Small figures whirl most; deep-sinking things obey the eddies least

Smaller figures are whirled more than large ones

Of things carried by water, the one of smaller figure has the greater whirling, because the great revolutions of eddies are rare in the courses of rivers while the small eddies are almost innumerable. Large things are whirled only by great eddies, but small things are turned about by both small and great.

The deeper a thing sinks, the fewer whirls act on it

Of objects equal in length and breadth, those that sink deeper have fewer revolutions, for the whirls vary greatly from the surface to the bottom. A deep-sinking thing is beset by many differing heights of revolution and so remains in doubt, often obeying none, or if it obeys, obeying only the most powerful.

Marginal note: deeper objects obey the water least

A note in the margin restates the rule: of things equal in figure and quantity, the one that sinks deeper obeys the revolutions of the water the less.

Arched supports and a brick staircase

At the upper left a red-chalk drawing, partly gone over in pen, shows arched supports, captioned together with a brick staircase (scala di mattoni).
