Was messing around one day and popped a few techs. Well just after the AD's I had rifles and artillary. The trick was to get a few cities up quick and some libaries and monuments. So for the techs I would got Pot, Writing, then make my way up to gunpowder. After GP I would use my 3 scientist (Run speasialist in your libaries to generate the scientist) to pop tech and use my policy points for rationalizm and on the left side of the tree get the 2 free techs.
Now that is 5 techs all popped at once and you go in to the renaissances and industrial era in one turn, this is around 500 AD or before all with NO wonders.
