Deipnosophistae

Now, as a long discussion had taken place about fish, it was plain that Cynulcus was annoyed at it; and so the excel- lent Democritus, anticipating him, said—But, O you men fish, as Archippus says, you have omitted (for I too must throw in a little contribution of my own) those which are called fossil fishes, which are produced at Heraclea, and near Tium, in Pontus, which is a colony of the Milesians, though Theophrastus gives us an account of them. And this very same philosopher has also told us about those that are congealed in ice the whole winter, so that they have no feeling whatever, and make not the slightest motion, until they are put into the saucepans and boiled. And these fish have this especial peculiarity, which also belongs in some degree to the fish which are called fossil fish in Paphlagonia. For it is said that ditches are dug in those places to an exceeding depth, where no overflow of rivers ever reaches, nor of any other waters whatever; and yet in those ditches there are found living fishes.
