This treaty about plants was likely originally not illustrated. The earliest illustrated copy is BL Egerton 747 (1300). The text of BNF Lat 6823, 1300-1350, Naples?, Manfredus de Monte Imperiali is an expanded version of the “Circa Instans”; this ms contains the oak and ivy picture that Ellie, Rene and others paralleled with VMS f35v. Both manuscripts contain several other texts, among which both include a copy of Antidotarium Nicolai (see below).
These two manuscripts are strictly: the illustrations do not contain the zoomorphic and anthropomorphic elements that appear in the VMS and Italian popular herbals dating to 1400 ca. But the “Tractatus de Herbis” also merged with that popular tradition, e.g. in the several ms that contain both the “alchemical herbal” and plants from the Tractatus de Herbis (e.g. BNF Lat 17844 and 17848).
