“Although a plethora of volumes about Leonardo da Vinci exists, Innocenzi’s work is unique in focusing on Leonardo’s scientific and technical treatises, drawings, and notes, placing them in context with other thinkers working during the Renaissance or before. … The accessible style and many illustrations should make Innocenzi's text attractive and useful for general readers and undergraduate students.” (A. C. Prendergast, Choice, Vol. 56 (5), January 2019)
