CoL from Mansa seems tempting, if you could get it for Drama after some beakers put in.
No surprise that no other AI has it yet, no priority for them after Confu was founded.
It took four turns to get CoL from Mansa. That turned out a good idea, thanks. It was a bit slower than getting monarchy but CoL had much higher trading value. WK finaly took 3 techs for peace (25 BC), next turn I traded philosophy for CS and switched to bureaucracy immediatly. So 103 beakers per turn at 1AD, pathetic though not unexpected.
I got nearly everything I need from trades, selfteched only literature. GL was still available, only I and Charlemagne had marble at this time so I decided to try and build it. With some overflow from forge, 3 chops and 2 pop whip I finished it in 5 turns (50 AD

). With the GL and NE Heliopolis makes a decent GP farm city.
Also got some gold from trades, 220 failgold from the Parthenon. Planned to get some failgold from MoM as well, but as no one bothered with it I finished it myself. It's good to have a hammer-heavy capital, it can accidentally build some useful wonders.

I rsearched paper, started on education and halfbulbed it with the next GS. Still no one has paper and Mansa is researching engineering, looks like I have good chances to lib nationalism.
With a few chops Thebes can build Taj Mahal in ~10 turns. Heliopolis will produce another GP in 6 turns. If I start a GA with him then it will end at about the same time when the TM is built, i.e. 2 consequtive golden ages or 3 if I want to. Probably 4 if I can produce 5 GP's during 3 golden ages which is doable. That could be a game changer.
Until recently only civs in Judaism had theology, that is the Apostolic Palace is likely to be built by one of them. I decided to convert to Judaism, religious victory may be possible. Mansa is in free religion now (was Judaism), he's built Shwedagon Paya.
