The Assumption of the Virgin
Oil and gold on wood
Metropolitan Museum of Art
The angels form a mandorla as they lift the Virgin. The crowning (by angels, rather than by Christ) and the arrival in Heaven are simultaneous. The twelve apostles are shown without attributes, but the two in the foreground seem to be John (left, with just the beginning of a moustache and goatee, not a beard like the others) and Peter (balding from the crown).
Angels singing in Heaven from a shared songbook were a common device in the previous century. See this page for more examples.
