Raphael
By the end of 1508, Raphael had moved to Rome, where he lived for the rest of his life. He was invited by the new Pope Julius II, perhaps at the suggestion of his architect Donato Bramante, then engaged on St. Peter's Basilica, who came from just outside Urbino and was distantly related to Raphael. Unlike Michelangelo, who had been kept lingering in Rome for several months after his first summons, Raphael was immediately commissioned by Julius to fresco what was intended to become the Pope's private library at the Vatican Palace. This was a much larger and more important commission than any he had received before; he had only painted one altarpiece in Florence itself. Several other artists and their teams of assistants were already at work on different rooms, many painting over recently completed paintings commissioned by Julius's loathed predecessor, Alexander VI, whose contributions, and arms, Julius was determined to efface from the palace. Michelangelo, meanwhile, had been commissioned to paint the Sistine Chapel ceiling.
Raphael Levi Hannover
Raphael Levi Hannover (1685 – May 17, 1779) was a German mathematician and astronomer. The son of Jacob Joseph, Hannover was born at Weikersheim, Franconia in 1685. He was educated at the Jewish school of Hanover and at the yeshivah of Frankfurt am Main, and became bookkeeper in the firm of Simon Wolf Oppenheimer in Hanover. Here he attracted the attention of Leibniz, and for a number of years was one of his most distinguished pupils (including last secretary), and afterward teacher of mathematics, astronomy, and natural philosophy. He also corresponded with Moses Mendelssohn.
