Romans never "crucified" anyone. They IIRC did have several radical ways to execute people, like putting them in a sack with a bunch of wild cats.
The SOLE source of evidence of "crucifying" not just Jesus but supposedly thousand of rebel slaves along miles of main roads after Spartacus is one ankle bone with a nail...from a carpentry shop.

What the Romans did find, when they got to England, was the Brits making good use of Scarecrows. No doubt they adopted them, and sooner or later a Jew saw them out in a field, from a distance, and the Jewish mind goes where it always goes.
