[4] The earliest mention of Adams in the printed literature of the sixteenth century is by his contemporary, Richard Eden, the father of English geography.
Eden writes: "Wheras I have before (p. 252) made mention howe Moscouia was in our tyme discoured by the direction and information of the sayde master Sebastian [Cabote] who longe before had this secreate in his minde, I shall not neede here to describe that viage, forasmuch as the same is largely and faithfully written in the Latyn tonge by that lerned young man, Clement Adams, scol mayster to the Queenes henshemen (i.e. pages of honour) as he received it at the mouth of the sayde Richard Chancelor.
A contemporary copy of Cabot's map, discovered in Germany, is preserved in the Bibliothèque nationale de France, the original of which is now lost, in a volume edited by Nathan Chytræus, first published in 1594.
The title runs thus: ‘Nova Anglorum ad Moscovitas navigatio Hugone Willowbeio equite classis præfecto, et Richardo Cancelero nauarcho.
This is followed by a translation headed thus: ‘The newe Nauigation and discouerie of the kingdome of Moscouia, by the North east, in the yeere 1553; Enterprised by Sir Hugh Willoughbie, knight, and perfourmed by Richard Chanceler, Pilot maior of the voyage.
