Crantor

for he says that a certain Elysius of Terina, when he was grievously mourning the death of his son, came to a place of consulting the dead, asking what had been the cause of so great a calamity;

And not absurdly did Crantor — who was among the very foremost noble men in our Academy — say:

Nature brings the pain, to which indeed your Crantor, they say, thinks one must yield;

But Speusippus and Xenocrates, who were the first to take up Plato's method and authority, and after them Polemo and Crates, and together with them Crantor, gathered in the Academy, diligently maintained what they had received from their predecessors.

We have all read the book of Crantor, the Old Academic, on grief;

Hearers of Polemo were Crates and Crantor, in whom the Old Academy from Plato came to an end.
