The window has four
roundels that read from bottom to top: the Dormition (not shown), the
carrying of Mary's bier to Gethsemane or Jehoshaphat, the empty tomb,
and the Coronation of the Virgin. The Assumption is shown between the
third and fourth roundels: two angels lifting Mary to
Heaven in a mandorla.
In the center of the
empty-tomb scene one of the apostles seems to be swinging a censer, presumably to signify the
performance of a liturgical ritual. A censer is sometimes also seen in Dormition icons in
the East (example) and from time to
time in the West (example).
