Reexamines the evidence--paleographical, art historical, and circumstantial--that Carl Nordenfalk (1907-92) adduced for his hypothesis that Los Angeles, J. Paul Getty Museum, MS Ludwig V 1 (the ten surviving leaves of a sacramentary written and illuminated around the year 1000) was created for the occasion of the consecration in 1017 of Robert the Pious’s ten-year-old son Hugh as his co-ruler. In putting forward this hypothesis, Nordenfalk was building on a suggestion he made first in 1950 that the manuscript was written and illuminated at the behest of Robert the Pious by a Lombard artist named Nivardus, who was working at the royal abbey at Fleury. Nordenfalk's understanding of the fragmentary manuscript as destined for the coronation and the work of a Lombard scribe/illuminator active in the Loire valley has been repeated again and again in the art historical literature of the past half century. This paper reexamines the evidence--paleographical, art historical, and circumstantial--that Nordenfalk adduced for his hypothesis. Paying particular attention to the sacramentary's text and relying in part on a cache of handwritten material dating from the seventeenth to the nineteenth century and preserved at the Mediathèque municipale in Beauvais, I establish that the manuscript was almost certainly made at the behest of Bishop Roger of Beauvais (d. 1016), most probably from a Beauvais exemplar and therefore at Beauvais, as one of three luxury liturgical books he donated to his cathedral.
