Most studies of weapons consist largely of formal and contextual analyses designed to provide chrono-typologies based on the stratigraphic contexts. This fundamental methodological tool cannot however provide precise information about the life of weapons or, more particularly, answer some of the questions concerning their purpose, the way they function, and also the way they are maintained, repaired, and finally abandoned. Although experimental archaeology can by no means provide all the answers, this complementary approach enables the hypotheses suggested by chrono-typology to be tested, thus enhancing our understanding and interpretation of the weapons.
