(Ἵππασος), a Lacedaemonian who is mentioned by Diogenes Laertius (8.84) as the author of a work on the Lacedaemonian republic in five books, from which a statement is quoted by Athenaeus (i. p. 14). The time at which he lived is unknown. [L.S]
(Ἵππασος), of Metapontum or Croton (Iamblich. Vit. Pyth, 18. §§ 81, 88. 23.104), is mentioned both by Iamblichus and by Diogenes Laertius (8.84) among the elder Pythagoreans.
Hippasus is said to have been the founder of a school or sect of the Pythagoreans, called the Acusmatici (ἀκουσματικοί), in opposition to the Mathematici. Aristotle (Aristot. Met. 1.3) speaks of Hippasus as holding the element of fire to be the cause of all things: and Sextus Empiricus (ad Phys. 1.361) contrasts him with the Pythagoreans in this respect, that he believed the ἀρχή to be material, whereas they thought it was incorporeal, namely, number. A single sentence quoted by Diogenes Laertius as expressing one of his doctrines seems to mean that he held all things to be in motion and change, but according to a fixed law. (Iamblich. Ibid. §§ 81, 88; Villoison, Anecd. Graec. ii. p. 216.) In consequence of his making known the sphere, consisting of twelve pentagons, which was regarded by the Pythagoreans as a secret, he is said to have perished in the sea as an impious man. Works
According to one statement, Hippasus left no writings (D. L. 8.84), according to another he was the author of the μυστικὸς λόγος, written to calumniate Pythagoras. Further Information

(Ἵππασος). A native of Metapontum and follower of the Pythagorean doctrine. He is said to have excelled in the application of mathematical principles to music, statics, and mensuration. In common with others of the same school, he held that fire was the originating cause of all things. He taught also that the universe is finite, is always changing, and undergoes a periodical conflagration. In consequence of his having made known the sphere consisting of twelve pentagons, which was a secret of the Pythagoreans, he is said to have been drowned as an impious person (Diog. Laert.viii.).
