An amphora is an ancient Greek storage vessel, with a constricted neck and two handles (Greek amphi, phoreus, “double handles”). Though a period artifact, we’ve no examples of the amphora in period armory. The default form in Society armory has a flat bottom, as in the illustration; this was often a painted luxury item in ancient Greece [Singer, plate 18]. The utilitarian “wine amphora” has a pointed base, instead of a flat base.
