Kerlaugar

In Norse mythology, the Kerlaugar (plural form of Old Norse kerlaug "kettle-bath",^[1]) i.e. "bath-tub", are two rivers through which the god Thor wades. The Kerlaugar are attested in the Poetic Edda, compiled in the 13th century from earlier traditional material, and in a citation of the same verse in the Prose Edda, written in the 13th century by Snorri Sturluson.
