Hooke's 1665 Micrographia — first major illustrated microscopic survey and the coining of 'cell'
Published in January 1665 by John Martyn and James Allestry (Printers to the Royal Society), 'Micrographia: or some Physiological Descriptions of Minute Bodies made by Magnifying Glasses, with Observations and Inquiries thereupon' is Hooke's career-defining work and one of the most influential scientific books of the seventeenth century. The folio volume presents sixty observations of microscopic specimens, accompanied by Hooke's own large-scale engravings (Hooke was a trained draughtsman of considerable skill; the engravings were a major part of the book's impact). Major observations include: the point of a sharp needle (showing it to be quite imperfectly pointed); the edge of a razor; cloth-fibres; the texture of cork (where Hooke coins the biological term 'cell' — observing that cork has 'a great many little Boxes' which 'look not unlike a Honey-comb', the partitions of which he calls 'cells'); blue mould; mites; the seeds of various plants; the eye of a fly (showing the compound-eye structure); the foot of a fly (showing the suckers); the feathers of birds; the structure of snowflakes; the louse; the flea (the book's most famous image — a foldout engraving showing the flea at unprecedented detail). The 'cell' observation in Observation XVIII would become foundational for biology, though Hooke had no notion that the structures he saw were living units (he thought them merely empty boxes in cork). The book made Hooke a major intellectual celebrity; Samuel Pepys recorded staying up until two in the morning reading it; Christopher Wren and Robert Boyle praised it; it shaped subsequent microscopy and was the principal vehicle for the popular reception of Royal Society experimental philosophy in Restoration England.

School Embodiments
Founding Royal-Society experimental-microscopic work.
"By the help of microscopes, there is nothing so small as to escape our inquiry." (Micrographia, preface)
Corpuscular-atomist hypotheses from microscopic observations.
"The figures of crystals and snowflakes suggest a corpuscular structure." (Micrographia, Observation XIV)
Realism about the structure disclosed by the microscope.
"What appears uniform to the naked eye is shown to be highly structured." (Micrographia, preface)
Strong empiricist methodology of the Royal Society.
"The use of the senses is the way to natural philosophy." (Micrographia, preface)
Mechanist tradition.
Newtonian tradition.
Internal Tensions
Hooke's career-defining publication; coined 'cell' in biology and supplied iconic engravings of the microscopic world. The book's reception was immense: Pepys's all-night reading, the Royal Society's circulation, the popular reception of Restoration experimental philosophy through Micrographia's accessible-illustrated format.
I. Time
1665. Hooke was 30 and had been Royal Society Curator of Experiments since 1662 (a position created for him to demonstrate weekly experiments at the Society's meetings).
Attributes
II. Space
London — the Royal Society's early years at Gresham College, and Hooke's lodgings at Gresham where he ground his own lenses and built his own microscopes.
Attributes
III. Matter
Illustrated folio of microscopic observations (~250 pages with extensive foldout engravings). Form is observation-by-observation: each observation has a heading, a description, and an engraved illustration.
Attributes
IV. Observer
Early Hooke as Curator of Experiments. The observer-experimentalist is the principal Royal Society experimental philosopher of the 1660s — Hooke's relationships with Newton, Boyle, Wren, and the entire Royal Society scientific establishment all centered on his role as experimentalist.
Attributes
V. Energy
Founding-experimental energies of the Royal Society. Micrographia was the Royal Society's most successful single early publication — read across Europe, translated, and continuously reissued.
Attributes
VI. Information
Sixty observations with large-format engravings. The engravings (Hooke's own) are themselves a major scientific-historical document — they shaped the visual culture of early modern science.
