There are several historical figures that were not too far off inventing the steam engine however, al-Jazari was undoubtedly the closest, in the early 13th century...
A proto-industrial revolution with only al-Jazari's inventions is a possibility, he invented an early crankshaft in 1206 [1], he invented 5 machines to raise water alone (including the first suction pipes, suction pumps and most importantly, the twin-cylinder reciprocating piston suction pump [2]) and invented automated gates and doors (plus made loads of clocks and loads of other things).
So, my question is, what if Al-Jazari also incorporated his crankshaft and his extensive work on hydropower (albeit with steam) into inventing a prototype steam engine by 1210?

[2] This pump is remarkable for four reasons:

[2] This pump is remarkable for four reasons:
- The first known use of a true suction pipe (which sucks fluids into a partial vacuum) in a pump.
- The first application of the double-acting principle.
- The conversion of rotary to reciprocating motion via the crank-connecting rod mechanism.
- It was able to raise water 13.6 metres with help of delivery pipes
