S Uciredor

Rodericus (or S Uciredor) was a French composer of the 14th century.

Nothing is known of Rodericus's life, although it has been suggested that he is Rodrigo de la Guitarra, since Rodrigo is the only known contemporaneous musician with the same name. He is known through a single ballade attributed to him in the Chantilly Codex as S Uciredor, which is "Rodericus" spelled backwards. The piece, Angelorum Psalat, is in two voices and is an exemplary work of the Ars subtilior style, similar to that of Jacob Senleches. Angelorum Psalat exhibits considerable rhythmic complexity and its text employs contrasting imagery of original sin and the harmony of the spheres, a common poetic device of the age.
