Newly discovered 1666 manuscript may trace four-lens telescope experiments to Galileo
A potentially history-altering finding by a University of Limerick researcher may provide the most detailed technical analysis of a telescope demonstrably made by the famous astronomer and scientist Galileo Galilei.
A newly discovered 1666 manuscript may revolutionize our understanding of Galileo's telescope experiments, according to a University of Limerick researcher. Dr. José María Moreno Madrid discovered the document while studying the work of a Spanish Dominican friar, Ignacio Muñoz. The manuscript, titled De Tellescopiis Stellarum, provides a detailed description of a four-lens terrestrial telescope, explicitly attributed to Galileo.
If confirmed, this would mean that experiments with four-lens telescopes began in 1630 or earlier, predating previously documented experiments from the 1640s. The manuscript, written by a scholar with expertise in mathematics and astronomy, also includes detailed diagrams and drawings of the instrument. If the attribution is confirmed, it could shift our understanding of the history of early modern telescopes and Galileo's involvement in their development.
