Extraordinary Jubilee at the start of Alexander VII’s papacy (1655)
Alexander VII, who was Pope from 1655 to 1667, never celebrated an ordinary universal Jubilee; he did, however, celebrate five extraordinary jubilees to mark special occasions. Adopting the practice begun by Sixtus V, this included a Jubilee at the start of his pontificate, as depicted in this engraving. Note that the iconographic representation here is inaccurate, given that for this type of Jubilee the ceremony used for Holy Years was never adopted, and the door was not opened (as shown in the second frame from the top, on the left)
