Terrestrial telescope consisting of seven main tubes, a separate tube for the objective, and three small tubes for the compound eyepiece. Of the seven main tubes, six are made of wood and have octagonal sections; the seventh, the smallest, is cylindrical. It is made of cardboard and covered with red marbled paper. The plano-convex objective is contained in a little cardboard tube that slides into the largest draw tube. The objective is signed on the glass and on the diaphragm by the maker, Eustachio Divini. The complex optical configuration gave the instrument a magnification of c. 55.
