notes: label: Description
content: Jacob Metius was a Dutch instrument maker who, in 1608, applied for a patent on an instrument with a convex and a concave lens in a tube, designed “for showing things as if nearby.” This is a cutaway model, made by L.C. Eichner, of what that early telescope might have looked like. The tube is wood, leather covered, with a two draw-tube construction. The objective lens is 1.9 cm diameter, held in place by a bezel of horn. The exterior of the tube is marked in gold leaf: "PERSPI CILIUM"
