On the same block there is depicted one of three musicians, all of whom face in the reverse direction, towards the left. They are presumably taking part in another scene, not connected at any rate with the groups of worshippers. The one in question is a trumpeter, his instrument being a plain straight trumpet with expanding end.[613] His dress is the short tunic, skull-cap, and tip-tilted shoe. He wears an earring, and the pigtail is thick and conspicuous, ending in a curl well below the shoulder. The other musicians are found on the next block (_e_). The middle one is clad like the former, but his instrument is different. It is an inflated skin, into which he is clearly blowing, but no pipe is represented: we must suspect a drone effect, the invariable accompaniment of Oriental music.[614] The third instrument is again different, being a fine specimen of guitar, twanged, it would seem, by the fingers. It is attached by a cord to the waistbelt of the operator, and is decorated by loose ribbons which flutter from the end. On the last block (_f_) an ox is represented in outline facing the original direction. Two round objects accompany the scene, the one hollowed in the centre, the other a plain disk. Upon the back of the animal there is a load, the top of which projects. It is impossible to say what the motive of this sculpture was, but being prepared for a non-religious interpretation by the scenes which precede it, it may be explained as a beast of burden, bringing a load towards the building of the palace. Possibly the round objects represent the wheels of a wagon which could not be introduced owing to lack of space upon the wall, which here comes to an end.
