Ἀρχύτας

Of Taras,¹ son of Hestiaios or Mnesarchos or Mnasagetes or Mnasagoras; Pythagorean philosopher. This man saved Plato from being murdered by the tyrant Dionysios.² He championed the [Greek-]Italian federation, and was chosen general with full powers by his fellow-citizens and the [other] Greeks of the region. At the same time he taught philosophy and had celebrated pupils and wrote many books. [It is said that] this man was plainly a teacher of Empedocles.³
And [there is] a proverb: Archytas' rattle;⁴ [coined] because Archytas invented the rattle, which is a kind of instrument producing sound and noise.⁵
"He made a bronze rattle and rattled it".⁶
