This ancient Roman gate is made of iron. It is typical of the entrance gates to the oppida (fortresses).
Two towers flanked the entryway. The entryway was protected by a portcullis (huge metal grating) at each end of the entryway. These could be raised or lowered. They were raised early in the morning to permit villagers to come into the fortress to sell their goods. They were lowered at night and also in times of enemy attack.
Artist rendering of an Iron Age oppidum.
In the ancient world people lived at high elevations near permanent water sources. These "high places" were often fortified mounds, which in Hebrew are called "ophel" (Hebrew עֹ֫פֶל).
These fortified mounds gave security to the residents. The guards who watched the surroundings area from the walls were called "oplites." Here we see the same root as in the Hebrew word ophel. The root is OP and it pertains to seeing (optics, optic nerve, etc.); armed guards (opiltes); walled towns (oppida), and sun shrines/temples (Opiru). The Opiru were served by a caste of priests known in the ancient world as Ha'piru, Ha'biru or 'Apiru. The word Habiru is rendered as "Hebrew" in English Bibles.
