ally to have in Mediterranean power politics, at least by the 14th century as "vassals of the pharaoh", leading Cretan tribute-bearers to be depicted on Egyptian tombs such as those of the top officials Rekmire and Senmut. On mainland Greece during the shaft-grave era at Mycenae, there is little evidence for major Mycenaean fortifications; the citadels follow the destruction of nearly all neopalatial Cretan sites. Warfare by other contemporaries of the ancient Minoans, such as the Egyptians and the Hittites, is well-documented. Skepticism and weaponry Despite finding ruined watchtowers and fortification walls, Evans said that there was little evidence of ancient Minoan fortifications. According to Stylianos Alexiou (in Kretologia 8), a number of sites (especially early and middle Minoan sites such as Aghia Photia) are built on hilltops or otherwise fortified. Lucia Nixon wrote: Chester Starr said in "Minoan Flower Lovers" that since Shang China and the Maya had unfortified centers and engaged in frontier struggles, a lack of fortifications alone does not prove that the Minoans were a peaceful civilization unparalleled in history. In 1998, when Minoan archaeologists met in a Belgian conference to discuss the possibility that the Pax Minoica was outdated, evidence of Minoan war was still scanty. According to Jan Driessen, the Minoans frequently depicted "weapons" in their art in a ritual context: Stella Chryssoulaki's work on small outposts (or guardhouses) in eastern Crete indicates a possible defensive system; type A (high-quality) Minoan swords were found in the palaces of Mallia and Zarkos (see Sanders, AJA 65, 67, Hoeckmann, JRGZM 27, or Rehak and Younger, AJA 102). Keith Branigan estimated that 95 percent of Minoan "weapons" had hafting (hilts or handles) which would have prevented their use as such. However, tests of replicas indicated that the weapons could cut flesh down to the bone (and score the bone's surface) without damaging the weapons themselves. According to Paul Rehak, Minoan figure-eight shields could not have been used for fighting or hunting, since they were too cumbersome. Although Cheryl Floyd concluded that Minoan "weapons" were tools used for mundane tasks such as meat processing, Middle Minoan "rapiers nearly three feet in length" have been found. Charles Gates argues that the absence of warfare in Minoan art does not prove it did not occur because there is no correlation between a society's artistic depiction of warfare and how often said society is involved in conflict.
