Caption: "Microscope manufactured by Christopher Cock (17th century) of London for Robert Hooke (1635--1703). Hooke is believed to have used this microscope for the observations that formed the basis of his book Micrographia (1665)." (Slightly edited.)
The microscope suffered badly from spherical aberration.
