Galileo Galilei: Science vs. faith
[first paragraph of article] Galileo Galilei (1564–1642), professor of mathematics at the University of Padua from 1592 to 1610, was a pillar in the history of our University and a symbol of freedom for research and teaching, well stated in the university motto ‘‘Universa Universis Patavina Libertas’’ (Total freedom in Padua, open to all the world). He invented the experimental method, based on evidence and calculation (‘‘science is measure’’) and was able, by using the telescope, to confirm the Copernican heliocentric theory, a challenge to the Bible. Bertrand Russell (1872–1970), in his book ‘‘The Problems of Philosophy’’ stated: ‘‘Almost everything that distinguishes modern world from earlier centuries is attributable to science, which achieved the most spectacular triumphs in the seventeenth century. Together with Harvey, Newton and Keplero, Galileo was a protagonist of this scientific revolution in the late Renaissance’’.
New Interpretation of Galileo’s Arthritis and Blindness
Galileo Galilei (1564-1642) complained of several disorders during his life, the most important of which were chronic arthritic pains and bilateral blindness. These symptoms might be results from an immune rheumatic disease, namely reactive arthritis (urethritis, uveitis, arthritis), when Galileo started suffering with an episode of fever in June 1593. Padua University owns the fifth lumbar vertebra of the great scientist and we performed a series of anthropological and radiographic analyses on it. The anthropological measurements showed that the shape of the vertebra was normal as to exclude significant diseases. The study through radiography and Computed Tomography showed only a mild arthrosis documented by small osteophytosis. Eventually the disease evolved into blindness with a pannus restricting the pupils (uveitis). These findings support the occurrence of reactive arthritis. Alternatively to urethral infection, Galileo could have suffered from Chlamydia pneumoniae infection in 1593, which was complicated by reactive arthritis a couple of weeks later. Thereafter he complained several episodes of recurrent arthritis, which eventually culminated into uveitis and bilateral blindness.
The enigma of Galileo's eyesight: some novel observations on Galileo Galilei's vision and his progression to blindness.
Galileo Galilei became blind. Before this happened he revealed that his left eye had always had less than perfect vision. A study of his written works, his handwriting, and the originals of the portraits undertaken during his lifetime indicate that this probably was the case. These portraits suggest that his left eye tended to lose fixation and that, at the age of 60, he suffered from a mucocoele of the right frontal sinus; but these conditions would not have caused blindness. Considering the systemic diseases from which he suffered over his lifetime, he could possibly have had a long standing uveitis with secondary pupillary block glaucoma, common in those with the group of conditions classified as sero-negative arthropathies. Posterior scleritis with secondary glaucoma is less likely. If either of these were the cause, then the disease was probably triggered by a well-documented, severe acute illness as a young adult, the inflammation being localized to the eye as a result of severe recurrent conjunctival infections in his youth. The intermittent nature of the visual loss, the normal appearance of the cornea and pupils in his portraits, the absence of any evidence of inflammatory joint disease, the presence of halos, and the severe nature of the pain-combined with the high level of visual acuity in between attacks and its persistence until the last few weeks of vision means that angle-closure glaucoma must also be considered. These suggestions might be confirmed or refuted by studying his remains. Application has been made for this to be done.
