The development of the Isidoran collection is reexamined through a close analysis of a charter recording the 1063 donation together with early thirteenth-century writings by Lucas of Tuy. Documentary evidence is further weighed against visual analysis and technical studies of several key pieces From the medieval collection. In particular, the Beatitudes Casket (now at the Museo Arqueológico Nacional, Madrid) is singled out to demonstrate how art historical, epigraphic, and historical re-search come together with carbon-14 testing, revealing that this object was assembled in a very different moment from those traditionally assumed.
