The Brother Ambrose was ever a saintly man approved of God and beloved by the Brethren. To him one night, as he lay abed in the dormitory, came the word of the Lord, saying, "Come, and I will show thee the Bride, the Lamb's wife." And Brother Ambrose arose and was carried to a great and high mountain, even as in the Vision of Blessed John. 'Twas a still night of many stars, and Brother Ambrose, looking up, saw a radiant path in the heavens; and lo! the stars gathered themselves together on either side until they stood as walls of light, and the four winds lapped him about as in a mantle and bore him towards the wondrous gleaming roadway. Then between the stars came the Holy City with roof and pinnacle aflame, and walls aglow with such colours as no earthly limner dreams of, and much gold. Brother Ambrose beheld the Gates of Pearl, and by every gate an angel with wings of snow and fire, and a face no man dare look on because of its exceeding radiance. Then as Brother Ambrose stretched out his arms because of his great longing, a little grey cloud came out of the north and hung between the walls of light, so that he no longer beheld the Vision, but only heard a sound as of a great multitude crying 'Alleluia'; and suddenly the winds came about him again, and lo! he found himself in his bed in the dormitory, and it was midnight, for the bell was ringing to Matins; and he rose and went down with the rest. But when the Brethren left the choir Brother Ambrose stayed fast in his place, hearing and seeing nothing because of the Vision of God; and at Lauds they found him and told the Prior. He questioned Brother Ambrose of the matter, and when he heard the Vision bade him limn the Holy City even as he had seen it; and the Precentor gave him uterine vellum and much fine gold and what colours he asked for the work. Then Brother Ambrose limned a wondrous fair city of gold with turrets and spires; and he inlaid blue for the sapphire, and green for the emerald, and vermilion where the city seemed aflame with the glory of God; but the angels he could not limn, nor could he set the rest of the colours as he saw them, nor the wall of stars on either hand; and Brother Ambrose fell sick because of the exceeding great longing he had to limn the Holy City, and was very sad; but the Prior bade him thank God, and remember the infirmity of the flesh, which, like the little grey cloud, veiled Jerusalem to his sight.
