Uckewallists one of the sects into which the old Flemings, or strict Anabaptist followers of Menno divided. They took their name from Uke Walles, a native of Friesland, who published hid sentiments in 1637. In conjunction with John Leus, he propagated a doctrine of Universalism in which he entertained a favorable opinion of the eternal state of Judas and the rest of Christ's murderers; His argument was this that the period of time which extended from the birth of Christ to the descent of the Holy Ghost was a. time of deep ignorance, during which the Jews were destitute of divine light; and that, of consequence, the sins and enormities which were committed during this interval were in a great measure, excusable, and could not merit tie severest displays of the divine justice. He was excommunicated by the Mennonites of Groningen, and banished from the city by its magistrates, but settled down in East Friesland. This denomination strictly adhered to the doctrine of the Mennonites. Udseus, in Greek mythology, was one of the followers of Cadmus, five of whom murdered each other. He was grandsire of Tiresias.
