“The present life of man, O king, seems to me, in comparison of that time which is unknown to us, like to the swift flight of a sparrow through the room wherein you sit at supper in winter, with your commanders and ministers, and a good fire in the midst, whilst the storms of rain and snow prevail abroad; the sparrow, I say, flying in at one door, and immediately out at another, whilst he is within, is safe from the wintry storm; but after a short space of fair weather, he immediately vanishes out of your sight, into the dark winter from which he had emerged. So this life of man appears for a short space, but of what went before, or what is to follow, we are utterly ignorant. If, therefore, this new doctrine contains something more certain, it seems justly to deserve to be followed.”

Book II, chapter 13
This, Bede tells us, was the advice given to Edwin, King of Northumbria by one of his chief men, at a meeting where the king proposed that he and his followers should convert to Christianity. It followed a speech by the chief priest Coifi, who also spoke in favor of conversion.
