Pre turn 550 BC
Since you asked
here are some comments on your turns.
I hate to waste the forest chop (10 shields) on a worker that finishes next turn, so I switched it to a horseman. Ill send to Arbella so we can send the Immortal there to the south. The horseman will be our homeland defense. I thought about a temple, but decided we wont need it after the dyes get hooked up.
I switched some tiles to let Persepolis to work a mined grass NE of the fur and the mined BG (Bonus Grass). This lets Tarsus work a mined grass instead of the hill. Tarsus will now grow in 8 instead of 16 turns. Food is king and growth is key if you want to win at the high levels. People in forums call this Micro-Managing (MM for short), for max shields & food. Theyll say I MMd Persepolis & Tarsus. Some people love to do this, and are masters at it. Im decent. The other cities look good.
This is picky, but the tile 1 S of Antioch would have been a good tile to mine. Its in the city area of Arbela and Antioch. By mining this one, both cities can swap the tile back & forth as needed. Also Arbela has lower corruption, so you want to mine its tiles first. It wont matter in this game. In Deity every little thing adds up.
Making peace with Zulu was a very good choice. Let him fight with Babylon and weaken both civs.
I cant decide what to Research next. It depends if we want to go for the quick kill conquest as a monarchy, or get to Republic where we may have a tiny bit of war weariness in captured cities, and have to pause our war for a while. Ill stick with Lit and we can decide on our government after I Play.
Those trades sound okay to me.

Good call on the worker roading Gordium.
Id have built a spear in Arbela so we can get the offensive Immortal fortified there south to Pasargadae. Ill build a spear next to free up the Immortal.
On Regent (& monarch if you play well) you can out research the AI. The AI stinks at early naval landings, so one spear in each city is usually enough in the ancient age. Galleys have to stick to the land, so you can see them coming and shadow them with an Immortal if you are at war. If you are at peace, the galley is usually empty and just exploring. Ive never been sneak attacked via sea in the ancient age. You can always pop rush an Immortal in an emergency if a ship shows up out of nowhere and you are at war with that civ.
Move Immortal in Tarsus to the south. We dont need him up north.
Move Immortals from Susa towards the south.
The Immortal from Arbela moves towards the south.
Spear in Antioch moves to Arbela for 1 turn so it will not riot.
Rename Pasargadae Jeffville since I hate typing Pasargadae.
I wish the Aztecs had not built their cities so far apart. I guess they think we are on a huge map.

We need knights to cover all that ground.
Hit enter
Turn 1 530
Persepolis Horse spear
Horse moves to Arbela, and the spear back to Antioch.
Jeff FYI in Succession Games (SG) a lot of people do not like automatic go to commands It does not bother me, but its good SG etiquette to not use them unless they expire during your set of turns.
Barbs cannot find a place to land, so the Immortal moves south to free up some space for them
Found Bactra > harbor (80 turns

)
Worker is mining the furs. I hate having no water.
Turn 2 510
Gordium barracks Immortal
Turn 3 490
We have Dyes

Change Antioch to Galley for a little exploring of our future victims. We might get 2 shields out of here.
Turn 4 470
Persepolis & Tarsus swap a couple of tiles for 1 turn.
Persepolis Spear Settler due in 4. Then I think we go to war.
IBT
Montezuma wants Mapmaking. Forget about it. I figured he was bluffing.

Even so we are almost ready for war, and could have taken him. He does have Iron though. Cracking his capital will take some doing since it looks to be over size 6.
Turn 5 450
Traded maps around and got us 22 gold.
Lets declare war after we get Lit. We can build an embassy in Babylon and trade to get them in an alliance with us. Aztecs will have to fight a 2 front war. If the Aztecs get Zulu to ally with them its no bid deal, Zulu cannot reach us.
Check on the barbs, no camp yet, darn.
Jeffville has 9 Immortals, mr999 will get to go to war I think.
Drop slider to 80%, Lit in 4, 0 GPT. I want enough Gold to build embassies.
Turn 6 430
Barb ship finally makes a move to the dark area.
Turn 7 410
Turn 8 390
Persepolis Settler Immortal
Susa Immortal Immortal
Tarsus Immortal Immortal
Turn 9 370
Gordium Immortal Immortal
Arbela Immortal Immortal
The workers are drifting south so they can build roads when the war starts. There is one now building a road in the most southern tile not in Aztec lands. There is a stack of 10 Immortals on that tile. Two more get there in 2 turns.
Drop slider to 50% & still get Lit in 1.
Turn 10 350
We get Lit Code of laws. I think we can conquest in Republic is we get another 2 lux.
We can talk about it and change if you want to go Monarchy & fight the rest of the way.
Barb comes out of the only dark square left up north. Immortal kills barb, and can pop the hut next turn.
Babylon finishes the Pyramids. How nice of them to build that for us.

Well may have to raze some of the Babylonian cities because they will have too much culture. Except the Pyramids, we figure a way to keep that.
Build embassy in Babylon and Zululand.
Neither one wants to ally against the Aztecs, so it will just be us. Keep checking, after we raze a couple of cities and the power shifts they may say okay. By then though you may not want them in the war.
Mr999 you will have a fun time on your turns.
There are 11 Immortals on the tile S of the horse. There is 1 worker building a road.
Youll want to get 4 workers in a chain gang down there so they can road a grass tile each turn. 2 road, the other 2 move. Next turn 2 road, the other 2 move up. Keep them guarded with an immortal.
Declare war in the diplomacy screen before you move into Aztec lands so we dont take a rep hit.
Settler is on the dyes. Send him West so the barbs will keep building on the one dark square in the east peninsula tip.
I would pillage the Aztecs game & cow squares, and Iron before you attack the capital. Taking away the game and cow tiles might get them to size 6.
Arbela is building a horse. Leave the horse there and build 1 more. The second one is for Persepolis. We need 2 units in any city that can hit size 6 to keep it from rioting. We can upgrade the horse to knights later.
Tarsus is borrowing grass tiles from Persepolis. Be sure to give them back when Persepolis grows.
Score is 160. We have about ½ the power graph. Our culture is weak, but our culture is one of war.
Have fun
