Very cool. To put it into perspective, 3400 years ago is roughly the time of Moses and the Exodus.
To put that into perspective, the 18th Dynasty was around much later than the Biblical Moses; the last of the Hyksos kings was captured by King Saul, who was going to spare his life, and the grouchy old prophet Samuel took a knife and killed the unarmed prisoner. In Egypt he was known as Apop II, in the OT as Agog II.
