Hernán Núñez de Toledo y Guzmán (Valladolid, 1475 - Salamanca, 1553) was a Spanish humanist, classicist, philologist, and paremiographer. He was called el Comendador Griego, el Pinciano (from Pintia, the Latin name of Valladolid) or Fredenandus Nunius Pincianus. He earned his degree in 1490 from the Spanish College of San Clemente in Bologna. He returned to Spain in 1498 and served as a preceptor to the Mendoza family, in Granada. In this city, he studied classical languages as well as Hebrew and Arabic. Cardinal Gonzalo Ximénez de Cisneros hired him as censor of the cardinal’s press at Alcalá de Henares. There, Nuñez worked on the Complutensian Polyglot Bible, specifically on the Septuagint. Nuñez was named professor of rhetoric at the Universidad Complutense, which had recently been founded. He then taught Greek from 1519. During the Castilian War of the Communities, Nuñez sided with the comuneros but avoided execution. He then taught at the University of Salamanca, occupying the post once filled by Antonio de Nebrija. At the age of 50, he retired from teaching to dedicate himself fully to research, although he seems to have still given classes on Hebrew at the University of Salamanca.
