His works were very numerous; but of these, only fragments have been preserved. They appear to have related principally to moral subjects, and, accordingly,
Horace classes him with
Chrysippus as a moral philosopher, and speaks of him in a manner which proves that the writings of Crantor were much read and generally known in
Rome at that time. He also made some attempts at poetry; and
Diogenes Laërtius relates, that, after sealing up a collection of his poems, he deposited them in the temple of
Athena in his native city, Soli. He is accordingly called by the poet
Theaetetus, in an epitaph which he composed upon him, the friend of the
Muses; and that his chief favorites among the poets were
Homer and
Euripides.
On Grief The most popular of Crantor's works in Rome seems to have been that "On Grief" (, ), which was addressed to his friend Hippocles on the death of his son, and from which
Cicero seems to have heavily relied upon in his
Tusculan Disputations. According to Cicero, the
Stoic philosopher
Panaetius called it a "golden" work, which deserved to be learnt by heart word for word. Cicero also made great use of it while writing his celebrated
Consolatio on the death of his daughter,
Tullia. Several extracts from it are preserved in
Pseudo-Plutarch's treatise on Consolation addressed to Apollonius, which has come down to us. Crantor paid special attention to
ethics, and arranged "good" things in the following order - virtue, health, pleasure, riches.
Commentaries on Plato Diogenes Laërtius says that Crantor left behind 30,000 lines of Commentaries (ύπομνήματα), but of these only fragments have been preserved. Crantor seems to have been the first member of the
Platonic academy to write
commentaries on the works of Plato;
Proclus credits Crantor with the first commentary on the
Timaeus, and
Eudorus of Alexandria makes use of Crantor's work in his own commentary, which is in turn preserved by
Plutarch. ==Notes==
