Heimdallr, son of the nine daughters of Aegir and Ran, didn’t sleep because he was the watchman of The Bifrost or The Rainbow Bridge. This was the connection between Asgard, home of the Norse gods, and the outside world. In case of emergency he warned the gods by blowing a horn named Giallarhorn.
Heimdallr, filho das nove filhas de Aegir e Ran, não dormia por ser vigilante da Bifrost ou ponte do arco-íris. Esta fazia a ligação de Asgard, morada dos deuses nórdicos, com o mundo exterior. Em caso de emergência avisava os deuses soprando um corno denominado Giallarhorn.
