Paganism/Heathenism are big umbrella terms that also encompass buddhism and its sects.
The greco-romans actually traded and dialogued with buddhists even hellenized the religion in some centuries.
So for those looking to reconstruct paganism by looking at runes or Odin myths don't worry, buddhism is still a pristine and complete pagan "path" to practice.
>As Buddhism expanded in Central Asia and fused with Hellenistic influences into Greco-Buddhism, the Greek hero Heracles was adopted to represent Vajrapāni. In that era, he was typically depicted as a hairy, muscular athlete, wielding a short "diamond" club. Buddhaghosa associated Vajrapāni with the deva king Indra.[13] Some authors considers that the deity which is depicted is actually Zeus, whose Classical attribute is the thunderbolt.[15]

Really buddha embodies the highest form of the pagan solar ideal, warrior ascetic mode.
