The artists that produced the codex have not been conclusively established. It was previously incorrectly and anachronistically attributed to Francisco de Holanda,[3] although his father António de Holanda, then a young man, is not outside the realm of possibility.[1] More recent scholarship attributes part of the codex to calligrapher and music scribe Martin Bourgeois, based on the inscription "hinc Burgos" found within one of the litterae cadassae, and on stylistic similarities to the c. 1504-06 Choirbook of Philip the Fair and Juana of Castile (Royal Library of Belgium, MS 9126), which has been attributed to him.[1]
