If you read that Wiki article that's backwards - crux is a latin translation of a greek term that didn't necessarily mean cross and neither did the latin until the convention settled.Presumably the reason those commentating at the time called it a crucifixion was precisely because if was a cross. If it was a tree or a 'T' shape they would have mentioned this, given that they were talking about something they thought was the most important event ever. You don't have to be a devout Christian, and I'm not one, to find this period of historical interest.
