an English explorer who is notable for his account of a 1605 expedition to America in which describes native peoples and fauna of northern New England. He describes a journey along a "great river", but the identity of the river is not known for certain. Rosier was among those who sailed to present-day Maine with Bartholomew Gosnold in 1602. there were three versions of Rosier's account of the voyage: a now-lost journal; a manuscript version obtained first by Richard Hakluyt and then by Purchas, who abridged it in Purchas his Pilgrimes in 1624; and yet another manuscript, perhaps edited by Hakluyt, which was published in 1605.
