In 1665, Robert Hooke, a brilliant scientist of his time, published a work entitled Micrographia, most of which was concerned with the microscopical observations he made using one of his microscopes. As a talented illustrator, Hooke filled the, now widely recognised as historically significant, book with many extremely fine and detailed drawings. It was the first to be written and illustrated about plants, insects and other miscellaneous objects as seen through a microscope. Samuel Pepys, a great admirer of Hooke wrote of Micrographia in his diary, "Before I went to bed I sat up till two o'clock in my chamber reading of Mr. Hooke's Microscopicall Observations, the most ingenious book that ever I read in my life."
