Cross-pantheon comparison
Sea gods compared across eight traditions
Poseidon, Njörðr, Enki, Varuna and Manannán are all filed under the sea, and no two of them are doing the same job.
Sea gods, river gods and the powers of the deep — kept apart here, because a tradition can have one and not the others.
Tap any two names to compare them. 40 figures across 8 traditions hold this office on this site.

What this office actually is, tradition by tradition
The sea is the clearest case in this whole encyclopedia of one English word covering several unrelated offices. Poseidon is the sea as a hostile power — a god you sacrifice to so that he leaves you alone, whose other great domain is the earthquake, and whose relationship with sailors is mostly adversarial. Njörðr is almost the opposite: a Vanir god of the profitable coast, of harbours and fishing and wealth from the water, married unhappily to a mountain-dwelling giantess precisely because the poem wants to contrast the two landscapes. Calling them both a sea god is true and tells you nothing.
Then there is fresh water, which several traditions separate sharply from salt and which English does not. Enki's domain is the Abzu, the body of sweet water under the earth that wells up in springs and rivers; his cult city Eridu sits in the marshes and his cleverness is a water-god's cleverness, seeping around obstacles. Varuna's history runs the other way — in the Rigveda he is the great sovereign of cosmic order who binds oath-breakers, and only in the later classical material does he settle into being the god of the waters, a demotion that the Vedic-to-Puranic shift performs on several gods and that is one of the most important structural facts about reading Hindu material.
The equation people most often reach for here is Poseidon and Neptune, and it is the one worth being most careful about. Neptune was an Italic god of fresh water, with a festival in the parched heat of late July that makes sense for springs and no sense at all for the Mediterranean; the sea and the horses and the trident arrive with the Greek identification. Where a tradition genuinely has no major sea god the tool says so rather than promoting a candidate, and Egypt is the striking case: a civilisation entirely organised around one river treats the Mediterranean as a foreign edge, and its water gods are Nile gods.
How the grid above was built
Nobody decided by hand who belongs on this page. Each figure’s entry carries a list of what the ancient sources named on that page record them as governing, and a figure appears here when one of those phrases falls inside this office. Their own wording is printed beside the name, so you can check the filing rather than trust it. Tapping any two names computes what the two figures actually share — and whether any ancient writer ever equated them, which is a different question and usually has a different answer.
Where a tradition is absent from the grid, no figure in this encyclopedia holds this office in it. That is a statement about eight bodies of surviving material rather than a gap in the research: several traditions genuinely have no god of a given thing, and saying so is more useful than promoting the nearest approximation into a column so the table looks complete.
The other eleven offices with a page of their own: War gods, Gods of wisdom and writing, Smith gods, Love and desire gods, Harvest and fertility gods, Healing gods, Moon gods, Messenger gods, Gods of justice and the oath, Gods of magic and prophecy, Fire gods. The full tool, with all 29 offices, is at the cross-pantheon comparison, and the pairings argued out at length in prose are in the written comparisons.
