Oh sorry Uncle, the constant golden age for Persia was posted by somebody else so they get the credit.
Anyway, Persia's UA is 50% longer golden ages and combine that with Chichen Itza you now get double golden ages. As soon as you get Chichen Itza pop your first or second golden age (through happiness manipulation if you can do it but if not then use a saved great person). Then go for the Taj for another 50 turns of golden age and you'll have plenty of time to get things just to keep feeding it like the Louvre for two free great artist which give at a MINIMAL 12 more turns (3 turnsx2 lengthx2 artist). You'll get to a point where you look up top and see Golden Age 82 turns or some crazy crap like that. At this point you will run away with the game in terms of whatever it is you want to do. Go to war (all your units move 1 extra space and you can buy an army or out tech the computer by building more cities and buy the happy buildings since pop=science). Just be careful if playing a multiplayer game with friends and one of them is going for a 3 city culture win, you will have to eliminate that player (just our produce him in military).
Basically Persia's UA with Chichen Itza gives you the clear cut advantage in production and money so you can make a larger empire (just buy a colleseum in each new city you found and this in turn gives you more population=more science excluding Babylon of course).
