Shalmaneser V
Shalmaneser V is also known by the name Ululayu, meaning "one who (was born) in the month Ulūlu". Several non-contemporary sources, such as the Ptolemaic Canon, the Babylonian King List and the works of later Greco-Roman historians, use this name, or a variation thereof (such as the Greek ) in place of his actual regnal name. This has historically been interpreted as Ululayu having been a second regnal name of Shalmaneser, but while the name also appears in a handful of contemporary sources, letters sent by Shalmaneser when he was the crown prince to his father Tiglath-Pileser, these are not formal documents. There is no evidence that contemporary official documents ever referred to him as Ululayu. There is also no evidence that any other Assyrian king ever used more than one regnal name in their lifetime. Nevertheless, Shalmaneser V was evidently remembered by later generations by the name Ululayu, which, going by the context in which it was used, might have been his birth name.
