Fragmentary source consisting of a section of parchment taken from a rotulus and attached as a pastedown (now, as a flyleaf) to the cover of a fifteenth-century book from the Cistercian nunnery of Lichtenthal that contains a collection of diverse texts in German. The musical fragment contains the end of the second voice of the Fa fa mi fa motet known from the Codex Las Huelgas, the upper part of Flos vernalis, known from the Robertsbridge Codex, and polyphonic settings of Virgo Dei genitrix and Ave sidus lux dierum.

Inventoried by Felix Heinzer and Gerhard Stamm, 1987. Concordances discovered by Cristina Alís Raurich, January 2011.

Note that the attached edge of the musical flyleaf is visible between folios 164v and 165r, and contains the visible initial F for Flos vernalis which begins halfway down on the verso side. The backboard also contains an offset of the verso side of the leaf.
