The name Edda is given to two interrelated bodies of mythology originating in Iceland in the thirteenth century. Snorra Edda (otherwise called the “younger” or “prose” Edda) is attributed to the Icelandic chieftain Snorri Sturluson and was probably composed around 1220. The Poetic Edda (or “elder” Edda) is a manuscript from about 1270 that collects a number of anonymous poems about the Norse gods and legendary heroes. Many of these poems are likely to be much older than the manuscript itself, and some may date back to the period before the conversion of Iceland to Christianity around 1000. Snorra Edda also quotes from several of the poems that are preserved in the Poetic Edda, proving that these texts were in circulation in Iceland before the Poetic Edda manuscript was produced.
