Phase of the Moon rising in Nuremberg.

This historical astronomical plate illustrates a partial lunar eclipse observed from Nuremberg on April 17, 1755.

At the top left, a geometric diagram shows the "Earth's shadow" as a large dark circle intersected by the "Path of the Moon" along the "Ecliptic." It marks the points of start ("Beginning"), maximum obscuration, and end ("End"), with a scale for "Digits of the lunar diameter."

The top right contains a boxed table of "Moments of Calculation," listing celestial coordinates, diameters, and parallax values used to calculate the eclipse's progression.

In the center, a large curved diagram labeled "Celestial projection of the phases and times for the Nuremberg Meridian" maps the moon's phases and timing relative to the Nuremberg meridian, featuring an hour scale from VI to IX.

At the bottom left, another boxed table, "General diagram," specifies the exact local times for the eclipse phases in Nuremberg.

At the bottom right, a circular map of the world centered on Europe and Africa, titled "Phase of the Moon rising in Nuremberg," shows the moon's position over Earth at the moment of the eclipse.
