The source for this podcast presents a typology and chronology of Anglo-Saxon sword pyramids, primarily from England, based on a corpus of 224 examples. The author examines their design variations, distribution, and potential significance, exploring theories regarding their purpose, including casual loss versus deliberate deposition as votive offerings. The study also considers the potential symbolic meaning of recurring design elements like triangles and the number three, and discusses the craftsmanship and materials used in their creation, noting variations in quality. Finally, the paper speculates on the pyramids' possible functions as status symbols or indicators of military affiliation.
