This paper presents examples of mathematical models which have almost passed into oblivion, yet a few decades ago still played a significant role in the teaching of mathematics. In the late nineteenth century such devices started to be produced on a large scale for schools and universities. The Jagiellonian University Museum has three such models in perfect condition in its collections.
