 The charter was first published in 1681 by Jean Mabillon in his "De Re diplomatica".As the document long predates the general adoption of Anno Domini dating, there was initially a dispute over whether it belonged to the reign of King Chlothar II or King Chlothar III.Modern historians confidently date it to the sixteenth year of the reign of Chlothar III, from which the Anno Domini date of 673 is deduced.
