Hades
Greco-Roman mythology.
the roman name for aphrodite is venus.
Apollo doesn't have a roman name
Helios was the Greek name. His name was Sol in Roman mythology.
As far as I am concerned, there is no Roman name for Asgard, because Asgard is Norse mythology, and really has no counterpart like Greco-Roman mythology.
Morpheus' Roman name is the same as it is in Greek mythology.
Roman mythology
Apollo's name in both Greek and Roman mythology was Apollo.
The ruler of the underworld in Greek mythology is the god Hades. In Roman mythology, his name is Pluto. He also has a queen who rules with him. Her Greek name is Persephone and her Roman name is Proserpine. I think in egyptian Hades is Osiris
Mercury's Roman name is Mercury. And his Greek name is Hermes.
Proserpina.
