The clues are there by the unique descriptors of two of the required items, the unique name for one of the items, and then just a nearby item.
Top: Book of Immaculates II (near the fallen bookshelf in the area)
Right: Bucket of Water (need to press a switch to open a hidden passage to find this)
Left: Heavy Barrel (down the staircase passageway just next to it)
Bottom: Broken Vase (from nearby)
