GIACOMO da Teramo. - Canonist, also called de Ancharao, born in 1350, died in Poland in 1417. After studying law in Padua, he was probably also a professor in that city. In 1391 he was consecrated bishop of Monopoli, then transferred to the sees of Taranto (1400), Florence (1401), and Spoleto (1410). Under Martin V he served as apostolic legate in Poland.
His most famous work is the *Processus Luciferi contra Iesum*, also called *Compendium perbreve consolatio peccatorum nuncupatum et apud nonnullos Belial vocationum* (Augsburg 1472), a kind of novel written in the form of a legal proceeding, inspired by a similar work attributed to Bartolo, the *Processus Satanae*.
