So it's my very first BTS succession game turnset, and I'm tasked with turning around this crazy indecisive civ to get our cultural victory back on track. The immediate priorities seem to be to claim the marble chokepoint, and I also like the location west of Madrid to claim a bunch more resources.
Research needs to go to Aesthetics, since there's wonders there and all sorts of cultural stuff up on that branch of the tree. I let all the cities continue on the inherited builds. On the diplomacy front, I sign Open Borders all around. I see no reason not to.
Now, I've got a crazy plan. I think I can just barely get the Parthenon done on my turnset.
If I triple-whip Madrid's settler right now, I can settle the marble city on my turn 6. It will expand to reach the marble on turn 16, which will take two workers to quarry up by turn 19, after pre-roading it.
Aesthetics will take 13 turns to research, then Granada can start building the wonder. Wang Kon has Mathematics and should trade it to us for Aesthetics, so we can get full chop value. Then it's just a matter of chopping six forests at Granada before turn 20. So I built almost nothing but workers out of our cities for most of my turnset.
===========
The barbarian city to the north turned out to be on a hill, with three archers, one of which is CG2. I'll just leave it there. I sent two axemen exploring past it (axemen actually make very good scouts, barbarian horse units are uncommon.)
Confucianism was FIADL, and so was the Temple of Artemis.
Roosevelt and Hatshepsut showed up on the contacts list!
Turn 6 (225 BC): The city of Cordoba is founded at the marble chokepoint, as planned.
Turn 8: A forest grows near Granada! I take this as the gods smiling on our Parthenon plan! And Judaism spread to our lands (in Granada). I converted - Hatshepsut and Suleiman are both Jewish too.
Turn 12 (75 BC): YES!
Judaism spreads to our marble city, which will now expand to the marble two turns sooner! And, this:
YES again! That's everything we need for the Parthenon.
I also swap Aesthetics to Roosevelt for Alphabet, and that lets me continue the brokering by flipping Iron Working to Suleiman to get Monotheism. I revolt right to Organized Religion, to get that building bonus in the Parthenon city. Then a turn later I finish off the brokerages by flipping HBR, Math, and Aesthetics to Elizabeth to pick up all of Meditation, Priesthood and Monarchy.
Research set to Drama, though it won't finish on my turnset and will surely get vetoed by some philistine.
Alexander demands Horseback Riding, and I let him have it.
Turn 18 (75 AD): The city of Toledo is founded southwest of Madrid, claiming copper, wines, sheep, crabs, and an oasis, and even counts as fresh water with the oasis.
And...
Shazam, just in the nick of time. There's some culture!
An overview shot:
Good news: we now have 9 workers, up from 2 at the beginning of my turnset.

We're also much better caught up in technology, though we still trail by Calendar and Construction. Hereditary Rule would be a natural to adopt right now; I didn't but the next leader probably wants to.
