A letter written by Galileo Galilei that defended the heliocentric model of the solar system and challenged religious doctrines has recently been discovered، as the Technical Times said.
The 7-page letter addressed to a friend and was penned on Dec. 21، 1613 is believed to be the beginning of the renowned astronomer's battle with the Catholic Church. The letter that historians long thought has been lost was discovered by a postdoctoral science historian Salvatore Ricciardo of the University of Bergamo in Italy. He visited the Royal Society in August for a different purpose but found an important artifact in history instead.
"I thought، 'I can't believe that I have discovered the letter that virtually all Galileo scholars thought to be hopelessly lost،'" he said to Nature. "It seemed even more incredible because the letter was not in an obscure library، but in the Royal Society library."
Galileo Galilei's Battle With Catholic Church Two differing version of the letter exist: one was sent to the Inquisition in Rome by a Dominican friar while the other، with less accusatory language، is now kept in the Vatical Secret Archives. Because the original was thought to be lost، historians had no way of knowing if one of the letters was edited by the clergymen to help their heresy case against the astronomer.
