Terrestrial telescope consisting of nine cardboard tubes. The largest, which contained the objective (missing), is covered with green leather with gilt tooling. The other tubes are covered with red marbled paper. The eyepiece (now missing) was in the smallest tube. The erector survives. It comprises two lenses and is placed in a small little inside the smallest draw tube. The instrument displays all the characteristics of a typical Italian terrestrial telescope of the late seventeenth century.
