- Description
- This white plaster model of a third order surface has a square base with two high peaks and a lower peak that extends toward a middle space between the two higher ones (in this example, it does not reach that point). Two lines parallel to the base and to one another, as well as a third curve that joins these lines. A paper tag on the base reads: 47. Another paper tag reads: Fl. 3. Ord. mit unipl. Knotenp [...] [/] Verl. v. L. Brill. 7. Ser. [...].
- This model, along with all the models of Series 7, is on the design of Carl Rodenberg of the technical high school in Munich.. It was first published by Brill in 1881.
- The object was exhibited at the German Educational Exhibit at the Columbian Exposition, a World’s Fair held in Chicago in 1893. It there was purchased by Wesleyan University in Connecticut, and subsequently was donated to the Smithsonian.
