Venerable Adrian of Poshekhonye (died 1550) was a Russian Orthodox monk and iconographer, who was the founder and first igumen (abbot) of the Dormition monastery in Poshekhonye, north Yaroslavl region.
In Rome, he painted frescoes in the Pinelli chapel of Santa Maria in Vallicella, including Scenes from the life of the Virgin and Birth of Jesus on the arches, and the Dormition, Coronation, and Funeral of the Madonna on the vault.
The congregation also continued to be active outside Germany, in among other places Belgium, Austria, Portugal, Brazil and Japan; in 1906 the abbey of the Dormition (or Assumption) (now Hagia Maria Sion Abbey) in Jerusalem was founded.
A mosaic reredos was added in the apse, which was manufactured by Salviati and is loosely based on Giotto's Dormition.
In many places, blue is used for the Dormition Fast (except from the Transfiguration to its afterfeast (August 6-13), when either gold or white is used).

These ambitious Kremlin cathedrals (among them the Dormition and Archangel Cathedrals) were imitated throughout Russia during the 16th century, with new edifices tending to be larger and more ornate than their predecessors (for example, the Hodegetria Cathedral of Novodevichy Convent from the 1520s).
