1725 (1): I agree with BH that getting Persepolis onto a four-turn warrior/settler cycle is worth a little trouble, so I send a worker to start irrigating its game tile.
1700 (2): Persepolis settler --> warrior, River Hills barracks --> spearman (later switched to Immortal).
1675 (3): Persepolis warrior --> settler.
1650 (4): We found Shiraz southwest of the gold hill.
1625 (5): Zzzz....
1600 (6): We discover Iron Working, and we have one iron. It's underneath River Hills, which is perhaps too much of a good thing, since now we can't build warriors to upgrade to Immortals.

At least we should be able to manage Persepolis more flexibly with the game tile irrigated.
Persepolis settler --> spearman, Arbela barracks --> Immortal.
1575 (7): Although I'm not exploring, a worker move reveals apparent coastline four squares roughly northwest of River Hills. It's possible that we're on a fat peninsula, connected to the rest of our continent only in the northeast.
1550 (8): Persepolis spearman --> settler.
1525 (9): We found Gordium in the southwest. It has three BG, one shared with Arbela.
Persepolis's second cultural expansion disturbs three barbs from the nearby goodie hut. Our developed tiles in the area are protected.
1500 (10): No contacts yet. This is either an excellent start, or a wretched one because we're alone on an island.
