Oracle slingshot to...

[Kiershar]

My personal favorite is to race to machinery with Qin Shi Huang to get Chokonu.

AnimalHusbandary and/or bronzeworking, Wheel, Mysticism, Meditation, Priesthood
Build a settler before priesthood
Build Oracle asap while reasearching pottery
Pick Metal Casting
Make forge in 2nd city (whip+chop, ~10turns window)
Run engineer in forge city
Make 2-3 others city, improve only food and hills; research ironworking+archery
Lightbulb machinery when Great Engineer pops (200-100ish BC)
Make a bunch of Chokonu
Overrun someone in 1AD - 100AD

Very powerfull rush imo

My record is Biology. (A challenge map and I don't think I was the only one to do this. Liberalismed Medicine next turn for enviromentalism.)
