Galileo was now in the seventieth year of hisage, and but for the persecution of those whoought to have cherished and revered him, hislife might have been as happy to himself as itwas beneficial to mankind. In the midst of hisresearches and discoveries, which he prosecutedwith the greatest assiduity, he was summonedbefore the tribunal of the inquisition, as a manof the most obnoxious and dangerous princi-ples; and on the 22d of June, 1663, the fol-lowing arret was pronounced against him, byseven cardinals, who were appointed his judges.It is a curious specimen of catholic infallibility;and as I am indebted for it to a member of thatcommunity, I shall give it you in his ownwords.
