Spoiler :
thank you for an interesting map.
I saved 2 ruins for t20, and one of them gave me 20 faith - free religious idols. Scouting till t30 told me that this is basically pangaea (and it was...) so I decided to go for SS and built stonehenge. I think I got 60 faith ruin later too.
cap BO: scout - monument - scout - granary - 2 archers - stonehenge - shrine/settlers - oracle - settlers
I stole a worker from Songhai early. And I killed/stole his settlers so that I could use all of nearby land for city spamming. I even citadeled him to get dye. Didn't take his cap, as I worried about warmonger penalty (and no open borders...)
oracle t83, reformation t86. Ethiopia choose glory (!!!) of god. I think I enhanced around t75 - pagoda and mosque.
Not sure this could be faster than domination (probably not).
