Angliae Regni florentissimi nova descripto, actore Humfredo Lhuyd Denbygiense 1573
Abraham Ortelius was more of a map dealer than engraver who was the first to arrange to have his maps enrgraved to a uniform size for his atlas (many being engraved by Frans Hogenberg) - the atlas was a major success and many editions followed. This map appeared in Ortelius's first supplement (or Additamentum) and is based on a manuscript from Humphrey Lhuyd who died in 1568 - it appeared in all subssequent editions and finally in the historical section of the 1606 English edition - 2 states are known, the first (as illustrated here) had the scale bar 30-40-60-60which was corrected from 1587 onwards.
