Perrin retrata la proeza del extraordinario anciano que levanta una catedral con sus propias manos.

Blaise Perrin (Fontaine-les-Dijon, 1982) is a French photographer who, during a stay in Madrid, was mesmerised by Justo Gallego's work. The latter accepted Perrin's help in exchange for allowing him to photograph the cathedral, and the photographer started sweeping, carrying bricks, mixing cement and assembling scaffoldings during long working hours on the old man's command-and taking pictures during the brief moments of rest.
