The pavement of room 1, like that of 3, is mortar (cocciopesto), containing isolated fragments of white and coloured marbles, including bardiglio scuro (or Hymettan?), giallo antico, and portasanta(?), amid a regular scatter of white chips, from 0.05 to 0.10 apart. A band of more closely spaced white tesserae, approx. d. 0.60 × w. 2.90 (tesserae from 0.005 to 0.008), marks the threshold between rooms 1 and 3. The three fragments of bardiglio scuro have maximum measurements of 0.20 × 0.125; 0.15 × 0.07; 0.06 × 0.065. Wall-paintings (Figs. 4, 5a; Pl. 133; Elia, 265; PPM ii. 231–2, figs. 2–4) State of preservation. The wall-paintings are late Third Style, with design and colours now damaged but with a few exceptions relatively easy to decipher. The W wall is the most complete, with plaster preserved to full height on the right, but dropping to just above the top of the dado near the left end before rising again to half-height in the SW angle. On the E wall, decorated only to the right of the doorway to room 2, the plaster is well preserved to mid-height. The S side of the room is open to room 3, but the shallow responds at each side retain plaster to mid-height. The N wall has no decoration other than fragments of a lararium painting to the right of the street entrance. The plaster overlaps the pavement. West wall. The DADO (ht. 0.82) is black with a delicate design of white and yellow lines, focused on a series of four little panels containing decorative motifs, one beneath each of the intervals of the main zone. Within an overall frame formed by a narrow white base-line (0.15 above the floor) and vertical white lines at each end (0.07 from the left angle, 0.19 from the right) the space is divided into five parts (w. resp. 0.70, 0.95, 1.17, 0.92, and 0.72) corresponding to the fivefold structure of the main zone. The two central divisions are each effected by a vertical white line interrupted at mid-height by a tiny square tilted at 45º; this is framed by the same white line, with an inner border-line in yellow, and contains a central rosette in white.
