I have seen a remark about how Apollon shouldn’t be represented with yellow hair because ethnic Greeks were not blonds. The thing that bothers me about this remark is this, the gods are not human. The way the gods are envisioned poetically is based on symbolism, and so is how the god is expressed. It has nothing to do with human genetics. To say that a goddess has eyes the color of the sea, this obviously has symbolic connections. Well then Apollon’s coloring has nothing to do with racial identity, but rather on symbolism. Gold is the color of the divine, Apollon is the guardian of the process of attaining deification connected to his association as guardian with Dionysos, as guardian of the vine. As a god intimately connected with deification in the mysteries, the divine hero, it is natural the god who be expressed specifically as one with gold hair. We know he has gold hair from poetry, and even the remains at Delphi have the god… quite literally… with gold for hair. So why should worshippers throw away this very real material about how people saw the god away. Now a mythic representation where the god is disguised as a mortal, I can see making him appear ethnic for those reasons, because he is literally taking the form of the people with whom he is blending. However, for religious representation of the god it is reasonable to depict the god with symbolic poetic descriptions. He is the god of light, he is bright. He is golden thoroughly. For these reasons it is quite appropriate to portray the god with golden hair, despite ethnic origins of his worship. And that is saying nothing for those who discuss parts of his cult that are connected to the north and the Hyperboreans.
