of Iolaus. Iolaus, according to the Greek account, shared most of the labours of Heracles, but his father Iphicles, in the first battle fought by Heracles against the Eleans and Augeas, was wounded by the sons of Actor, who were called after their mother Moline. In a fainting condition he was carried by his relatives to Pheneus, where he was carefully nursed by Buphagus, a citizen of Pheneus, and by his wife Promne, who also buried him when he died of his wound.
