Nautical charts identified an island called "Bracile" west of Ireland in the Atlantic Ocean as far back as 1325, in a portolan chart by Angelino Dulcert. Later it appeared as Insula de Brasil in the Venetian map of Andrea Bianco (1436), attached to one of the larger islands of a group of islands in the Atlantic. This was identified for a time with the modern island of Terceira in the Azores, where a volcanic mount at the bay of its main town, Angra do Heroismo, is still named Monte Brasil.
