On both the southern and northern walls, only the black underdrawings have been preserved. On the southern wall, the painter used a brush approximately one centimetre thick to outline the figures, of which only two heads remain visible. The faces are elongated and presented frontally, featuring long, almost horizontal eyebrows and slightly semicircular, large eyes with black irises. Long, straight noses protrude from both eyebrows, but none of them have been preserved in their entirety. The lips are outlined by two parallel lines, while a small beard is also defined with a short line. Many of the lines have been retouched. A black underdrawing was also used on the northern side: with quick strokes, equestrian figures of kings were drawn, and two of these still survive. We can make out swift, decisive strokes and a few corrections, for example on the belly of the first horse. The face has only been preserved in the case of the left figure: it is outlined very schematically, with a round head and merely implied eyes. The figures are slender and fashionably dressed. The two mural paintings are definitely separate: the one on the southern wall is older, while the one on the northern wall is more recent. This is also evidenced by the composition of the plaster and the black colour.
