OK, I give up.
I read the hint book. I know to throw the levers highest to lowest.
The levers in the east room and upper right room look to be the same height. I start with east room, no gargoyles attack. I go to upper right, gargoyle attacked, therefore I assume that ain't the 2nd one. No matter what order I try (I can throw east, then lower right, then lower left, then west and not get attacked. Any lever I throw afterwards gets me attacked) fails.
I left that level (took stairs down, I assume that will "reset" the levers). I come back, throw upper right first, I get attacked.
At this point someone needs to tell me exactly which order to pull the levers.
Gods, I hope there aren't any more of these silly "pull lever/push button in the correct order or you die" puzzles.
Thanks in advance.
