“There are known three lists of apkallus, two cuneiform and the one in Berossos. The first known cuneiform list of seven apkallus was published by E. Reiner in 1961, and then reedited with new pieces added by R. Borger in 1974.
Already Reiner suggested that the broken tablet belonged to the Neo-Assyrian incantations series Bīt Mēseri, “protected house.” Borger made clear that the list belonged to the third tablet in this series, and that there are traces of two more lists of a similar kind.
(E. Reiner, “The Etiological Myth of the ‘Seven Sages’,” Orientalia (NS) 30 (1961): 1-11. Borger, “Die Beschwörungsserie Bit Meseri,” 192-3.)
There are found two copies of of the apkallu list from Bīt Mēseri in late Babylonia. A. Cavigneaux published a tiny little fragment in 1979. In 1983, E. von Weiher published the transliteration of the full list as part of an Uruk recension of Bīt Mēseri.
The tablets were found in the house of what was most likely a priest specializing in astrology and divination. They can be dated to the 4-3 century, which means about the same time as Berossos wrote his Babyloniaca.
That there existed a Babylonian recension of the apkallu list in Bīt Mēseri is important, because it demonstrates that the tradition contained in this list was not an isolated Assyrian phenomenon.
As already stated, the Antediluvian King List from Uruk, W 20 030, 7, published by van Dijk in 1962, contained both seven kings and seven parallel apkallus. Berossos also paralleled kings and apkallus, but unlike the Uruk tablet it has one apkallu parallel to the first king, a=one to the fourth, four to the sixth, and one to the seventh.
The names of the apkallus and their successions are identical in Bīt Mēseri and the Uruk tablet, with small variations in spelling. We render the names in the Sumerian form they have in the Uruk tablet:
There is a correspondence to the Greek names in Berossos, but it demands both scholarly quibbling and a bit of creative imagination to explain how exactly the Sumerian words were transformed to Greek ones. We have to bear in mind that it is far from certain that we have Berossos’s own spellings. His text has gone through many hands.
In Bīt Mēseri the list of the seven apkallus is succeeded by a list of four apkallus and built into an incantation. For the sense of convenience we bring here an English translation based on Reiner’s English edition of a part of the list and Weiher’s German edition of the full list.”
