According to Brainerd, the title of the former among the Delawares, as among the New England Indians, was _powwow_, a word meaning "a dreamer;" Chip., _bawadjagan_, a dream; _nind apawe_, I dream; Cree, _pawa-miwin_, a dream. They were the interpreters of the dreams of others, and themselves claimed the power of dreaming truthfully of the future and the absent.[145] In their visions their guardian spirit visited them; they became, in their own words, "all light," and they "could see through men, and knew the thoughts of their hearts."[146] At such times they were also instructed at what spot the hunters could successfully seek game. The other school of the priestly class was called, as we are informed by Mr. Heckewelder, _medeu_.[147] This is the same term which we find in Chipeway as _mide_ (_medaween_, Schoolcraft), and in Cree as _mitew_, meaning a conjurer, a member of the Great Medicine Lodge.[148] I suspect the word is from _m'iteh_, heart (Chip. _k'ide_, thy heart), as this organ was considered the source and centre of life and the emotions, and is constantly spoken of in a figurative sense in Indian conversation and oratory. Among the natives around New York Bay there was a body of conjurers who professed great austerity of life. They had no fixed homes, pretended to absolute continence, and both exorcised sickness and officiated at the funeral rites. Their name, as reported by the Dutch, was _kitzinacka_, which is evidently Great Snake (_gitschi_, _achkook_). The interesting fact is added, that at certain periodical festivals a sacrifice was prepared, which it was believed was carried off by a huge serpent.[149] When the missionaries came among the Indians, the shrewd and able natives who had been accustomed to practice on the credulity of their fellows recognized that the new faith would destroy their power, and therefore they attacked it vigorously. Preachers arose among them, and claimed to have had communications from the Great Spirit about all the matters which the Christian teachers talked of. These native exhorters fabricated visions and revelations, and displayed symbolic drawings on deerskins, showing the journey of the soul after death, the path to heaven, the twelve emetics and purges which would clean a man of sin, etc. Such were the famed prophets Papunhank and Wangomen, who set up as rivals in opposition to David Zeisberger; and such those who so constantly frustrated the efforts of the pious Brainerd. Often do both of these self-sacrificing apostles to the Indians complain of the evil influence which such false teachers exerted among the Delawares.[150]
