At the age of about fourteen Leonardo was apprenticed by his father to the artist Andrea del Verrocchio. Leonardo was eventually to become a paid employee of Verrocchio's studio. During his time there, Leonardo met many of the most important artists to work in Florence in the late fifteenth century including Sandro Botticelli, Domenico Ghirlandaio and Pietro Perugino. Leonardo helped Verrocchio paint "The Baptism of Christ", completed around 1475. According to Vasari, Verrocchio, on seeing the beauty of the angel that his young pupil had painted, never painted again.
