Pre-turn - Sort out some minor things and lower science to 30%, Currency still in 4 turns.

Egypt have maps! They would give Currency for WM, I take it. (edit: I gave them some gold too, but don't remember what?)
Self-research would cost around 190 beakers and 4 turns. Research Map-making at 30%, due in 6 turns.
I see a red city, it's Roman and we haven't even met them yet.
Set Nineveh to market.
260AD - Ellipi library -> market.
Dutch knows how to trade maps too, I give them our WM for their TM.
270AD - Nimrud is founded -> temple.
More civs knows Navigation and I can buy some stuff. Iron or horses? I suppose we have to get iron as we won't wander too far anyways.
I don't want to feed Spain, so I buy iron from Egypt for spices, WM, 17gpt and 10g.
Buy Construction and incense from Maya for 30gpt and spices.
Give spices and 1gpt to Dutch for MapMaking.
We are in Middle Age and get Feudalism as our free tech.
Nineveh gets a scientist, the only specialist needed for now.
We are doing 12gpt atm.
280AD - Babylon library -> market.
A freebie! Dutch establish an embassy in our capitol

310AD - Egypt completes Copernicus.
Spain and America sign peace.
Akkad library -> settler.
Eridu library -> MI.
Use 80 of our 83g to rush the galley, so we can meet those elusive Romans. It was that or embassies...or get it demanded away.
320AD - Spain sign peace with Dutch as well
Rome completes the Great Library.
Nippur galley -> pike.
Egypt have 5.5k gold.
330AD - Nineveh market

-> settler.
With the extra income we can turn up research to 20%, Engineering in 17 turns. No one wants to sell it for 39gpt, it's only doubtful.
I manage to get 14g for WM of Maya, rush temple in Larsa for 64g. We need to expand the borders around there.
340AD - Larsa temple -> worker.
350AD - Spain and Egypt sign alliance against Maya.
What's going on with our people, this is the third palace-expansion I got in a few turns.
Our galley is a few turns from the Roman city.
