Hairan II was a Palmyrene prince, the son of king Odaenathus and, possibly, his second wife Zenobia.
The existence of Hairan was established by the discovery of a lead seal (code named RTP 736).
[1] Odaenathus had another son, Hairan I, who appeared in different inscriptions dated from 251 AD onward.
[3] According to Henri Arnold Seyrig, Hairan II must be identical with Herennianus and he was an older brother of Vaballathus and did not reign.
[4] Andreas Alföldi also suggested that Septimius Herodianus is Herennianus; another seal associated with the seal of Septimius Herodianus represented a woman crowned with laurel leaf who, according to Alföldi, can only be Zenobia.
