Here's the situation:

Z=Zulus
G=Greeks
S=Sumerians
A=Aggie's suspected position
For a seafaring civ, sailing to Aggie's island takes about 6 (galley) turns, regarding the route marked as a white line in the mini map and regarding one *possible* point of disembarkment at Aggie north-western coast. I marked the latter on the main map view with a white X from 'my' perspective.
Leptis Minor and Hippo will produce lumber-accellerated canoes which get upgraded in some harbour city. I'm not sure how big (err, small?) the force will look like...
some other stuff:
Aggie built a temple in Madrid at some point. Bah, "culture"...
Greece just got mysticism (no contact to Sumeria, though). Still no trade.
