The latest wife of the king, Luitgard, has eight pretty lines devoted to her, after an inauspicious opening address to “the fair virago, Luitgard”. This dates the poem before 801, in which year Luitgard died at Tours. The tower of St. Martin’s, now called the tower of Charlemagne, was raised over her tomb.[225] Alcuin was evidently a very prominent figure at court, keeping things alive by his knowledge and wit and subtleties. And Flaccus too is there, the glory of our poets, Who pours forth many things in lyric foot. An able sophist, a poet, too, melodious, Able in mind and able in practice alike. He brings forth pious lessons from Holy Writ, And solves the puzzles of numbers with favouring jest. He puts an easy question now, and then a hard; Of this world now, then of the world above. The king alone, of many that fain would, Can solve the skilful puzzles Flaccus sets. There was evidently no standing ill-feeling against the Abbat of St. Martin’s on the part of the Bishop of Orleans. CHAPTER XV Alcuin’s letters to Charlemagne’s sons.—Recension of the Bible.—The “Alcuin Bible” at the British Museum.—Other supposed “Alcuin Bibles”.—Anglo-Saxon Forms of Coronation used at the coronations of French kings. There is in the Bibliothèque Nationale in Paris a letter headed “In nomine Dei summi incipit scriptum Albini magistri ad Karolum imperatorem”. It is, however, held to be uncertain whether the letter is addressed to the emperor or to his son Charles, who died some three years before his father. The internal evidence appears to be decidedly against its having been addressed to the emperor. Alcuin could not have denied himself the pleasure of referring to the emperor when he mentions king David as the authority for his advice, and we have no letter of Alcuin to the emperor so completely free from honorific titles and phrases, with nothing but the simple _vos_ throughout. It is to be said on the other hand that the author of the _Life of the blessed Alchuin the Abbat_, with which we dealt fully in Chapters I and II, refers[226] to a _libellus_ which Alcuin wrote for Charlemagne, setting forth the psalms which he was to use according as penitence, tribulation, or joy, was his theme. The interest of the letter in question fortunately lies in its advice, not in the person to whom the advice is given. This is the letter, with its ordinary heading:— [Sidenote: Ep. 244.] “Alcuin dedicates to Charles the Emperor a breviary[227] of prayer to God.
