This re-evaluation of the Thetford hoard proposes a new date for its burial in the 5th c. CE (ca. 420s–40s), significantly later than the established date of the 380s–90s. The redating is based on comparative material from context-dated grave and hoard finds from across the western Roman Empire. At least 17 hoard artifacts are argued to have been made within the 5th c. The Thetford treasure is a key point of reference in dating artifacts, and therefore a new date, if accepted, will prompt further re-evaluation of material and significantly change our understanding of this key transition period.
The interpretation of the hoard is also revisited. The wide cultural connections that can be demonstrated in the jewelry reflect its assembly in a period of migration and displacement, and there is evidence that its economic value may have become paramount in the latest phase of the assemblage's use. Moreover, the revised date sets a new context for the hoard burial, after economic collapse and political breakdown in Britain. The article advocates for the potential role of wealthy religious sites like Thetford in filling the vacuum left by the collapse of Roman state authority in Britain.
