Forbidden Temple

[Absinthe]

I have no idea what I am meant to do, I have gotten so far as to getting up to the spikes just before you enter that room with a magical ritual circle thing on the floor with a column in the middle of it but I keep coming across either a switch which is blocked by spikes or stuck switches that won't move and I am unsure what to do next. Help please?
