Using scant but precious ancient literary documentation, the archaeological finds and the iconography of the figurative products that reproduce roofs, the book traces the gradual evolution process of the roof carpentry that led to such an invention. New hypotheses are advanced on the technical achievements of the main Mediterranean civilizations – Egyptian, Minoan and Mycenaean, Phrygian, Etruscan, Greek and Roman – in a broad and ambitious excursion that crosses the whole of Antiquity. The book is accompanied by a rich illustrative apparatus that includes historical and original photographs as well as numerous explanatory drawings.
