In Catholic churches it was easy to find out about the bible. Even for those who could not read, iliterate. Paitings or statues told a story. My upbringing wasn't exactly Christian. Yet I do know that the story I was referring to played about 2000 years ago. Give or take a few years.
Elsewhere on the www I can read about the invention of glasses in the 13th century. A bit of discussion and controversy, hence I could be wrong a century or even two. But can someone explain what the geezer with the specs on the right is doing next to the one wearing a huge cross, ready for cruxifiction on the left?
