(Cuenca, España, 1505 - Nápoles, Italia, 1541)
"Juan de Valdés (Cuenca, 1509 - Nápoles, 1541), fue un humanista, erasmista y escritor protestante español."
"Juan de Valdés (c.1500 - August 1541) was a Spanish religious writer. He was the younger of twin sons of Fernando de Valdés, hereditary regidor of Cuenca in Castile, where Valdés was born. He has been confused with his twin brother Alfonso (a courtier of Charles V, Holy Roman Emperor, who attended Charles's coronation in Aachen in 1520 and was Latin secretary of state from 1524). Alfonso died in 1532 at Vienna."
