The Neo-Assyrian prophecy corpus is extant on two kinds of clay tablets, which differ from each other both in size and in shape. Texts 1-4 are relatively large, vertical tablets containing several oracles in two or three columns. Nos. 5-8 are smaller, horizontal in shape and contain only one oracle each (see diagram on p. LIV). By its format, no. 9 belongs with nos. 1-4, although it contains one oracle only; for nos. I 0-11 see below, p. LXIf. All the tablets display a fixed length ratio between their horizontal and vertical axes, which remains constant even though the individual tablets vary considerably in size. In the horizontal tablets this ratio is 2:1 (that is, the width of a tablet is twice its height), whereas in the vertical ones it is 1:2 or 2:3, depending on the number of columns into which the tablet was divided.
