Eat out today and you might not get a plate. The current fashion in the restaurant industry is to experiment with serving food on unusual objects. For a full range of of serving vessels currently in use do visit: https://twitter.com/WeWantPlates?ref_src=twsrc^tfw
However, fashion in eating and drinking is nothing new. Research on the glass found during the Masada siege works' excavation showed that whilst the ordinary legionaries had simple drinking vessels, the commanders were quite different. They drank from a variety of highly decorated glass vessels. No evidence is reported for Romans dining off of sandles or having the soup in helmets....
Camp F at Masada, southern Judea, is part of the siege works constructed by the Roman Army against the Jewish rebels during the Jewish Revolt. It is divided into two areas and chronological stages: the larger outer Camp F1, is dated to the time of the siege against Masada, until its fall in 73/4AD and the inner Camp F2, is dated between 106 and 113AD or even later in 115–117AD A group of luxury and common mostly drinking vessels were discovered in the 1995 Excavations in Camp F at Masada, concentrated in several units that probably served as the senior officers living quarters and headquarters, and the common soldiers dwellings. Their analysis will be used to study cultural and social implications as a reflection of the personal drinking habits of high ranked commanders and legionaries of the Roman army.
