Potentially history-altering discovery by Limerick researcher

A POTENTIALLY history-altering finding by a University of Limerick (UL) researcher may provide the world with the “most detailed technical analysis of a telescope provenly made” by the famous astronomer and scientist Galileo Galilei. A previously unknown seventeenth-century description of a four-lens terrestrial telescope attributed to Galileo was discovered by Dr José María Moreno Madrid, a researcher at UL’s School of History and Geography. Dr Moreno Madrid made the fascinating discovery while studying a 1666 manuscript written by a Spanish Dominican friar named Ignacio Muñoz. In a document titled De Tellescopiis Stellarum, Muñoz provided a component-by-component description of a four-lens telescope described as ‘fabricatum a Galilaeo’, or ‘manufactured by Galileo’. Existing historical records situate the first four-lens telescopes at around 1643 – 1645, with surveys of telescope production in Europe during the second half of the century suggesting that production became widespread from the 1640s onwards. Now published in the Annals of Science, Dr Moreno Madrid’s research provides evidence which suggests that not only did experimentation with the four-lens telescope take place earlier than believed and documented, but it could be attributed to none other than Galileo himself. Dr Moreno Madrid said: “If, as the text claims, the telescope analysed was indeed manufactured by Galileo, then the earliest known experimentation with four-lens telescopes would have to be pushed back to 1630 at the latest and credited to him.” “Moreover, Muñoz’s De Tellescopiis Stellarum would become the most detailed technical analysis of a telescope provenly made by Galileo – and, somewhat paradoxically, it would concern a four-lens telescope rather than the Galilean design that ultimately came to bear his name.” With no further mention of the telescope in the Marquis de Mancera’s correspondences with the Spanish court, this sole document presents evidence that could shift our understanding of the history of early modern telescopes, and of Galileo’s in particular. Dr Moreno Madrid added: “I believe that the unambiguous attribution of the telescope in the manuscript, together with the documentary evidence that three telescopes made by Galileo – whose optical configuration remain unspecified – may have been accessible to Mancera through his connections at the Spanish court, at the very least invites consideration of this possibility”. Whether or not the telescope can be definitively attributed to Galileo, Dr Moreno Madrid says Muñoz’s manuscript holds significant importance in expanding the knowledge base for technical descriptions of seventeenth-century telescopes and underscoring these instruments as objects of prestige at the time. Now, Dr Moreno Madrid hopes his research will form the basis of further exploration and discovery, saying: “It is to be hoped that new documentary or material evidence will soon emerge to confirm the telescope’s attribution and further enhance our understanding of it.” The post Potentially history-altering discovery by Limerick researcher appeared first on Limerick Post.
