GRICE E BONAVINO: LA SCHOLA LABRVM DEL TORELLO

 he north (  Fig. 88 ). 549  From here both the hot and probably also the cold water were conducted to the bath tub on the other side of the partition wall. 550  Since this wall between  l  and  20  is heavily restored, no remains of the pipes or even openings for them have survived. Whether these features were removed already in antiquity, either before the eruption or soon after it by looters or in connection with the excavation is unknown, due to the lack of reports. In corridor  h²  two concave and  parallel indentations from two round features such as pipes (diam. 0.04 m, preserved length 1.2 m) run in a north-south direction along the west wall at a height of 1.1 m with a slight downward incline (  Fig. 89 ). The form and dimension of these indentations indicate that they stem from two parallelly- placed lead pipes, running along the west wall of the corridor. Since the wall at both ends of these indentations shows modern repairs, the original length and the starting and end points can no longer be established. But since the repair to the south of these indentations covers the back side of the east wall of kitchen  l , it could be very probable that the pipes that made these indentations came from the boiler in front of the north wall of the kitchen and left that room through its east wall. The repaired area to the north corresponds to the rear side of the niche for the   schola labrum  (  Fig. 56  ). 551  To the north of this 0.95 m wide repaired area of the wall, no indentations can be found. Thus it seems probable that the supposed pipes led into  caldarium   20  in the niche of the   schola labrum  to supply this element of the bath with water as well.
