Scala Dei (Stair of God), also called Tractat de contemplació (Contemplation treatise), is a literary work written by Francesc Eiximenis possibly in 1399 in Valencia in Catalan and dedicated to Maria de Luna, queen of the Crown of Aragon and wife of king Martin of Aragon. Origin Some parts of the Llibre de les dones (Book of Women), specifically the ones included in the Treaty of penance and the Treatise of contemplation, were included later in the book that Eiximenis probably offered to queen Maria de Luna when his husband Martin of Aragon (and she also) was crowned, as Andreu Ivars pointed out. We know the king's coronation took place on 13 April 1399, and the one of the queen on 23 April 1399. Content Thus the book that is known as Scala Dei (Stair of God), would consist in parts of the above-mentioned Llibre de les dones. Together with the parts of this work that are literally transcribed, chapters 101 to 274 (that deal with theological virtues, cardinal virtues, the ten commandments, the seven deadly sins and the senses) are summarized, as scholar Curt Wittlin showed. This book belongs to the genre of prayer books, which had a lot of success during the late Middle Ages and specially among the upper classes.
