Usaige et description de l'holomètre, 1567[1]
His Holometer is an instrument for making of angular measurements for surveying. In 1551, Henry II granted Abel a 10-year exclusive patent monopoly on the holometer in exchange for publishing a description of it. A description of an invention in a patent is called a patent “specification”. This first patent specification was entitled "Usage & Description de l'holomètre". Publication was delayed until after the patent expired in 1561.[2]
