CONSOBRINO (SOBRINHO), JOÃO. – Carmelite theologian, born in Lisbon at the beginning of the 15th century, died there on 11 January 1486 (not in 1475, as others suppose). Having completed his studies at the University of Oxford and obtained degrees in theology and canon law (2 July 1449), he acquired, owing to his exceptional learning, the title of magister maximus.
Upon returning to his homeland, he was preacher and counsellor to King Alfonso V of Portugal, and also inquisitor. Subsequently elected superior of the Portuguese province (1479), he governed it until his death, which occurred as a result of poison administered to him by the Jews. He left an excellent treatise: De iustitia commutativa et arte campestoria ac alarum ludo (Paris 1496), as well as some other theological works.
