Copying, sketching or making studies from old masters is a common way for art students and artists to learn how to draw and paint. A tour description at the Museum of Fine Arts Houston says, "Artists in subsequent generations looked back to the work of Titian and others by visiting museums and making sketches of their work to learn the art of painting. This tour of Old Master paintings in the MFAH collection from the Renaissance through the 18th century explores how future artists would learn the skills of drawing, coloration, and composition from the artists who came before them." (See "Members Tour: Learning from the Old Masters".)
