The religious traditions documented in the Kalevala oral poetry represent this period, though the surviving written attestation comes later: Mikael Agricola's 1551 deity list is the earliest written primary source, and Elias L\u00f6nnrot's 1835/1849 Kalevala compilations are the main documentary corpus. The oral runo-song tradition preserved in the Kalevala is estimated to reflect religious practices from the Iron Age through early medieval Finnish/Karelian culture. Pentik\u00e4inen (1999) is the standard scholarly reference for this period's religious content."]], "columns": ["period_id", "tradition", "period_name", "start_year", "end_year", "notes"], "primary_keys": ["period_id"], "primary_key_values": ["PER_FINN_TRADITIONAL"], "units": {}, "query_ms": 2.530060999561101, "source": "jebboone/deitydb", "source_url": "https://github.com/jebboone/deitydb", "license": "MIT", "license_url": "https://opensource.org/licenses/MIT"}
