PORTRAIT OF THE DOLPHIN LOUIS XV (1710-1774), c. 1712 Pierre Gobert (1662-1744) and workshop, French school. Louis XV was born on February 15, 1710, the third son of the Duke of Burgundy and Maria Adelaide of Savoy. The couple's first two children, both named Luís, died prematurely between April 1711 and March 1712. Consequently, this third Luís succeeded his great-grandfather, the Sun King, in 1715.
