High Renaissance
As far as the end of the High Renaissance is concerned Hartt, Frommel, Piper, Wundrum, and Winkelman all state that the High Renaissance ended in 1520 with the death of Raphael. Honour and Fleming stated the High Renaissance was the first quarter of the 16th century meaning it would have ended in 1525. By contrast, Luigi Lanzi, in his "History of Italian Painting", 1795–96, stated it ended with the Sack of Rome in 1527, when several artists were killed and many other dispersed from Rome, and Stokstad agrees. Raunch asserts that 1530 has been considered to be the end of the High Renaissance. Hartt adds that 1520 to 1530 was a transition period between the High Renaissance and Mannerism. Traditionally, the end of the High Renaissance in Florence is seen as marked by the end of the Republic of Florence and the beginning of the Duchy of Florence in 1532.
