a "general register of sasines" was set up by statute in 1617, with entry in the register giving the "prescriptive" right (right by normal or correct usage), after so many years, to the "caput" or essence of the barony. the individual who owned the said piece of land containing the "caput" was hence the baron or baroness. uncertainty over armorial right was removed by the "lyon register" being set up by statute in 1672, such that no arms were to be borne in scotland unless validly entered in lyon register.
