No early record yet
Our sources do not yet include an early text or object that describes Ayudha Puja, so we give no date for its beginning. What we can show is a living custom, described below.
To verify: An early text or inscription that describes the worship of tools at Navaratri; Early descriptions cited by Wikipedia that we have not read: Bartholomäus Ziegenbalg’s Genealogy of the South-Indian Gods (English edition, 1869) and F. Kittel’s Kannada–English Dictionary
