Crates of Mallus in Wikipedia

Crates, of Mallus in Cilicia (modern day Southeastern Anatolia Region, Turkey), was a Greek language grammarian and Stoic philosopher of the 2nd century BC, leader of the literary school and head of the library of Pergamum. His chief work was a critical and exegetical commentary on Homer. He is also famous for constructing the earliest known globe of the Earth. Life He was born in Mallus in Cilicia, and was brought up at Tarsus, and then moved to Pergamon, and there lived under the patronage of Eumenes II, and Attalus II. He was the founder of the Pergamon school of grammar, and seems to have been at one time the head of the library of Pergamon. Among his followers were Hermias (Κρατήτειος Ἑρμείας mentioned in sch. Hom. Il. 16.207a), Zenodotus of Mallus and Herodicus of Babylon. He visited Rome as ambassador of either Eumenes, in 168 BC, or Attalus in 159 BC. Having broken his leg and been compelled to stay there for some time, he delivered lectures which gave the first impulse to the study of grammar and criticism among the Romans.[1] Works Crates made a strong distinction between criticism and grammar, the latter of which he regarded as subordinate to the former. A critic, according to Crates, should investigate everything which could throw light upon literature; the grammarian was only to apply the rules of language to clear up the meaning of particular passages, and to settle the text, prosody, accentuation, etc. From this part of his system, Crates derived the surname of Kritikos. Like Aristarchus of Samothrace, Crates gave the greatest attention to the works of Homer, from his labours upon which he was also surnamed Homerikos. He wrote a commentary on the Iliad and Odyssey in nine books. Some fragments of this commentary are preserved by the scholiasts and other ancient writers. His principles were opposed to those of Aristarchus, who was the leader of the Alexandrian school. Crates was the chief representative of the allegorical theory of exegesis, and maintained that Homer intended to express scientific or philosophical truths in the form of poetry. Besides his work on Homer, Crates wrote commentaries on the Theogony of Hesiod, on Euripides, on Aristophanes, and probably on other ancient authors; a work on the Attic dialect; and works on geography, natural history, and agriculture, of all of which only a few fragments exist[2]. The Globe of Crates According to Strabo, Crates devised a globe representing the Earth, which is thus the earliest known globe representing the Earth: We have now traced on a spherical surface the area in which we say the inhabited world is situated; and the man who would most closely approximate the truth by constructed figures must necessarily take for the earth a globe like that of Crates, and lay off on it the quadrilateral, and within the quadrilateral put down the map of the inhabited world. But since the need of a large globe, so that the section in question (being a small fraction of the globe) may be large enough to receive distinctly the appropriate parts of the inhabited world and to present the proper appearance to observers, it is better for him to construct a globe of adequate size, if he can do so; and let it be no less than ten feet in diameter.[3]
