Well played it and then found Mike P had posted some good advice which I had missed

the good news was I had worked it out myself
Turn 1
Check relations between FDR and Monty and surprisingly the relations are fine. Use this fact to let me trade Spices for Gems for an immediate boost to happiness. Rome is running 3

and this will help solve it, move the Archer from just south of the city to improve happiness again.
It is clear that Saladin is going down and we have no forces that havent move that could capture the city. So what do we do? we extract Techs out of him for Peace and then let Monty take him down (Some of Mike Ps superb strategic vision must be rubbing off!)
And yes he goes for it. Immediately switch to Org Religion for the building bonus
Do my usual bit of detail conscious MM, so come on what are we doing building a cottage here instead of the alternative Grassland Site?
Turn 2
Saladin pops his clogs
And we are tbhe nost cultured CIv out there.
Seville finishes: Forge
Rome finishes: Buddhist Temple
Medina finishes: Granary
Turn 3
HBR comes in and having snagged Calendar for me Machinery is definitely next, by the time it comes in we should have built a few Catapults ready to start on Macemen and push towards Conquistadors
Turn 4
We pop a great scientist (Plato if you are interested). He could Light bulb Philosophy but as wee already own the Holy City for Taoism

I despatch him to build an Academy in Rome which with its excellent commerce output can be another research powerhouse.
Turn 5
We need to watch HC, he has appeared with Long bowmen and demanding Alphabet (refused!) so he is a we bit miffed at us but as we are building militarily not really a threat.
Turn 6
Sufficient courthouses built to allow us to star a Forbidden Palace in Neapolis. As this is on our southern borders it will stop city upkeep going daft as we expand southwards. Start Seville onto the Colossus as it and others are working a few water tiles and it had nothing else pressing to build!)
Turn 7-10
A few Cats built and Buddhist Monks (on goto orders

) despatched to our southern cities to secure the 25% building bonus). Cumae is having its last two mines prepared and will be a real military powerhouse for us in the future. Our economy is still strained by the size of our empire so I am building some markets where it makes sense and spreading religion to help our economy. We need to pop a great prophet as we are giving away money not having our shrine built. Apologies for not spotting this earlier so I have done nothing about making it happen
Baghdads borders are in a culture war so I have prioritised culture buildings for it.
