Ok, there are a number of ways of doing this. The most often used one id to actually force attack each of the golems in turn, so you only have one to deal with at one time. The second is to cast sanctuary on a character and just walk over to the statues and grab all of the stuff. Also, Hide in shadows can work. Try this: Walk up to one of the tatues and 'open' it. Now, pause the game and buck up the desired item, before licking on your character again and pressing the hide button. Result: item stolen from one statue, and one hidden thief who can leisurelly leave the room
. Hope this help you out a bit, there are other strategies etc., but the first one is, IMHO, the easiest and probably safest.
