On this day in History, April Fools tradition popularized on Apr 01, 1700. ….Some historians speculate that April Fools’ Day dates back to 1582, when France switched from the Julian calendar to the Gregorian calendar, as called for by the Council of Trent in 1563. People who were slow to get the news or failed to recognize that the start of the new year had moved to January 1 and continued to celebrate it during the last week of March through April 1.
Today is the feast day of St. Jerome, patron saint of librarians, translators and encyclopedists. The Preus Library article by Jane Kemp skillfully describes his life and library:
St. Jerome’s personal library was considered to be the most important private collection of the period. He was a great bibliophile, interested in collecting both pagan and Christian books. His learning was considered unequaled during the time he lived since he was an insatiable reader and had a phenomenal memory for what he learned. Finally, his scholarship broke new ground with his translations of the Bible and Biblical commentaries.
