Anatomical model of an eye, Italy, 1601-1700
This ivory and glass model of the eye unscrews to show the different parts, including the cornea (part of the outer coating of the eyeball), the pupil, the iris, the jelly-like vitreous humour that fills most of the eyeball, and the optic nerve that transmits messages to the brain. The muscles are indicated using painted red paper and the eye is complete with eye lids. The model has its own case, possibly made of rosewood, and there is a rose carved into the bottom. This model was almost certainly used to help teach the anatomy and workings of the eye.
