" I am fully perswaded that our countrie is not inferiour to any for men of rare 

 knowledge, singular explication, and exquisite execution of the artes mathema- 

 ticke, for what strangers may be compared with M. Thomas Digges, Esquire, our 

 countryman, the great master of archmastrie ? and for theoretical speculations and 

 most cunning calculation, M. Dee and M. Thomas Heriotts are hardly to be 

 matched." The Seaman's Secrets, by John Davis, 1594.
