This chart is one of the earliest extant to show soundings as far out as 100 fathoms. It was drawn by Thomas Hood, a lecturer in mathematics and navigation, who apparently never went to sea. It is indicative of a growing interest in navigation in the Elizabethan period. Hood was the author of several important works on navigation, including 'The Mariners Guide' (1592).
