Though Raven is considered to be the wanton, sneaky, mischievous trickster, he is also an important messenger and go-between the spirit and human world, as he is credited with many positive outcomes regardless of his infamous shenanigans, including discovering mankind in a clam shell, bringing salmon to the people, and releasing the sun, moon and stars to the world that was previously in darkness. He is the most famed of all creatures on the Pacific Northwest Coast.
The Haida are divided into the Eagle and Raven Clans. Each moiety has their own hereditary rights to certain crests, while they also share some crests. Shared crests include the Killer Whale, Hawk, Raven and Sea Wolf. Other crests, such as the Eagle, Beaver, Frog and Dragonfly belong exclusively to Eagle Clan, while Grizzly Bear, Black Bear, Moon, Shark and Wolf are exclusive to Raven Clan.
Within these two moieties are a number of lineages belonging to each side. Social organization among the Haida is matrilineal, and dictates that marriages must only take place between moieties, but not within them. Children inherit their clan from their mother, as well as property, dances, stories, and songs. Even Chiefs receive their title through their maternal line.
When Eagle and Raven are depicted together, they symbolize the joining of these moieties through love and marriage. Unlike western symbolism of love in hearts and knots, the Haida symbol of love is significant of social ties and ancestral history in imagery of these majestic birds.
