Casiodoro de Reina (1520-1594) is known for
his translation of the Bible into Spanish. He is considered one of the most significant figures in the history of the Spanish Protestant movement. His work, published in 1569, is known as the
Reina-Valera Bible, which became the standard Spanish translation for Protestant churches.
While he was a prolific writer, his most important work was undoubtedly the Reina-Valera Bible. It is a cornerstone of Spanish Protestantism and has had a profound impact on the language and culture of Spain and Latin America.
