Eurytus was a disciple of Philolaus, and Diogenes Laërtius[3] mentions him among the teachers of Plato, though this statement is very doubtful.
Through a dubious commentary to Aristotle's Metaphysics a caricatural image of Eurytus has gained wide currency.
A mediaeval writer confused with Alexander of Aphrodisias presented Eurytos as a kind of mosaic-setter who delineated various shapes with some definite number of pebbles.
[5] Taking in account specific mathematical usage he suggested an emended translation of the original passage from Aristotle's work (Metaphysics 1092b9-13): Are [numbers explanatory or causal] in the sense of definitions, as points are of magnitudes?
[7]According to the historian's from the Stanford Encyclopedia of Philosophy, Philolaus and Eurytus are identified by Aristoxenus as teachers of the last generation of Pythagoreans (D. L. VIII 46).
