Crinitus, Italian scholar and academic (b. 1475)
Pietro Crinito (22 May 1474 – 5 July 1507), known as Crinitus, or Pietro Del Riccio Baldi (derived from Riccio, 'curly', translated into Latin as crinitus), was a Florentine humanist scholar and poet who was a disciple of Poliziano.

He is best known for his 1504 commonplace book, De honesta disciplina. This has been taken to be a source for the work of Nostradamus.
