Casiodoro de Reina or de Reyna ( 1520 – 15 March 1594) was a Spanish theologian who (perhaps with several others) translated the Bible into Spanish. Early life Reina was born about 1520 in Montemolín in the Province of Badajoz. From his youth onward, he studied the Bible. In 1557, he was a monk of the Hieronymite Monastery of St. Isidore of the Fields, outside Seville (Monasterio Jerónimo de San Isidoro del Campo de Sevilla). Around then, he had contact with Lutheranism and he became an adherent of the Protestant Reformation. He fled with about a dozen other monks when they came under suspicion by the Spanish Inquisition for Protestant tendencies to Geneva But he was not comfortable with the atmosphere and the doctrinaire rigidity around John Calvin. In 1558, Reina declared that Geneva had become "a new Rome" and left. Reina travelled in 1559 to London, where he served as a pastor to Spanish Protestant refugees. However King Philip II of Spain was exerting pressure for his extradition. In exile on the Continent In the late 1550s he was suspected by the Spanish inquisitors in Seville to have been the one who converted the monks of San Isidro to Lutheranism. in April 1562, the Inquisition made an auto-da-fé in which an effigy of him was burned. The works of Reina and his colleagues were placed in the Index of prohibited books and he was declared a "heresiarch" (leader of heretics). About 1563 Reina went on to Antwerp, where he became associated with the authors of the Polyglot Bible. In April 1564 he went to Frankfurt, where he settled with his family. Reina wrote the first great book against the Inquisition: Sanctae Inquisitionis hispanicae artes aliquot detectae, ac palam traductae ("Some arts of Holy Inquisition"). This work was printed in 1567 in Heidelberg under the pseudonym: Reginaldus Gonsalvius Montanus. He secretly translated the work of the critic of Calvin, Sebastian Castellion, De haereticis, an sint persequendi ("Concerning heretics, whether they should be Persecuted"), that condemned executions "for reasons of conscience" and documented the original Christian rejection of the practice. Biblical translation While in exile, variously in London, Antwerp, Frankfurt, Orléans and Bergerac, funded by various sources (such as Juan Pérez de Pineda) Reina began translating the Bible into Spanish by using a number of works as source texts. For the Old Testament, the work appears to have made extensive use
