Opening leaf: mirror-script with a circle-and-center figure
A full page of untranscribed mirror-writing around a concentric-circle diagram
This leaf is filled from top to bottom with Leonardo's right-to-left mirror-script, including lines that run upside-down along the upper and lower margins; the bundle supplies no transcription, so this untranscribed text is described only by what is visible. At the upper right, beside an old shelfmark, is a small drawn figure of two concentric circles enclosing a central point, with a horizontal diameter line passing through them. Later library stamps and inventory numbers mark the sheet. The precise subject of the writing cannot be determined without a reading of the text.

Concentric circles with a central point and a diameter
A small figure of a larger circle enclosing a smaller circle, sharing a marked central point, with a straight horizontal line drawn through the center as a diameter. It is the only geometric construction on an otherwise text-covered page.
Circle-and-center figure suggesting an eye or luminous body
The nested circles about a single central point resemble the schematic eye or radiating luminous body that recurs in Leonardo's optical diagrams. Without a transcription the reading is tentative, but the figure is consistent with a study of vision or light.
