Samuel Gacon is associated with the Hebrew press that produced the Faro Pentateuch, completed on 30 June 1487 and widely regarded as the first known book printed in Portugal. Institutional and scholarly accounts place this workshop in Faro’s Jewish quarter, in the area now corresponding to Praça D. Afonso III. Surviving evidence also links the Faro Hebrew press to at least two other works, a Babylonian Talmud and a divorce tract, showing that this was not an isolated experiment but part of a short-lived Jewish printing activity in late fifteenth-century Faro.

The site itself is lost. Later urban and conventual development overwrote the medieval Jewish quarter, and institutional guides identify the former Convent of Nossa Senhora da Assunção, now the Municipal Museum of Faro, as standing on the site of the old judiaria. For that reason, this pin should be understood as an approximate historical location tied to the memory of Samuel Gacon and the Faro Pentateuch, not as a surviving print shop building. The only known surviving copy of the Faro Pentateuch is held in the British Library.
