A 16th century miniature map of Terceira

A scarce map of Terceira, engraved by Pieter van den Keere for the 'Caert-Thresoor', with a text by an unknown author. By 1600 this map was being published in the 'Tabularum Geographicarum Contractarum' with a text by Petrus Bertius, and in 1616 a new plate was engraved by Jodocus Hondius II, slightly larger and with wider borders with scales of longitude and latitude.
