Just a thought, Since i know the Romans were into Crucifixion as well as the Carthaginians. Although Hanging criminals and being sentenced to the arena's for sport were also practiced if a person was condemned to die. I would like to know what people would think if this were true.
I don't see the Cross as a symbol of divinity. Christians don't worship it. (Well, maybe some do, but I don't). It's not divine and has no power within itself, but the One who hung on the Cross is divine and has all the power. It's simply a reminder, or a symbol, yes, of the suffering our Savior went through.
And short answer to your question----We'll never know, will we?!
Christ , was not hung . He was crucified , on a cross , therefor a cross is the devine symbol . however , the cross is not what is worshiped , its Jesus and the price he paid to clense our sins , no matter how Christ dead , its not how it happened its what he did that matters .
I've asked myself the same question a couple of times, or something like it. I guess that might very well be the case. It's a good thing Jesus wasn't crucified by a Bond villain or a convoluted Rube Goldberg death machine might be the most prominent symbol of our faith. Not easy to carve for a pendant.
