Pausanias Description of Greece 1.44.8

[8] Then it was that she [= Ino] fled to the sea and precipitated [ aphiénai] herself and her son from the Rock [ Petrā] that is Molouris. The son, they say, was brought to land on the Isthmus of Corinth by a dolphin, and honors [ tīmai] were given to Melikertes, thereafter renamed Palaimon. One of these honors, in-compensation-for [ epi + dative case] him, was the celebrating [ agein] of the competition [ agōn] called the Isthmia. The Rock [ Petrā] that is Molouris has been considered to be sacred [ hierā] to the White Goddess [ Leukotheā] and Palaimon. But the other rocks, as one travels further, are customarily-thought [ nomizein] to be polluted [ en-ageis], in that Skīrōn [= ‘he of the White Rock’], dwelling there [ par-oikeîn], used to cast into the sea all the strangers [ xenoi] he met. A turtle used to swim under the rocks [ petrai] to seize those that fell in. Sea turtles are like land turtles except for their size and for the shape of their feet, which are like those of seals. Retribution [ dikē] for these things overtook Skīrōn, for he was precipitated [ aphiénai] into the same sea by Theseus.
