Pausanias Description of Greece 1.42.7

[7]
  On the road to the Town-hall is the shrine of the heroine Ino, about which is a fencing of stones, and beside it grow olives. The Megarians are the only Greeks who say that the corpse of Ino was cast up on their coast, that Cleso and Tauropolis, the daughters of Cleson, son of Lelex , found and buried it, and they say that among them first was she named Leucothea, and that every year they offer her sacrifice.

[7] On the road to the Prytaneion [‘City Hall’] [of Megara] is the hero-shrine [ hērōion] of Ino, around which is a fencing [ thrinkos] of stones. Olive trees grow there. The people of Megara are the only Greeks [ Hellēnes] who say that the corpse [ nekros] of Ino had washed ashore on their coast; more, they say that Klēsō and Tauropolis, the daughters of Klēsōn son of Lelex, found and buried it; even more, they say that it was in their locale [= Megara] that Ino was for the first time named White Goddess [ Leukotheā], and every year a sacrificial-feast [ thusiā] is celebrated [ agein] in her honor.
