Bricks appear to have been placed there to prop up the southern side of the bacino 17013 after it was broken. Westernmost brick is on top of fallen part of the broken bacino (fallen bits on this side of the bacino = SU 17061). This indicates reuse of the vessel after breakage.
Upon removal, bricks covered collapse similar to 17042 and, closer to the bacino, reddish soil with gravel - cut into collapse? placed on top?
