Summary: We examine Napier's twentyyear work in order to publish his tables of logarithm. The tables were a tool for the simplification of trigonometric calculations required by cartography and astronomy of XVI century. These boards implicitly identify the famous constant ``$e$'', unknown by Napier, by means of which an original kinematic definition became possible.
