Heimdall, the son of Odin and nine sister giantesses, is known as the warden of the gods. He is often depicted on horseback at the edge of heaven with his sword and trumpet in hand, guarding the rainbow bridge that connects the human world with Asgard.
In order to help Heimdall in his watch, the gods heightened his senses so that he can hear the grass grow on a hillside and see a 100 league distance in both day and night.
