The following book combines two well known works of Langlois into one book. The first part is Numismatique de l'Arménie dans l'antiquité and the second Numismatique de l'Arménie au moyen âge. These two works, originally published in 1859 and 1855 were published, were combined into one work in 1859. The works cover issues of ancient Armenian dynasties, Kiurike, and Cilician Armenia. It was later scanned and made availible online via Google.
