A remarkable collection of a group of large educational geometric models, from a technical institute, Italy, early 1900s.

Italy 1900.

A remarkable collection of a group of large geometric educational models from an early 20th-century Italian technical school, designed to illustrate the interpenetration and intersection of geometric solids in three-dimensional space. Made of solid wood and approximately 27–28 cm tall, these imposing objects were created as teaching tools for the study of geometry, technical drawing, descriptive geometry, and spatial relations. Each model illustrates a different geometric problem through the physical intersection of prisms, wedges, pyramid shapes, and polyhedral volumes. By transforming abstract mathematical concepts into tangible objects, these models allowed students to visualize complex spatial constructions that would otherwise exist only on paper. In excellent condition, with only a few small chips consistent with their use and era. Castiglione, Turin, Italy, 1900.
