The manuscript is something of an enigma as it is not dated and its place of origin is not recorded, there is no trace of who the owners were and no contemporary documents mention it. However close examination of its physical characteristics (size, binding, quality of parchment) and contents (layout, style of writing, illumination) suggest it closely resembles a number of manuscripts made in southern Italy around Palermo and Naples, and illustrated by the artist Jacobellus of Salerno.
