Water fixture?


Earlier this season, we published a photo of a plastered basin in the north colonnaded building.  In the northeast corner of this room is another water feature, plastered and half-round fed by a water pipe.  Its function is a mystery, in part because we have not yet reached the bottom of the feature.


Christine discovered the feature and below she is seen inspecting and clearing the water pipe.  Ideas anyone?
