Yama \Ya"ma\, n. [Skr. yama a twin.] (Hindoo Myth.)
The king of the infernal regions, corresponding to the Greek
Pluto, and also the judge of departed souls. In later times
he is more exclusively considered the dire judge of all, and
the tormentor of the wicked. He is represented as of a green
color, with red garments, having a crown on his head, his
eyes inflamed, and sitting on a buffalo, with a club and
noose in his hands.
[1913 Webster]
