Here are 15 turns' worth of Persian development:
Inherited turn: I was considering not building a granary, but we're doing a forest chop that will be wasted if we keep building the settler. Persepolis swapped to granary.
2950 BC (2) -- The Americans already have a second city.
2710 BC (7) -- Persepolis granary -> settler.
2550 BC (11) -- Iron Working discovered. There are no fewer than three iron sources within easy reach of Persepolis. As it turns out, we discovered Iron Working at the same time as the Celts. I start research on Mysticism, which the Americans have at monopoly.
2510 BC (12) -- Persepolis settler -> warrior.
2430 BC (14) -- Pasargadae founded; Colossus immediately begun. Persepolis warrior -> settler.
2390 BC (15) -- Ooh, the Americans have a worker for sale!

We can buy it for Iron Working + 2gpt + 8g. However, I will leave this to the next leader; I also don't know if Amirsan thinks this is exploitative. If this trade is acceptable, I think we should take it at once, to make it harder for the Americans to build an early wonder.
Notes to the next leader:
* Our warriors are still scouting. No other civs have been found on my turn.
* Our solo worker is currently improving in the direction of Pasagardae and its wonder build. I would not chop any of the forests near Pasargadae now; Pasargadae could use them for shields.
* Persepolis is one of our best sites for building a wonder. I suggest building two more settlers, and then starting the Pyramids; if we wait much longer we risk getting beat to them.
* I think we should discourage research down the Writing -> Literature/Map Making path -- this will reduce the probability of a cascade to the Great Library or Great Lighthouse. It will, however, delay our cheap libraries.
* Here is my suggested dot map:
My suggestion is to found in rainbow order: red, orange (right on top of iron), yellow, green, blue (which probably should be shifted 1 north). Red, orange, and yellow are all fresh water cities and all claim iron for Persia's exclusive use.

If I were playing this solo under these rules, I would buy the American worker, found on red dot, then orange dot, then start building the Pyramids in Persepolis; I would have red dot and orange dot produce our workers/settlers/military while our wonders complete.
Good luck to our next leader!

EDIT: I just realized that we should probably bump orange dot one square southwest. We'd have to build another city to claim the ivory near that lake; however, moved orange dot has the advantage of significantly reduced corruption. Red, orange, yellow, and green dots, along with Pasargadae, would then all be the same distance from Persepolis (as Civ 3 distance is not Pythagorean). Since we can fairly easily make a mini-RCP layout here, I think we should do so.
