Leonardo da Vinci spent ten years learning in a workshop before anyone called him a master.
In fifteenth-century Florence, a bottega was a workshop where young apprentices learned art, architecture, and engineering by working alongside a master on commissioned projects. The apprentice was not a student in the modern sense. From the first day, the apprentice contributed to real work, grinding pigments, preparing panels, transferring drawings, and eventually painting secondary figures.1
Andrea del Verrocchio's bottega in Florence was among the most renowned. Leonardo da Vinci entered Verrocchio's workshop around 1466, at roughly fourteen years of age, and remained for about a decade.2
Other alumni of Verrocchio's bottega included Sandro Botticelli, Pietro Perugino, and Lorenzo di Credi. The workshop produced paintings, sculptures, metalwork, and engineering designs simultaneously. Apprentices learned multiple disciplines because the bottega did not separate them.1
The master's reputation depended on the quality of the workshop's output, not on individual attribution. Many works credited to a single artist were collaborative productions involving apprentices at various stages of development.
The bottega system operated on implicit contracts. A master provided training, materials, and room and board. An apprentice provided labor and, in many cases, a fee paid by the apprentice's family. The arrangement typically lasted between six and twelve years, depending on the trade.3
The Florentine bottega represents an approach to professional development that the modern education system largely abandoned: learning through participation in real work, under the direct mentorship of a practitioner, over an extended period. The model produced some of the most versatile practitioners in Western history during a period when the separation between learning and doing had not yet been conceived.
