The Prose Edda on Skrymer
The Younger Edda: > Chapter Xiv. > Thor'S Adventures.
attestation: Skrymer was so enormous he did not need to ask Thor's name, already recognizing him as Asa-Thor
"He called himself Skrymer; but, said he, I do not need to ask you what your name is,--I know that you are Asa-Thor."
attribution: Skrymer warned Thor that Utgard-Loke's thanes would not tolerate boasting from small fellows, advising them to turn back
"Do not brag too much of yourselves, for Utgard-Loke's thanes will not brook the boasting of such insignificant little fellows as you are; otherwise turn back, and that is, in fact, the best thing for you to do."
attestation: Skrymer directed Thor toward Utgard, a burg to the east, while he himself headed north toward the mountains
"But if you are bound to continue your journey, then keep straight on eastward; my way lies to the north, to those mountains that you there see."
