The older name for topology was "analysis situs", analysis of place.  Why 
that was changed is unknown to me, but the topo- root is just Greek for 
place and it would be a stretch to assume anything else without good 
evidence.

A French mathematician named, IIRC, Jean Pont wrote a book called, 
"L'Histoire de la topologie algébrique avant Poincaré" that traces 
topology, at least algebraic topologie to Euler's solution to the bridges 
of Königsberg problem.  I think V-F+E = 2 came next.
