The foundation medal for the suburban church of Santa Maria dell' Assunzione in Ariccia, commissioned from the architect Gian Lorenzo Bernini by Pope Alexander VII, and completed in 1665. Like many foundation medals, it records the formative rather than the final stage of the building's design. The medal, which was ready by 28 January 1662, pre-dates by at least a year the decision to frame the round church with loggie. An entry in the diary of Alexander VII (13 December 1661) documents Bernini's responsibility for the design of the commemorative medal.
