The Beatus of Liébana, Codex of Ferdinand I and Doña Sancha, is also known as Facundus Beatus, and is "the most beautiful and complete of all the Beatus manuscripts" (Henri Stierling) and the only one commissioned by a King.
The Codex was made for the King and Queen of Castille and León and later sent to the collegiate Church of San Isidoro. It was requisitioned by Philip V during the War of Spanish Succession and sent to the Royal Library.
The Codex was created in the 11th century (in 1047) with the text written in a Visigothic script.
