THE NEADES were gigantic animals native to the island of Samos whose roar could split the earth.
The legend may have arisen from dinosaur fossils found on the island.
Aelian, On Animals 17. 28 (trans. Scholfield) (Greek natural history C2nd A.D.) :
"Euphorion says in his Commentaries [C3rd B.C.] that in primeval times Samos was uninhabited, for there appeared in the island animals of gigantic size, which were savage and dangerous to man to approach, and they were called Neades. Now these animals with their mere roar split the ground. So there is a proverbial saying current in Samos, ‘He roars louder than the Neades.’ And the same writer asserts that huge bones are displayed even to this day."
