We show that a trivial case of Janelidze's categorical Galois theorem can beused as a key step in the proof of Joyal and Tierney's result on therepresentation of Grothendieck toposes as localic groupoids. We also show thatthis trivial case can be used to prove the general categorical Galois theoremby using a rather pleasing technical result about sliced adjunctions.
