214 The miniatures of the Vienna Genesis: colour identification and painters’ palettes of read lead and cinnabar (HgS) like for the flames on folio 1, page 2 and on folio 2, page 4. Cinnabar is indicated by peaks of mercury (Hg) on the XRF spectrum (Fig. 10) and by an inflexion point of approx. 600 nm on FORS spectra (Fig. 11). It is difficult to visually differentiate between red lead, cinnabar and red ochres. Painter A might have added cin- nabar to his palette to paint some areas, e. g. the flames, more vividly. He might have used cinnabar more frequently on folios that are now missing. For pink painter A used madder lake mixed with lead white, a common habit of all Fig. 9: Miniature on folio 5, page 10, Lot and his daughters. Fig. 10: XRF spectra of red areas on folio 1, page 2 (MP1_14) and folio 5, page 10 (MP5_4). For comparison a spectrum of blank parchment of folio 5 (MP5_7) shows the background signal detected.
