Labels again were made of clay: two small clay labels (Brit. Mus. K. 1400, K. 1539) give us the titles of two series of astrological and omen tablets; while another (K. 3787) gives us the name of Khipa, a female slave; it is dated in the 11th year of Marduk-aplu-iddina, i.e. _circ._ 710 B.C. There are miscellaneous clay objects which do not properly come under the heading of terra-cotta figures or clay bas-reliefs, and therefore may be mentioned here. Sometimes clay squeezes or impressions were made of early inscriptions; an excellent example of such squeezes was acquired some years ago by the University of Pennsylvania (cf. Fig. 3);[47] it is a squeeze made by a Neo-Babylonian scribe of the sixth century B.C. of an inscription belonging to Shar-Gâni-sharri, king of Akkad. The characters of course are raised in relief and read backwards. Allusion is elsewhere made to the clay brick-stamps with which Babylonian kings were in the habit of inscribing their building bricks: an interesting specimen of a clay brick-stamp is seen in Fig. 4. It is a fragment of a stamp belonging to Narâm-Sin, the son of Shar-Gâni-sharri. The characters here are of course in relief and reversed as in the case of a seal. Another clay object of exceptional interest is seen in Fig. 5; it is a clay covering made by order of Nabopolassar, king of Babylon 625-604 B.C., for the preservation of the stone tablet of his predecessor Nabû-aplu-iddina (_circ._ 870 B.C.). It was presumably during the course of his work at the restoration of the temple of the Sun-god at Sippar that he alighted upon this early tablet. The clay cover bears an inscription of Nabopolassar on the reverse side and records the various offerings he deposited at the shrine of the Sun-god. The cover itself was found in a baked clay box, also preserved in the British Museum, and probably belonging to the same reign. Clay was further employed by the sculptor for tentative sketches, and by the stone-inscriber for rough drafts. Thus the sculptor to whom we are indebted for the portrayal of Ashur-bani-pal, king of Assyria, spearing a lion, sketched out his picture in clay preparatory to chiselling it on slabs of stone, and his original sketch is still extant (cf. Brit. Mus. 93011), while we can still see two rough drafts on clay of epigraphs inscribed on Ashur-bani-pal’s bas-reliefs (cf. Brit. Mus. Sm. 1350 and K. 4453 + K. 4515). CHAPTER V—ARCHITECTURE
