The story of Tobias and the angel Raphael are from The Book of Tobit which is a book of scripture that is part of the Catholic and Orthodox biblical canons. It was recognized as canonical by the Council of Hippo (in 393), the Councils of Carthage of 397 and 417, and the Council of Florence (in 1442), and confirmed in the Counter-Reformation by the Council of Trent (1546).
Tiziano Vecelli or Vecellio (c. 1488/90 – 27 August 1576), known in English as Titian (/ˈtɪʃən/ TISH-ən), was a Venetian painter during the Renaissance, considered the most important member of the 16th-century Venetian school. He was born in Pieve di Cadore, near Belluno. Titian was one of the most versatile of Italian painters, equally adept with portraits, landscape backgrounds, and mythological and religious subjects. His painting methods, particularly in the application and use of color, exercised a profound influence not only on painters of the late Italian Renaissance, but on future generations of Western art.
