All right, here it is:
Preflight: change scientist in Izmit to laborer, put him on hill next to river
1: Edrine curragh->settler (3); dinkies continue exploring; drop sci to 40% and change 2 scientists to taxmen, still get lit next turn; change citizen in Bursa to taxman to prevent riots
2: learn lit, use "big picture" to switch all temples to libraries (this is permitted by the rules we're playing under, right?); Uskudar library->worker (3), Konya library->worker (3); 1 dinky sinks; switch barracks in Suez to library; make scientist in Kafa to prevent riots
Trades: trade lit to Egypt for math, 54 gold, and 3 gpt (couldn't get map making)
trade lit and 69 gold to England for philosophy (best deal we could get)
set research to horseback riding, can get in 4 turns at 50% with -5gpt (after switching taxmen back to scientists)
We have a palace prebuild in progress, but no wonders are available (every AA wonder has been built already, along with Sun Tzu's); switch to library, wasting 18 shields--IMHO the least bad option
3: Istanbul library->worker (1), Izmit library->worker (2); 1 dinky sinks, but another dinky spots light blue borders!

unfortunately, not in contact range yet

: ; change barracks in Ankara to library
4: Istanbul worker->swordsman (3), Edrine settler->library (5); dinky that found borders sinks!

; warrior in Istanbul moves toward Suez for MP; drop sci to 40, change 3 scientists to taxmen, HBR in 2, +8 gpt; however, England and Egypt have it now and are in the MA!
5: Uskudar worker->cat (5); Izmit worker->curragh (3); Antalya library->worker (5); Konya worker->cat (5)
6: learn HBR, code of laws in 11 at 40 (the cheapest remaining AA tech), -2 gpt; Ankara library->worker (4); last dinky sinks; Mugla founded, library in 20
7: Istanbul sword->cat (2), Iznik library->worker (5)
8: Izmit curragh->curragh (3)
9: Istanbul cat->cat (2), Edrine library->worker (2); Ankara riots, change citizen to scientist
10: Antalya worker->cat (10), Konya cat->cat (5)
Well, I built some libraries, got us some more workers, and located another civ (though I was unable to contact them), so not bad, I guess. We still need more workers, though; I'd say at least 8 more (for a total of 20). After that, we need to acquire some more territory. England and Egypt are both bigger, stronger, and more advanced than we are; we can't let that go on forever.
Here's the save:
