Here's the scene from the party's point of view. You have intiative. The orange is the trough, the yellow the bed of hay, the gray line is the stone image and the black and white square the abacus. The water trough is between the abacus and the image.
Please take whatever action you deem appropriate. The Minotaur is moving towards the wall to get either the sword or the axe as you gain first attacks.
