The content is the standard Anglo-Saxon genealogies as found in the ASC. With an interesting first page getting us from Adam to Woden. What is most interesting is not the genealogies per se but the scribe's layout of the names on the page, connected by careful and vibrant red lines. There was no attempt to place names inside roundels or employ any other more abstract chart iconography. Rather, here (as also in one of the charts in the near-contemporary Liber floridus of Lambert of Saint-Omer, and one of the Arabic stemmata appearing in Watson's Early Iconography of the Tree of Jesse), the scribe relies on the power of the names themselves to anchor a diagram on the page, with lines simply taking the place of any syntax needed to describe the filiation.
