 Roman conspiracy : John <unk> accuse Gallienus of the assassination . An interesting passage in the work of the Anonymus post Dionem speaks of a certain " Rufinus " who orchestrated the assassination on his own initiative then explained his act to the emperor who <unk> the crime . This story talks about Rufinus ordering the murder of an older Odaenathus out of fear that he would rebel , and has the younger Odaenathus complaining to the emperor . Since the older Odaenathus ( Odaenathus I ) was proved to be a fictional character , the story was neglected by most scholars . However , according to Theodor <unk> , younger Odaenathus is an oblique reference to Vaballathus ; Rufinus should be identified with <unk> Rufinus , the Roman governor of Arabia between 261 / 262 . The evidence for a Roman conspiracy is very weak and can not be confirmed .
