Evidence for the Mycenaean Age Paralleling the El Amarna Age

This evidence is based on papyrus fragments found by Pendlebury in 1936 in House R 43:2 when he wrote, “finds in this building included a complete Mycenaean vase (the second complete example found on the site) and a number of fragments of papyrus - still awaiting a proper treatment.’ This treatment was accomplished by Bridget Leach (Conservation Department of the British Museum). All the fragments of the painted papyrus portion have now been positioned with reasonable certainty. They show 3 accumulations of small fragments (right to left) as part of a battle scene, a) `Libyan archers are depicted attacking a fallen Egyptian in a rocky terrain’; b) the middle scene shows running troops and an archer shooting an arrow; c) running foot soldiers. The significance of these scenes is that they show the unusual feature of a type of helmet on some of the running troops which are said to be remarkably similar to boar tusk helmets as found in Mycenaean images. One of the helmeted figures is also interpreted to wear a cropped ox-hide tunic which also has Aegean parallels.[2100]
I have long thought that as Crete fell into eclipse after its maritime strength was destroyed by tsunamis from Thera, that artists and artisans may have made there way to Egypt and more specifically Amarna. In addition I imagine that mainland Greeks also made their way to Crete and thence to Egypt. There was definitely commerce between the two.
