Stygiana

Stygiana refers to a geographical region or a characteristic associated with the river Styx, a mythological river in the underworld of Greek mythology. The Styx is often depicted as a boundary between the world of the living and the realm of the dead.

The term "Stygian" is frequently used in literature and art to evoke a sense of darkness, gloom, and the infernal. It carries connotations of the underworld, death, and the Styx's mythical properties, such as its association with oaths and its uncrossable nature for most souls.

In classical literature, the Styx plays a significant role in various myths, including those involving the gods and heroes. It is often described as a dark, sluggish, and foreboding body of water. The adjective "Stygian" has therefore become a widely recognized symbol of these dark and infernal qualities.
