Medard, and Einhard's transport of the relics of SS. Marcellinus and Peter into Francia. A more detailed account of Einhard's procurement of the relics exists in his Translation and Miracles of Marcellinus and Peter. Additionally, the annals provide the only attestation to the existence of Charlemagne's personal elephant Abul-Abbas, aside from a mention by Einhard drawn from the annals. The gift of the elephant to Charlemagne, amongst other treasures, by Abbasid Caliph Harun al-Rashid is evidence of the attempts to form an Abbasid-Carolingian alliance at the time, which the annals document loosely. Classification The annals survive in multiple versions, widely distributed across the Frankish empire, though none of these are original copies. Each version is marked with distinguishing features, and based on these features, Friedrich Kurze formulated five classes for the categorization of these texts. This system still remains in use. The five classes of texts are lettered A through D, with an additional E class for the revised text. They are as follow: Class A Class A texts end at the year 788, and are reflected in one of the earliest modern printings of the annals, that of Heinrich Canisius's Francicorum Annalium fragmentum. Canisius also includes the years up to 793 in his printing, however, and Rosamond McKitterick speculates that the manuscript originally ran to that date. These manuscripts are now lost. Class B Class B texts go to, at the latest, 813. Kurze notes that one of these was used by Regino of Prüm in his Chronicon. Class C Class C texts are complete through 829. These contain various additions not found in the previous two classes, and Kurze divides them based on what other texts are found in their codices, such as the Liber historiae Francorum. Class D Class D texts are derived from a complete copy, though McKitterick points out that the derivatives are often not complete themselves. These also contain insertions not found in the other classes, including mention of Pepin the Hunchback. The revised texts are based on a Class D manuscript. Class E Class E comprises the revised editions of the annals, and are by far the most numerous. These are often found paired with Einhard's Vita Karoli Magni, and it is partially from this that they are sometimes believed to have been written by him as well, and thus called the Annales qui dicuntur Einhardi (English: Annals which are said to be
