Arignote or Arignota (/ˌærɪɡˈnoʊtiː, ˌærɪɡˈnoʊtə/; Greek: Ἀριγνώτη, Arignṓtē) was a Pythagorean philosopher from Croton who flourished around the year 500 BC. She was known as a student of Pythagoras and Theano and, according to some traditions, their daughter as well.
According to the Suda, Arignote wrote:
Writings attributed to her were extant in Porphyry's day.
Among the Pythagorean Sacred Discourses (Ἱεροὶ Λόγοι, ΄΄Hieroi Logoi΄΄) there is a dictum attributed to Arignote:
The eternal essence of number is the most providential cause of the whole heaven, earth and the region in between. Likewise it is the root of the continued existence of the gods and daimones, as well as that of divine men.
