[30] Extremo vitae tempore, cum iam et morbo et senectute premeretur, evocatum ad se Hludowicum filium, Aquitaniae regem, qui solus filiorum Hildigardae supererat, congregatis sollemniter de toto regno Francorum primoribus, cunctorum consilio consortem sibi totius regni et imperialis nominis heredem constituit, inpositoque capiti eius diademate imperatorem et augustum iussit appellari. Susceptum est hoc eius consilium ab omnibus qui aderant magno cum favore; nam divinitus ei propter regni utilitatem videbatur inspiratum. Auxitque maiestatem eius hoc factum et exteris nationibus nun minimum terroris incussit. Dimisso deinde in Aquitaniam filio, ipse more solito, quamvis senectute confectus, non longe a regia Aquensi venatum proficiscitur, exactoque in huiuscemodi negotio quod reliquum erat autumni, circa Kalendas Novembris Aquasgrani revertitur.

Cumque ibi hiemaret, mense Ianuario febre valida correptus decubuit. Qui statim, ut in febribus solebat, cibi sibi abstinentiam indixit, arbitratus hac continentia morbum posse depelli vel certe mitigari. Sed accedente ad febrem lateris dolore, quem Greci pleuresin dicunt, illoque adhuc inediam retinente neque corpus aliter quam rarissimo potu sustentante, septimo, postquam decubuit, die, sacra communione percepta, decessit, anno aetatis suae septuagesimo secundo et ex quo regnare coeperat quadragesimo septimo, V. Kalendas Februarii, hora diei tertia.

Coronation of Louis - Charlemagne's Death

[30] Toward the close of his life [813], when he was broken by ill-health and old age, he summoned Louis, Kigi of Aquitania, his onlv surviving son by Hildegard, and gathered together all the chief men of the whole kingdom of the Franks in a solemn assembly. He appointed Louis, with their unanimous consent, to rule with himself over the whole kingdom and constituted him heir to the imperial name; then, placing the diadem upon his son's head, he bade him be proclaimed Emperor and is step was hailed by all present favor, for it really seemed as if God had prompted him to it for the kingdom's good; it increased the King's dignity, and struck no little terror into foreign nations. After sending his son son back to Aquitania, although weak from age he set out to hunt, as usual, near his palace at Aix-la-Chapelle, and passed the rest of the autumn in the chase, returning thither about the first of November [813]. While wintering there, he was seized, in the month of January, with a high fever Jan 22 814], and took to his bed. As soon as he was taken sick, he prescribed for himself abstinence from food, as he always used to do in case of fever, thinking that the disease could be driven off , or at least mitigated, by fasting. Besides the fever, he suffered from a pain in the side, which the Greeks call pleurisy; but he still persisted in fasting, and in keeping up his strength only by draughts taken at very long intervals. He died January twenty-eighth, the seventh day from the time that he took to his bed, at nine o'clock in the morning, after partaking of the holy communion, in the seventy-second year of his age and the forty-seventh of his reign [Jan 28, 814].
