Is My Poseidon Based On Greek Mythology?

The question about the origins of 'my Poseidon' points towards a character that's likely a modern reinterpretation, but I'd need the specific title to give a precise breakdown. Within the vast world of fictional sea gods, you're probably encountering one of two distinct types. Some stories directly lift the figure from the Greek myths—the volatile god of the sea, brother to Zeus and Hades, wielding his trident and known for his temper. This version carries all the classical baggage: the contest for Athens, the creation of horses, his disputes with Odysseus. If a novel or series labels him as 'Poseidon' and sets the action in a world with Zeus and Mount Olympus, then it's squarely based on the mythological framework, using that established lore as its foundation. However, there's a whole other category where 'Poseidon' is essentially a title or a mantle worn by an original character. This is common in urban fantasy, paranormal romance, or original mythopoeic fiction. The author might create a completely new pantheon or a hidden society of oceanic deities where the ruler is called Poseidon, but his personality, backstory, powers, and relationships are freshly invented. He might be a CEO of a maritime corporation, a broody immortal living in modern-day San Francisco, or a deity in a fantasy kingdom with no connection to Greek Athena or Hera. In these cases, the name is a powerful archetype the author is evoking, but the core being is an original creation. To figure out which one you've got, look at the surrounding world-building. Are other Greek gods like Apollo or Hera present and named as such? Does the story reference classic myths directly in its plot? If yes, it's mythology-based. If the world has its own unique system of gods, even if they have vaguely familiar domains like 'sea' or 'storms,' then your Poseidon is likely an original figure using a famous name as a shorthand for his domain. Either way, the fun often lies in seeing how the author plays with or departs from those ancient expectations. My hunch, given how common reinterpretations are these days, leans towards it being a fresh take unless the book is explicitly a retelling.

Man, the protagonist thing in 'My Poseidon Story' is trickier than I expected. For a long while, I was convinced it was Leo, the guy who narrates most of it and whose summer vacation gets hijacked by mythological chaos. But the more I reread, the more it feels like the story is actually shared between him and Marina, the marine biology intern he meets. She's the one with the actual connection to Poseidon's legacy, and her choices drive the last third of the plot. Leo reacts; she acts. Makes you wonder if the book is playing with the idea of a dual protagonist setup without making it obvious. I've seen some heated forum threads about this. One convincing take argued that the real protagonist is the coastal town itself, with Leo and Marina just being lenses we see its transformation through. Not totally sold, but it's an interesting angle.

Sure, the Poseidon books weave in plenty of Greek myths, but they're not a straight-up retelling of ancient events. They take the core idea of Poseidon and his world—the trident, the underwater kingdom, the rivalry with Zeus—and build a whole modern fantasy story around it. It's more like using mythology as a really rich playground for new plots and character conflicts than a history lesson. I think what they do well is keep the 'feel' of the myths, the grandeur and the godly drama, while making the characters way more relatable. The books explore Poseidon's relationships with his children, like Percy Jackson, and other gods in a way the original stories never really did. So, based on real mythology? Inspired by, absolutely, but the events themselves are the author's own spin on that ancient foundation.

Just finished a deep dive into Rick Riordan's 'Percy Jackson and the Olympians' series, and what strikes me most is how Poseidon's role isn't just a god on a throne. It’s about his messy, complicated relationship with Percy’s mom, Sally Jackson, and his half-blood son. That whole setup explores themes of divine neglect and the burden of legacy in a way that’s painfully human. The books use Poseidon’s domain—the sea—as a metaphor for emotional chaos, hidden depths, and unpredictable change, which mirrors Percy’s own turbulent adolescence. Beyond Riordan, there's a lesser-known novel called 'The Sea of Monsters' (the second book, obviously) where Poseidon’s nature is central. It’s not just about storms and tridents; his children are portrayed as outsiders, caught between worlds, which directly tackles the mythic theme of the gods’ dangerous favor. The way the narrative handles prophecies tied to Poseidon’s line also interrogates the idea of fate versus free will, a core tension in so many Greek myths.
