Heavy bodies toward the earth's center, with circle figures

Every heavy body drives toward the center

Above one of the earth figures Leonardo writes that every heavy body pushes toward the center so much that it destroys itself. It captures his idea of gravity as an irresistible drive of weight toward the world's center.

Weight and counterweight across hemispheres

The long left-hand passage argues that the center of any heavy body corresponds to the center of the gravity placed in the opposite hemisphere. The opposite ends of the earth's diametral line make opposite motions when they act as centers of weight and counterweight in opposite hemispheres, so that moving the weight above moves the counterweight below.

Inscribed figures and the square remainder

The sheet is filled with circles carrying inscribed squares, diagonal crosses and hexagons, part of the ongoing quadrature and lune studies. A brief note by the third figure from the left records that the remainder is a square.
