This suite of plates examines closely the eighteenth-century method of calculating the pressure required to produce a fountain with a certain height of water column. The plates demonstrate the complicated process of measuring the altitudes and gradients at which the water would fall through the pipes laid, and the hydromechanics involved in devising a water container of the right shape and size. A further plate displays some popular fountain garden layouts.
The plates are accompanied by a series of important and extensive articles on fountains. The first of these, and the most substantial, is by D'Alembert. Co-editor of the Encyclopédie, he had already distinguished himself as a mathematician, mechanician, and physicist. D'Alembert's formula was named after him, and one field which he had a great influence in was fluid mechanics. Here he expertly tackles the difficult topic of fountains and their creation, examining the mathematics and physics involved.
Following articles include Fontaines Artificielles by Antoine-Joseph Desallier D'Argenville, who wrote around six hundred articles for the project, mostly on gardening, Diderot's Fontaine Domestiques, and Jacques-François Blondel's description of fountains and their role in architecture. In all, this set of articles includes contributions by some of the most distinguished of the many Encyclopédists.
