The watchman of the gods. Heimdall is the guardian of Bifrost and he possesses the horn Giallar. His horse is Gulltop and his sword is Hofund. He is a great watchman as his eyesight is so sharp that he can see for 100 miles in all directions as plainly by night as by day, his hearing is such that he can hear the grass pushing up from under the earth and the wool growing on a sheep's back and he requires less sleep than a bird. He is also purported to have "second sight" that allows him to see into the future. Heimdall is also a clever god. It was his idea to send Thor to Jotunheim to retrieve Mjollnir from the giant Thrym. (See The Theft of Thor's Hammer for the story). Heimdall was also known as Rig during his journey to Midgard
