- Admiral to King Pedro and King Fernando of Portugal.
- Son of the Genoese Manuel Pessanha, originally Emanuele Pessagno, appointed admiral by King Dinis of Portugal (c.1320).
- Admiral of the Portuguese fleet in charge of defending Lisbon when Enrique II of Castile invades Portugal for the second time (1373). He was accused of being a very poor leader, and acting cowardly avoiding attacking the Castilian fleet at a time when his own ships had the advantage over the enemy. As a consequence he loses his post of Admiral, which is given to João Afonso Telo, Queen Leonor's brother. [Fernando, ch. 74: 66-71]
