Promethei Terra is a large Martian region covering 3300 km at its broadest extent. It lies to the east of the massive
Hellas basin. Like much of the southern part of the planet it is a heavily cratered, highland region. Promethei Terra was named for a classic
albedo feature of Mars, with the original name derived from that of the Greek god
Prometheus. Promethei Terra lies mostly in the
Hellas quadrangle of Mars.
