MACEY 1989 proposed an extended and partially reordered cycle, including Josquin’s “little” Ave Maria and his Tu lumen, tu splendor patris. Elders discusses the hypothesis in the critical notes to the edition of the work in NJE (CC) 25.
SCHMIDT 2017, 31 underlines that the three concordances of this cycle transmit it following Compère's cycle C44 In nomine Iesu / Officium de cruce, also linked to the Holy Week. According to him, the two cycles are stylistically similar and Compère's authorship of the cycle Popule meus has to be considered seriously.
Only the motet Ave virgo gloriosa Maria mater gratiae is clearly attributed to Compère in a concordant source (I-Rvat CS 46). For the attribution of the Sanctus see M281.
According to WARD 1986, 506, Sanctus and Ave virgo gloriosa Maria mater gratiae are parts of a five-pieces cycle, whose components are dispersed in the four Libroni. In WARD’s hypothetical cycle, however, the motet O genitrix gloriosaM292 is placed between the Sanctus and Ave virgo gloriosa Maria mater gratiae.
