Perry's Index to the Aesopica
Perry reserves 433 for an aetiological account of a cult of Aphrodite
established by a sailor who had been warned by Aphrodite to take a load
of water and go sailing; he was able to sell the water to thirsty merchants
who had been becalmed at sea and were thirsty. The anecdote comes from
Plutarch's Aetia Graeca, 54 (303a).
You can find a compilation of Perry's index to the Aesopica in the gigantic appendix to his
edition of Babrius and Phaedrus for the Loeb Classical Library
(Harvard University Press: Cambridge, 1965). This book is an absolute must for anyone interested
in the Aesopic fable tradition. Invaluable.
