representing the components of composite texts are circled. The eye being
couched represents Grassus’ surgical text. The wine glass represents Bailey’s
Treatise, which recommended a moderate lifestyle incorporating wine. The book
represents Guillemeau’s encyclopedic and comprehensive ophthalmic treatise. The
finger near the eye represents Banister’s treatise, which noted the poor
prognostic significance of the palpably hard eye. The crown icon represents the
text of William Read, the royal oculist.
