Red-chalk sketch of an unidentified machine
A rough draft in sanguigna, noted as 61 braccia
This leaf holds a rough draft in red chalk (sanguigna) of a machine whose purpose is not specified in the note. The only dimension recorded is sixty-one braccia. The faint chalk lines suggest a raised frame or bench with a vertical member and a small plan below; further faded strokes are present but were not transcribed.
