THE HEIGHT OF EDWARDIAN ENGLISH BOOK ART IN A SPECTACULAR BINDING, this unique manuscript showcases the greatest English calligrapher and miniaturist, celebrating and illuminating the greatest epic poem of the Poet Laureate of the Victorian Age. The title-page contains a large historiated initial "M" enclosing a fine large miniature showing Sir Bedivere holding the head of the dying King Arthur in his arms, within an elaborate floral border in colors and burnished gold framed with crossed swords and surmounted with an Arthurian helmet in silver and gilt; in the lower right is a heraldic shield containing Arthur's coat-of-arms of 13 gold crowns. The facing page opens the text with a large illuminated initial "S" in colors and burnished gold with an elaborate, full decorated border historiated with dragons and fantastic creatures in colors and heightened with burnished gold. The final page of the poem's text is bordered on three sides incorporating an illuminated initial "S" and a large vignette at foot portraying Arthur's funeral barge with the weeping maidens bending over the dead king; the text throughout is decorated with 6 other illuminated initials mostly decorated in colors and burnished gold, some with partial borders, the decoration in bright, bold colors of orange, purple, blue and green, mostly in a Gothic style.

This manuscript dates from the period almost immediately after the illuminator Alberto Sangorski professionally separated from his brother Francis's bookbinding from Sangorski and Sutcliffe, and instead went to work for Riviere (Sangorski and Sutcliffe's chief competitor); indeed, it might very well be Alberto Sangorski's first collaboration with the Riviere firm.
