This is a genealogical chart depicting a royal lineage, presumably of Scottish origin. The chart displays a detailed family tree with names in circles connected by lines. At the top center, there is a circular portrait labeled as "Achaius Scotorum Rex," surrounded by heraldic symbols. Another crest is shown on the right supported by a lion and unicorn. The names on the chart are topped with small crowns and accompanied by Latin text. The overall presentation is typical of genealogical manuscripts from that period.
