SUMMARYFire-swords, burning mirrors and airships (Nov 6, 2026; 11 images from Tito). Record: the "17th-century electric swords" engraving (KDSH blog) is the Nuremberg peace fireworks of July 14, 1650. Its own cartouche reads "Eigentlicher Abriss des Feuerwerks Schlosses... 14 Julii Anno 1650": fire-swords, fire-wheels and spark fountains at the banquet ending the Thirty Years' War. The caption says fire (fireworks), not electricity. Record (twist): Otto von Guericke built an electricity-making sulfur-ball machine about 1663. BURNING MIRRORS: Disputed as used at Syracuse (212 BCE). Polybius, Livy and Plutarch are silent on mirrors; Lucian (2nd c.) and Anthemius of Tralles (6th c.) tell it. Tests: Sakkas (1973) about 70 mirrors at about 50 m lit a model boat; MIT (2005) lit a still hull at about 30 m; MythBusters failed on a moving ship. Record: Cavalieri's Lo specchio ustorio (1632) on burning-mirror geometry; Parigi's Uffizi fresco (about 1600). AIRSHIPS, Record: Blanchard and Jeffries crossed the Channel by balloon (Jan 7, 1785). Robertson's La Minerve (1804), a design for a 60-person world airship with decks and cabins, never built. Pattern: sun-power and flight machines drawn and tested in Europe while older sun and sky knowledge elsewhere was called myth. Added 5 rows to oldtech (85).
