Gonçalo de Sintra

Gonçalo de Sintra or de Cintra (d.1444/45), was a 15th-century Portuguese explorer and servant of Prince Henry the Navigator.

According to chronicler Zurara, Gonçalo de Sintra was a young squire (escudeiro) or stirrup boy in the household of Portuguese prince Henry the Navigator, Duke of Viseu. Others have characterized Sintra as older, an illustrious knight (cavaleiro), distinguished for his military service at Ceuta (although it is possible these were two different men with the same name).
