English: The coat of arms of Duchy of Saxony, Angria and Westphalia (Lauenburg) as used between 1507 and 1671. It shows in the upper left quarter the Ascanian barry of ten, in or and sable, covered by a crancelin of rhombs (they are not shown in this undetailed copy) bendwise in vert.^[1] The crancelin symbolises the Saxon ducal crown. The second quarter shows in azure an eagle crowned in or, representing the imperial Pfalzgraviate of Saxony. The third quarter displays in argent three water-lily leaves in gules, standing for the County of Brehna. The lower right fourth quarter repeats the first quarter. The Lauenburg branch duchy adopted this coat-of-arms, altering the one used before by replacing its fourth quarter by reduplicating the first. Before the fourth quarter showed in sable and argent the electoral swords (Kurschwerter) in gules, indicating the Saxon office as Imperial Arch-Marshal (German:Erzmarschall, Latin:Archimarescallus), pertaining to the Saxon privilege as prince-elector, besides the right to elect a new emperor after the decease of the former. The electoral privilege was lost to Saxe-Wittenberg in 1356, but always claimed by Saxe-Lauenburg and reinforced at Saxe-Wittenberg's extinction, however, in vain. But until 1507, when Duke Magnus I ascended the throne, the claim was also upheld by showing the electoral swords in the coat-of-arms. The different quarters of the coat of arms, from then on representing the Duchy of Saxony, Angria and Westphalia (Lauenburg), were later often misinterpreted as symbolising Angria (Brehna's water-lily leaves) and Westphalia (the comital palatine Saxon eagle).
