Another of the king’s chief men, approving of his wise words and exhortations, added thereafter: ‘The present life of man upon earth, O king, seems to me, in comparison with that time which is unknown to us, like to the swift flight of a sparrow through the house wherein you sit at supper in winter, with your ealdormen and thegns, while the fire blazes in the midst, and the hall is warmed, but the wintry storms of rain or snow are raging abroad. The sparrow, flying in at one door and immediately out at another, whilst he is within, is safe from the wintry tempest; but after a short space of fair weather, he immediately vanishes out of your sight, passing from winter into winter again. So this life of man appears for a little while, but of what is to follow or what went before we know nothing at all. If, therefore, this new doctrine tells us something more certain, it seems justly to deserve to be followed.’
