SOURCE: Vitruvius. De Architectura (Como, 1521), ed. Cesare Cesariano, Liber decimus, p. CLXV NOTES: This 1521 edition of Cesare Cesariano's translation and commentary on Vitruvius's treatise entitled 'De Architectura' (Ten Books on Architecture) is the first edition of the treatise not in Latin. Vitruvius's original, unillustrated treatise was written during the first century BC. The woodcut illustrations in this edition, most probably drawn by Cesariano, are largely based on the cuts in the 1511 edition of Vitruvius edited by Giovanni Giocondo.
