By the Hellenic era, Greek awareness of Osiris had grown, and attempts had been made to merge Greek philosophy, such as Platonism, and the cult of Osiris (especially the myth of his resurrection), resulting in a new mystery religion. Gradually, this became more popular, and was exported to other parts of the Greek sphere of influence. However, these mystery religions valued the change in wisdom, personality, and knowledge of truth, rather than the exact details of the accepted myths on which their teachings were overlayed. Thus in each region that it was exported to, the myth was changed to be about a similar local god, resulting in a series of gods, who had originally been quite distinct, but who were now synonymous with Osiris. These gods became known as Osiris-Dionysus.
