Sæmundr Sigfússon, The Elder Edda of Saemund Sigfusson and the Younger Edda of Snorre Sturleson… (1907)
“ Odin, especially, was more sensible than the others of the loss they had suffered, for he foresaw what a detriment Baldur's death would be to the Æsir. When the gods came to themselves, Frigga asked who among them wished to gain all her love and good will; 'For this,' said she, 'shall he have who will ride to Hel and try to find Baldur, and offer Hela a ransom if she will let him return to Asgard;' whereupon Hermod, surnamed the Nimble, the son of Odin, offered to undertake the journey. Odin's horse Sleipnir was then led forth, on which Hermod mounted, and galloped away on his mission. ”
