E-Bbc 586 (No. 09)
Anglès, Johannis Pujol. Opera omnia, vol. 1, p. xix, erroneously attributed this piece to Joan Pau Pujol, indicating it with a question mark. Marvin, Palestrina. A Guide to Research, does not include E-Bbc 586 nor E-Boc 11bis as manuscript sources for this motet by Palestrina. Apart from these two Barcelona manuscripts, there is only one additional manuscript source that contains this motet: the manuscript MS 2760 (olim O. IV.174) from the Biblioteca Casanatense. According to Marvin MS 2760 is a manuscript copied in the 19th century in score format who belonged to Giuseppe Baini. According to Marvin, the manuscript contains unknown or doubtful works by Palestrina.
