Angelo Ambrogini, commonly known by his nickname, anglicized as Politian, Italian Poliziano [politˈtsjano], Latin Politianus (from his birthplace, Montepulciano, Latin Mons Politianus) (14 July 1454 – 24 September 1494) was an Italian Renaissance classical scholar and poet, one of the revivers of Humanist Latin. He used his didactic poem Manto, written in the 1480s, as an introduction to his lectures on Virgil.

Politian was born as Angelo Ambrogini in Montepulciano, in central Tuscany in 1454; he is known in literary annals as Angelo Poliziano or Politianus, from his birthplace. His father, Benedetto, a jurist of good family and distinguished ability, was murdered by political antagonists for adopting the cause of Piero de' Medici in Montepulciano; this circumstance gave his eldest son, Angelo, a claim on the House of Medici.

At the age of 10, after the premature death of his father, Politian began his studies at Florence, as the guest of a cousin. There he learned the classical languages of Latin and Greek. From Marsilio Ficino he learned the rudiments of philosophy. At 13 he began to circulate Latin letters; at 17 he wrote essays in Greek versification; and at 18 he published an edition of Catullus. In 1470 he won the title of homericus adulescens by translating books II-V of the Iliad into Latin hexameters. Lorenzo de' Medici, who was then the autocrat of Florence and the chief patron of learning in Italy, took Politian into his household, made him the tutor of his children, and secured him a distinguished post in the University of Florence. He was also one of the scholars at the Platonic Academy under the leadership of Marsilio Ficino, at the Careggi Villa.
