About
About Lyonesse – Arthurian Drowned Land
Chivalric romance kingdom between Land's End and Scilly, home of Tristan, drowned 'single night' where 140 churches/churches razed – echoing Ys/Cantre'r Gwaelod template. Tennyson's Idylls and Thomas Malory codify. Cornish folklore preserves St Michael's Mount–Marazion causeway as Lyonesse remnant; real Isles of Scilly were once single island Ennor drowned incrementally (separate archipelago). No archaeology of kingdom; Isles intertidal field walls (Scilly) + submerged forest at Mount's Bay prove gradual Holocene sea-level change but not kingdom. Trevelyan / Lyonesse Project 2009–13 UK seas linkage studied.
Why it mattersIllustrates how Arthurian literature anchors itself to real inter-tidal archaeology; Isles of Scilly archaeology program disambiguates folklore from Holocene data.
