Two Prophets, in initials S and V
, 1392–99, Purchased by Pierpont Morgan, 1910
, MS M.478.16, 17
The initial S (of Salus) begins the Introit to the Mass for the nineteenth Sunday after Pentecost, while the V (of Venite) begins the Introit for Easter Wednesday. The fragmentary texts on the backs of the cuttings were sufficient to identify the Introits.
