What does the god tartarus look like?

In Greek mythology, Tartarus is not a god but rather a primordial entity and a deep abyss used as a dungeon of torment for the wicked and a place of punishment for the Titans. It is often depicted as a dark, gloomy pit located far beneath the Earth, surrounded by impenetrable walls. As a personification, Tartarus may be envisioned as a shadowy figure or a vast, ominous void rather than having a distinct physical appearance like other gods.
