For most of its early history in the Western tradition, drawing did not stand on its own. Through antiquity and the Middle Ages drawing played an instrumental, subordinate role, feeding into other, larger projects rather than standing as finished work in itself. A monastic scribe might draw to plan an illuminated initial; a workshop might draw to plan a mosaic, a mural, or the design of a sculpted figure for a Gothic church. In every one of these settings, the drawing was a means to an end, a tool consumed in the making of something else, rarely preserved or valued for its own sake. That changed toward the end of the fourteenth century, in the workshops of northern Italy. Drawing began to be practiced and kept as an independent artistic document rather than a disposable working tool. The shift did not happen all at once. Early sketchbooks, among them those associated with Giovannino de Grassi, Antonio Pisanello and Jacopo Bellini, still leaned on standardized workshop models even as they opened space for individual observation and copying from antique sources. By the middle of the fifteenth century, the drawings coming out of different regions and different hands had begun to diverge noticeably, each carrying the mark of a particular artist's personality rather than a shared formula. The clearest evidence that drawing had become its own art form arrived with the generation of Leonardo da Vinci, Raphael and Michelangelo. Michelangelo's sheets produced what is often called the first connoisseur drawings, drawings collected and esteemed as personal documents in their own right rather than as by-products of a painting or sculpture commission. North of the Alps, Albrecht Durer is credited as the artist who most forcefully championed the autonomy of drawing, joined by artists such as Altdorfer and Huber, whose landscape studies carried an emotional feeling for nature well before Romanticism existed as a named movement. By the time Mannerism took hold across Italy, roughly 1525 to 1600, drawing had settled into the role it has held since, valued equally as an artist's private working method and as a public, collectible statement in its own right.
