In Norse mythology, #Sinmara is a gýgr (giantess), usually considered a consort to the fiery jötunn Surtr, the lord of Muspelheim, but wife of #Mimir. Sinmara is attested solely in the poem Fjölsvinnsmál, where she is mentioned alongside Surtr in one (emended) stanza, and described as keeper of the legendary weapon Lævateinn in a later passage. Assorted theories have been proposed about the etymology of her name, and her connection with other figures in Norse mythology. #godofwarragnarokshorts
