When I was in grade school, I couldn't have cared less about history. Now, I can't get enough. From the Mayans, to Titanic, even Ancient Rome. I remember being in 3rd or 4th grade when I learned that Julius Caesar was not that cartoon guy holding a pizza on a spear, but an actual person.
Idus Martias, translated as "The Ides of March" was a date on the Roman calendar, which falls on March 15th. In Ancient Rome, a festival for Anna Perenna was held on the Ides of March, but it wouldn't be long before another event would leave the Anna Perenna festival in the shadows.
