These ancient Celtic Crosses in Northern Ireland depict scenes representing the account of Genesis Chapter 3 where Adam and Eve are covering their genitals with their hands, evidently in shame. Of course, once upon a time adults understood that the real original sin was not merely eating an apple. The crosses are esteemed to date to the 10th Century. For more about that, see our article, Shemitic Idioms and Genesis Chapter Three
