Just imagine living in the times of Christ or the apostles and as the church was being birthed. Or possibly 100 or 500 years later. Just imagine the cultures, the way of life and the art of those times. History tells us a lot. Over the years I have read some great books and viewed some great sites about Early Christian Art and found them amazing. Just like seeing great pictures of the history of Egypt or the Aztecs, it's amazing to see history of peoples from generations ago.
Something else that's fun to do is to pick a year in time and see what events unfolded. For example in 1920 or the 30's or the 40's or possibly on your birthday, the day you got married or on the day your child was born. A great site to do that at is called Brainy History. It's interesting, fun and also surprising.
