Crucifixion — torture stake or cross?
Apparently there were at least three kinds of crosses used by the Romans to crucify criminals. One was called ‘Crux decussate’ in the shape of an ‘X’. The second, Crux Commissa, in the form of a ‘T’. Finally, they used, the Crux immissa in the form of a small 't' like what we usually see in the movies, typcical church crucifixes, or on jewelry, etc.
Is there any ancient records of the symbol of the cross in church history that would indicate what type of cross the Romans actually used to crucify Christ?
I ask this trivia type question only because this is the type of thing my older Sunday school kids will throw at me and I have no answer.
