Doctrina illuminans: dasz ist das Liecht aller Lichter, oder die Lehr Winandi welche von Anstaig bisz zum Endte fideliter, parabolice tamen zum Chimischen Arbeith verleichtet... Illustrated with 19 water-colour symbolic drawings (ff. 25v-34v), in the first section, and 7 pen-drawings of alchemical furnaces, etc. in the last section (ff. 23-28). The first section (6 ll.) is headed: 'Von der weissen und klugen Mercurio'. The heading of the next section (40 ff.) is: 'Incipit Liber de Chimia In [gold] em et [silver] am'. On fol. 14 is a heading: 'Das Buch ist genandt das Liecht aller Liechter und die Lehr Winandi', and begins: 'Ich Winandus von rothen schild ain arzt...' It seems to end on fol. 15v, line 19: 'Dasz ist dasz Endt des heraufgeschribnen Werkhs', and is followed by extracts on Alchemy including quotations from the 'Turba Philosophorum', as far as fol. 25. Ff. 25v-35 contain 19 symbolic illustrations in the shape of flasks with descriptive text, showing the processes of the Stone. It is headed (fol. 26) 'Rex et Regina desiderant filium generare scilicet creaturam Chimicam....' The illustration is entitled 'Labor primus'. 'Labor secundus' is on fol. 25v: The eleventh flask is omitted. The last (fol. 34v) is of the 'Red Man' or 'Red Elixir'. Following this is a short article in Latin, headed 'Lapis philosophicus', the rest of the title has been obliterated in ink: it seems to deal with 'Murtinlas' [i.e. Salnitrum]. After this (ff. 36, 37) 'Resolutio celebris in [Mercury] Podensteinii' (i.e. Adam von Bodenstein [1528-1577]). This section ends with alchemical notes in German and Latin. The third part is headed: 'Lapidem Philosophorum zu machen nach der Lehr eines Philosophi so vor 200 Jahren gelebt und uns ex speciali gratia communicirt worden'. This appears to end on fol. 9, and is followed by alchemical extracts, notes, and processes. Ff. 23v-28 contain text and pen-drawings relating to alchemical furnaces.
