Provenance: 'a continental hand'/'scribe' (Stokes & Strachan, 1987, II, p. xvii). Specifically, 'the manuscript was brought from France', 'according to Hagen' (p. xvii). The glosses are early. Sometimes they are associated with Adamnán's school in Iona, although the link is not certain. We follow the judgment of Stokes and Strachan who say that the language of the glosses is the comparable to the language of the Book of Armagh. I understand them to mean specifically the Patrician section. 690 is chosen here as a date towards the end of the 7th century, similar enough to Muirchú's dates in the Book of Armagh. (Muirchú was writing for his Bishop Áed of Sletty). 740 is the latest date that could be associated with the Additamenta in the book of Armagh. The weight is assigned on the basis of Adamnán's death, on the assumption that Adamnán was the teacher mentioned by the scribe in the note. See VAQ and attached document 'Old Irish Glosses - Dating'.
