The Harii (Latinized West Germanic "warriors") were, according to 1st century CE Roman historian Tacitus, a Germanic people. In his work Germania, Tacitus describes them as painting themselves and their shields black, and attacking at night as a ghostly army, much to the terror of their opponents. Theories have been proposed connecting the Harii to the Einherjar of much later Norse mythology, and to the tradition of the Wild Hunt.
Regarding the Harii, Tacitus writes in Germania:
As for the Harii, quite apart from their strength, which exceeds that of the other tribes I have just listed, they pander to their innate savagery by skill and timing: with black shields and painted bodies, they choose dark nights to fight, and by means of terror and shadow of a ghostly army they cause panic, since no enemy can bear a sight so unexpected and hellish; in every battle the eyes are the first to be conquered.
According to John Lindow, Andy Orchard, and Rudolf Simek connections are commonly drawn between the Harii and the Einherjar of Norse mythology; those that have died and gone to Valhalla ruled over by the god Odin, preparing for the events of Ragnarök. Lindow says that regarding the theorized connection between the Harii and the Einherjar, "many scholars think there may be basis for the myth in an ancient Odin cult, which would be centered on young warriors who entered into an ecstatic relationship with Odin" and that the name Harii has been etymologically connected to the -herjar element of einherjar. Simek says that since the connection has become widespread, "one tends to interpret these obviously living armies of the dead as religiously motivated bands of warriors, who led to the formation of the concept of the einherjar as well as the Wild Hunt".
