Beato of Liébana wrote three works: "Commentary on the Apocalypse", the longest and most widely known due to its use in the illumination of manuscripts; "Apologetics", in which he opposes the 'adoptionism' of Elipando (Medieval heresy that resolves the mystery of the Holy Trinity and, according to which, Christ as a man was the father's adopted son); and the hymn "O Dei Verbum", where for the first time news is given of the Spanish evangelization carried out by the apostle Saint James, who is referred to as the patron saint of Spain. The Beato de Fernando I y Sancha is a facsimile of Codice B.N. Madrid Vit. 14-2, one of the many illuminated manuscripts of the Beatus “ Commentary. ” the manuscript dating from about 1074 is also known as "Facundus' Beatus." It is, according to Henri Stierling, "the most beautiful and complete of all the Beatus manuscripts” and the only one commissioned by a King. It was made for the King and Queen of Castille and León. The text written is in a Visigothic script. The codex was bound by Juan Francisco Menoyre in 1720.
