The cuneiform bad, bat, be, etc. sign is a common multi-use sign in the mid 14th-century BC Amarna letters, and the Epic of Gilgamesh. In the Epic it also has 5 sumerogram uses (capital letter (majuscule)). From Giorgio Buccellati (Buccellati 1979) 'comparative graphemic analysis' (about 360 cuneiform signs, nos. 1 through no. 598E), of 5 categories of letters, the usage numbers of the bad sign are as follows: Old Babylonian Royal letters (71), OB non-Royal letters (392), Mari letters (2108), Amarna letters (334), Ugarit letters (39).
The following linguistic elements are used for the bad sign in the 12 chapter (Tablets I-Tablet XII) Epic of Gilgamesh:
sumerograms:
The following usage numbers for the linguistic elements of sign bad in the Epic are as follows: bad, (0 times), bat, (61), be, (16), mid, (7), mit, (8), sun, (1), til, (11), ziz, (8), BE, (2), IDIM, (2), TIL, (1), ÚŠ, (2), ZIZ, (1).
Instead of a large horizontal, as seen in the (digitized form, but one type of "bad") , the sign is seen in the Amarna letters as composed of two opposite facing (triangles), the wedges. It can be seen here [1], Amarna letter EA 153-(lines 153:4, 11), for "King-Lord-mine", "LUGAL, Be-li-ia", or Be-lí-ia", where "bēlu" is Akkadian for "lord".
