This plaster cast, created by James Nasmyth before 1873, depicts an overhead view of the lunar craters Arzachel, Ptolemaeus, and Alphonsus. Nasmyth, a renowned inventor and engineer, was fascinated by the moon and created numerous models like this to understand its topography. The cast is part of a larger scientific and artistic endeavor, showcasing the detail and complexity of the lunar surface. The work is a testament to both Nasmyth's skill as a modeler and his dedication to advancing scientific understanding of the cosmos.
