Crantor in Harpers Dictionary of Classical Antiquities

（Κράντωρ). A philosopher of Soli, among the pupils of Xenocrates, B.C. 300. He was the first who wrote commentaries on the works of Plato. Crantor was highly celebrated for the purity of his moral doctrine, as may be inferred from the praises bestowed by the ancients upon him. From one of his works, Περὶ Πένθους, Cicero drew largely in writing the third book of the Tusculanae, and the lost treatise De Consolatione on the death of his daughter Tullia. Cf. Cic. Acad. ii. 44.
