For the "Credo in E minor, RV 591", Vivaldi borrows some material he composed for his "Magnificat", which places it later - probably after 1727. This completely choral work has much in common stylistically with the very famous "Gloria" (RV 589) and with his earlier psalm setting "In exitu Israel" (RV 604). Clayton Westermann's 1970 edition, with an English translation beneath the Latin text, is reprinted here in a digitally-enhanced, easy-to-read format.
