[EoW][FARON TEMPLE] where was the hint for this puzzle?

I have been trying to play this game without guides and I was stuck on this puzzle for awhile, at first I thought I was missing a summon maybe that could interact with the statues in some way and after a hour of searching thinking I wasn't meant to be here yet I decide to look up the solution and the solution is that you need something to hit the switches at the same time. I thought the game was broken or something. Was there a hint that I missed or something?
