Einzelbemerkungen: |
Ms.: Wien, Nationalbibl. MS 5239, fol. 19b-23a.
Autorschaft:
- "The work is based in part on the Tractatus de Quadrante of Robertus Anglicus. ... The scribe, perhaps influenced by the presence of genuine works of Grossetest in the codex from which he was copying, or in an earlier part of this same codex, must have hazarded the attribution." [Thomson (1940), 261].
