- Basler Chroniken VI (1902) pp. 189, 226–227: Bernoulli moved the St Vitus notice from 1518 (manuscript "Anno XVCXVIII") to 1418 on Schilter's authority. Text confirmed.
- Reuss, Imlin'sche Familienchronik (1875) p. 26: "in 4 wuchen wurden ir mehr dan 200 dantzet". Confirmed 200.
- Martin 1914 p. 119: prints Imlin after Witkowski 1879 with "mehr denn 400 Dantzer" (note 2: Witkowski). So 400 is Witkowski's reading; Reuss, editing "nach der Originalhandschrift", has 200 (both printings). The independent Duntzenheim/Schad line has "more than 200".
- Schilter 1698 pp. 1087–1090: §II "Allein im Jahr 1418 ..."; Instruction "Veneris post Magdalene &c. XVIII"; minutes of "Fritag post Marie Magdalene"; §III verses from "Chron. MS. Argent. p. 318" headed "St. Veits Tantz An. 1418": "Viel hundert fiengen zu Straßburg an ...". Confirmed.
- Kleinlawel 1625 pp. 130–131: 1517 stanzas "Thewrung" and "Sterben"; 1518 stanza "Ein Seltzam sucht ... Viel sind Todt drüber blieben". No "Viel hundert" verses. Confirmed.
- Rem, CDS 25 (1896) p. 88: "Anno dni. 1518 im sumer da kam es zů Straspurg fast vil leutt sant Veitz tantz an, daß ain tag wol bei 15 menschen ankam. es weret fast lang, also verbott man das tantzen und pfeiffen und paugkenschlagen." Confirmed: "15 in a day" is an incidence, not deaths.
- Reuss, Specklin Collectanea, BSCMHA XIV (1889) p. 308, no. 2216: "über 100 zu Strassburg auff einmal tantzten ... Viel tantzten sich zu tode ... creutzle und rothe schuh ... schelmenwerk". Confirmed.
- Dacheux, Annales de Brant, BSCMHA XV (1892) p. 239, no. 3443: "um Margarethen ... uff fünfzig personen ... bis Michaelis ... 30 sch. pf. ... kein brucken schlagen ... mit saitenspiel". Confirmed.

## Calendar (computed, Julian; script code/calendar_1518.py)
- Easter 1518 = 4 April (Sunday) ✓; 22 July 1518 = Thursday ("5a Mariae Magdalenae" ✓); 23 July = Friday ("Fritag post Marie Magdalene" ✓); 25 July = Sunday; 2 Aug = Monday; 11 Aug = Wednesday ("4a post Laurentii", Lawrence 10 Aug = Tuesday ✓); 31 Aug = Tuesday ("Dienstag post Adolphi", Adelphus 29 Aug = Sunday ✓); 29 Sept = Wednesday.
- Grotefend, Heiligenverzeichnis (online, manuscripta-mediaevalia): "Margarete virg. et mart.": 13 July in most German dioceses; **15 July: Basel, Chur, Konstanz, Lausanne, *Strassburg**; 20 July Rome/France/England. "Adelphi (Adolphi) ep. Meten.: Aug. 29: Basel, Metz, *Strassburg." Maria Magdalena 22 July everywhere; Michael 29 Sept everywhere.
- Hence "um Margarethen" (Extractus) = about 15 July in Strasbourg usage; Imlin's "acht tag vor S. Maria Magdalena" = 14 July. Onset 14–15 July 1518.

## Open items
- Witkowski 1879 (Allg. Zs. f. Psychiatrie 35) not on archive.org (vols 33, 36, 38 are); the 200/400 variant therefore rests on Reuss vs Martin's report of Witkowski.
- "pfrymen" (1 pfennig "zu pfrymen" per sick person at the altar): unexplained; Martin: "Bedeutung unklar"; ElsWB has a lemma "Pfriemen" (awl) but the ritual sense is not established.
- "von Sanct Martzolff beladen": Martin glosses "[Epilepsie]".
