from the Battle of Tertry onwards." This change in focus, while not invalid per se, certainly is problematic, because the Annales were written long after the time period they describe. This is especially important, notes Wood, because "as a reading of history the so-called Metz Prior Annals have been extremely influential, providing the most popular interpretation of the late Merovingian period. Nevertheless, they show the Pippinids and Merovingian history as the Carolingians wished to see them." Despite this different focus, even the Metz Annales do not state that Arnulf is Ansegisel's father, saying only that he is a great ally of Pippin. Wood believes that the shift in focus of the Metz Prior Annals is deliberate, citing the need to glorify the sanctity of the newly powerful Pippinids. "The other asset which the family was to develop, its sanctity, was beginning to be realized only in the last decades of the seventh century. Although Arnulf of Metz is thought to have been Pepin II's grandfather, the evidence for this is not early, and even the Annales Mettenses Priores were uncertain about the nature of the relationship between Arnulf and the Pippinids." According to Wood, this link comes first from Paul the Deacon (Gesta episcoporum Mettensium) and is suspect, as Paul was not familiar with the events he was writing about and had limited access to reference materials. Of the other early sources that might establish a link between Ansegisel and Arnulf, all that is left is the Vita Arnulfi, or "Life of Arnulf." However, according to Wood, it is "not clear that the Vita Arnulfi... was written in the seventh century." It is possible that this work was a forgery, created later to sanctify the Carolingian line. This argument is not without base, because after Gertrude died in 659, "her sanctity was unquestionably promoted by the family in the late seventh century" beginning with her 'Vita in 670. Recent popular culture The assignment of Gertrude as patron of cats and the designation of the cat as one of her attributes seems to date from the 1980s. It is not mentioned at all in Madou's extensive historical survey from 1975. A more superficial association of Gertrude with the cat as a mouse hunter goes further back. Her veneration as protector against rats and mice dates from the early 15th century during the Black Plague and spread from Southwestern Germany to the
