Phoenomena solis a luna tecti lunae per umbram telluris obscuratae

The page exhibits severe bleed-through or ghosting from the reverse side; nearly all visible text is mirrored. The original ink on this side is very faded, making the primary diagrams difficult to discern.

This page contains several astronomical or cartographic diagrams.

• In the upper left, there is a large, partially shaded irregular shape, possibly representing a phase of a celestial body or a landmass.
• In the lower left is a prominent circular globe, intricately shaded to depict surface features such as craters or topographical terrain, likely representing the Moon.
• The central and right portions of the page are filled with faint geometric constructions, including concentric circles, intersecting arcs, and horizontal linear scales with tick marks, characteristic of celestial projections or mathematical instruments.
• A significant amount of text is visible but is reversed (mirrored), indicating it is bleed-through from the following page. This includes a heading near the top right that appears to be "Celestial projection..." and a larger block of text in the lower right beginning with the word "DELINEATION".
