Laboring side by side, Michelangelo and his assistants developed an easygoing camaraderie, especially during those periods when the master was engaged in the type of large-scale sculptural projects that he most enjoyed. “Almost half of his workforce had some sort of pet name: the Stick, the Basket, the Little Liar, the Dolt, Oddball, Fats, Thorny, Knobby, Lefty, Stumpy, and Gloomy,’’ Wallace notes. “Because he was his own bookkeeper, Michelangelo recorded their names, number of days worked, and the wage of every employee every week. Having grown up in the stoneworking town of Settignano, Michelangelo was personally acquainted with most of his assistants; he was familiar with their talents and employed their fathers, cousins, and neighbors. Such familiarity was a form of quality control and provided an unusual degree of labor stability.”
