Then Gangleri said, ‘What is the path from the earth to the sky?’
Then, snickering, High answered: ‘Your question shows little knowledge. Haven’t you heard that the gods built a bridge from the earth to the sky and it is called Bifrost? You will have seen it, and possibly you call it the rainbow. It has three colours and great strength, and it is made with more skill and knowledge than other constructions. Sturdy though it is, it will break when the sons of Muspell ride over it [at Ragnarok]. Then their horses will swim across great rivers and so they will advance.’
Then Gangleri said, ‘Since they can do whatever they wish, it seems to me that the gods did not build the bridge reliably if it will break.’
High replied, ‘The gods deserve no blame for the construction. Bifrost is a sound bridge, but nothing in this world can be trusted when the sons of Muspell attack.’
