 Later in "Skáldskaparmál" poetic terms for the earth are provided, including "Ymir's flesh", followed by a section for poetic terms for "sea", which provides a portion of a work by the skald Ormr Barreyjarskald where the sea is referred to as "Ymir's blood".Both the names "Aurgelmir" and "Ymir" appear in a list of jötnar in the Nafnaþulur section of "Skáldskaparmál".As "Gylfaginning" presents a cohesive narrative that both quotes stanzas from various poems found in the "Poetic Edda" (as outlined above) as well as contains unique information without a provided source (such as Auðumbla), scholars have debated to what extent Snorri had access to outside sources that no longer survive and to what extent he synthesized a narrative from the material he had access to.
