Working with famed mathematician, John Napier and using John's ideas regarding logarithms, Henry produced logarithm tables which all mathematicians use today. He is considered the man most responsible for scientists' acceptance of logarithms. He also created logarithm tables to enhance the study of astronomy and navigation. Additionally, he was considered a most distinguished mapmaker. Overall, he was and still is referred to as "Henry Briggs, the Great Mathematician".

 "A Declaration of the State of the Colony and Affaires in Virginia (1622)", an official publication of the Virginia Company of London, addressing the "an assault by Virginia Indians on the English plantations along the James River that took place on March 22, 1622." This unjustified and barbaric attack by the Indians, preceded by 8 years of peace, between the Jamestown colonists and the Indians, "and the company's response to it, marks a point at which colonists, no longer dependent on the Indians economically, began in earnest to kill them and seize their land." The publication also contained a treatise by the mathematician Henry Briggs about the supposed Northwest Passage through Virginia to the South Sea.
