This autograph paper manuscript, composed of 136 leaves and written in Latin, documents thirty years of Taccola's activities. The predominant themes and problems are civil and military engineering, the analysis of techniques and instruments to measure heights and distances and studies of hydraulic devices (siphons, pumps and mills, sometimes tidally-powered), as well as a series of quotations from ancient authors (especially Philo, Vegetius and Frontinus).
