Calvary as an English name for the place is derived from the Latin word for skull (calvaria), which is used in the Vulgate translation of "place of a skull", the explanation given in all four Gospels of the Aramaic word Gulgalta which was the name of the place where Jesus was crucified. The text does not indicate why it was so designated, but several theories have been put forward. One is that as a place of public execution, Calvary may have been strewn with the skulls of abandoned victims (which would be contrary to Jewish burial traditions, but not Roman). Another is that Calvary is named after a nearby cemetery (which is consistent with both of the proposed modern sites). A third is that the name was derived from the physical contour, which would be more consistent with the singular use of the word, i.e., the place of "a skull". While often referred to as "Mount Calvary", it was more likely a small hill or rocky knoll.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where did the Romans usually speak Aramaic?
