Pulley mechanism, solids, and candlesticks (transmitted light)
Two-wheel pulley with a hung weight, polyhedra, stemmed vessels and a hand study
A transmitted-light exposure of the opening at ff. 282v-283r, in which the drawings and writing on both faces of each leaf show through and overlap. The left sheet carries a pulley arrangement of two wheels from which a small weight hangs, marked with letter labels including d and f, together with a large curved form that reads as a hand and forearm; the right sheet is crowded with pyramids, prisms and other geometric solids, a row of stemmed candlesticks or footed vessels, and scattered numbers. Because no transcription is supplied for this variant, the extensive notes across both pages remain untranscribed here and are recorded only as visual evidence.

Two-wheel pulley carrying a suspended weight
On the left sheet a support holds two adjacent wheels over which a line runs down to a small hanging block. Letter labels including d and f mark points of the mechanism, and a short note runs beside it. The arrangement reads as a study of a pulley or hoist raising or balancing a weight.
Pyramids, prisms and other solids
The right sheet is filled with small perspective drawings of geometric solids, among them triangular pyramids, wedges and prisms, several shown from more than one angle. Numbers such as 100 are written beside some of them. They appear to accompany a study of volumes or proportional figures.
Row of stemmed candlesticks or vessels
Along the top of the right sheet stands a row of tall stemmed objects that read as candlesticks, candelabra or footed vessels, each with a broad foot and a knopped stem. They are drawn in outline as designed objects rather than as working mechanisms.
Large study of a hand and forearm
The lower half of the left sheet is occupied by a large curved form that reads as a hand with curled fingers joined to a forearm, overlaid by wavy contour lines. Because this is a transmitted-light image, the shape is partly confused with drawings on the other face of the leaf.
