a Greek philosopher of the Old Academy, was born, probably about the middle of the 4th century B.C., at Soli in Cilicia. He was a fellow-pupil of Polemo in the school of Xenocrates at Athens, and was the first commentator on Plato. He is said to have written some poems which he sealed up and deposited in the temple of Athens at Soli (Diog. Laertius iv. 5.25). Of his celebrated work On Grief (Hepi 7r v00us), a letter of condolence to his friend Hippocles on the death of his children, numerous extracts have been preserved in Plutarch's Consolatio ad Apollonium and in the De consolatione of Cicero, who speaks of it (Acad. ii. 44.1 35) in the highest terms (aureolus et ad verbum ediscendus). Crantor paid especial attention to ethics, and arranged "good" things in the following order - virtue, health, pleasure, riches.
