Honestly, this should come as no surprise. There have always been Africoid peoples in Cannan in fact, they are still there today. The area around Jericho is full of them and there are still bedouin in the Sinai and the Negev who are as black as a Hershey bar. Come on now, all those nappy headed Jews running around had to get that hair from somewhere. The world's ppulations have never been isolated. That part of the world has seen multiple migrations from all directions.
These are supposedly Hebrews (or Israelites) in Babylon. I don't know about you, but they pretty much look like an "average" African person to me, thick lips, dilated nostrils, kinky textured braids/locs 'n all.
Here's another one from the Assyrian conquest of Judah
Looks like peppercorn hair & beard to me, although I've heard people claim that it's actually a helmet (preposterous, right?)
I don't know who these people are, some sources say they're Elamites, some say they're Persians (their hairstyle(s) & beard looks similar to ancient reliefs portraying Darius I, Xerxes etc) . I think this was found in a palace in Iran. I believe the place is called Susa/Shushan.
This ancient relief is part of a large limestone block that adorned the south-western palace of Ashurbanipal at Nineveh. It reveals Assyria's victorious troops carrying away booty and the soldiers of Ashurbanipal leading away the cities prisoners into captivity. A real life illustration of the Biblical text that reads:
"In the ninth year of Hoshea the king of Assyria took Samaria, and carried Israel away into Assyria, and placed them in Halah and in Habor [by] the river of Gozan, and in the cities of the Medes." - 2 Kings 17:6
From what I've seen of (relatively) ancient depictions of peoples of the Levant/Mesopotamia/Canaan/Persia/Arabia, the natives appear to have African origins. I haven't seen any depictions of natives who look anything like the current peoples inhabiting these lands. I guess that's why all biblical movies are whitewashed; because they'd never spend millions of dollars on a black/african story for white/pink people (who are the majority of the consumers) .
I was looking through the ES link you posted Son of Ra and I noticed the poster added a picture that is supposed to depict Canaanites on a boat. They look identical to depictions I've seen of Egyptians in that style. How do we know they're Canaanites just because the museum who 'owns' the piece says they are ?
