The year-by-year annals kept in the monasteries and courts of Rus’ and Muscovy, which record, among wars and portents, the founding of towns, the building of walls and churches, and the fires that repeatedly destroyed them.
The Moscow chronicles of the later fifteenth century are the main written source for the rebuilding of the Kremlin under Ivan III. They tell how the new Dormition cathedral collapsed in 1474, how the Bolognese engineer Aristotele Fioravanti was brought to rebuild it, and how he was sent first to Vladimir to study the cathedral there, which was to be his model; and they record the brick walls and towers raised by Italian masters from 1485 and the great fires of the 1490s.
