Lasinio, later the influential curator of the Camposanto in Pisa, learned the method of colour printing based on the three primary colours plus black from Edouard Gautier Dagoty, whose father had been granted the patent for J.C. Le Blon’s process after the latter’s death. Lasinio undertook the mammoth task of engraving the collection of painters’ self-portraits in the Vasari Corridor in Florence. He completed some 338 prints, which it has been estimated would have required over a thousand colour plates.
