 When "Codex Regius" was discovered, it seemed that the speculation had proved correct, but modern scholarly research has shown that the "Edda" was likely written first and that the two were, at most, connected by a common source.Brynjólfur attributed the manuscript to Sæmundr the Learned, a larger-than-life 12th century Icelandic priest.Modern scholars reject that attribution, but the name Sæmundar Edda is still sometimes associated with both the "Codex Regius" and versions of "Poetic Edda" using it as a source.
