John Scolvus

John Scolvus or John of Kolno may have been a navigator of the late 15th century. According to some sources he was among a group of early Europeans to reach the shores of the Americas prior to Columbus, arriving in 1476 as steersman of Didrik Pining, although this view is not supported by contemporary evidence; as he is not mentioned contemporaneously, his identity and even existence have been disputed.
