Matthew 27:33

Verse 33. A place called Golgotha] From the Hebrew גלגתה or גלגלת, golgoleth, a skull, probably so called from the many skulls of these who had suffered crucifixion and other capital punishments scattered up and down in the place. It is the same as Calvary, Calvaria, i.e. calvi capitis area, the place of bare skulls. Some think the place was thus called, because it was in the form of a human skull. It is likely that it was the place of public execution, similar to the Gemoniae Scalae at Rome.
