Ahti was the Finnic god of the sea, of fishing, of the abundance of the waters. He was sometimes confused with Lemminkäinen (Ahti being also used as Lemminkäinen's epithet in some folk-traditions; the two figures are sometimes treated as one and sometimes as quite distinct, depending on the source-tradition). As a sea-god, Ahti dwelt with his wife Vellamo (a goddess of the waters herself) in their hall beneath the waves; fishermen invoked him before going out, and large catches were attributed to his favor. The cult-tradition included specific charm-songs to be sung at the launching of boats and the casting of nets, of which a number have been collected from oral tradition.
Curator’s note
What the sources say, and what later tradition added. The sources for this bay
The principal source is the Kalevala (where Ahti appears principally as a sea-figure) and the collected fisherman's charms in the various ethnographic collections. The relationship of the sea-god Ahti to the warrior-figure Lemminkäinen (whose secondary name is also Ahti) is one of the unresolved questions of Finnic mythological scholarship; the two may be originally distinct figures conflated by oral tradition, or one figure with two aspects.

- 2nd–1st millennia BCE
- Indo-European language dispersals and regional Bronze Age cultures provide a remote comparative background, not a recoverable common canon.
- c. 500 BCE–1 CE
- Iron Age material culture, names, sanctuaries, and classical ethnography offer early but external evidence for Celtic and Germanic religions.
- 1st–4th centuries CE
- Roman inscriptions and provincial cults preserve many Celtic, Germanic, and local divine names.
- 4th–8th centuries CE
- Migration-period and early medieval conversion transform ritual institutions while heroic traditions continue.
- 8th–11th centuries CE
- Viking Age poetry, runic evidence, archaeology, and Scandinavian conversion form the core context of Norse myth.
- 9th–12th centuries CE
- Slavic, Baltic, and Finnic traditions enter chronicles and missionary accounts, often through hostile observers.
- 11th–14th centuries CE
- Irish, Welsh, and Icelandic manuscripts preserve major narrative corpora in Christian literary environments.
- 12th–16th centuries CE
- Saxo, saga compilers, Baltic chroniclers, and later antiquarians systematize or reinterpret older material.
