In this manner the Báb spent the summer and autumn within the walls of that castle. A winter followed of such exceptional severity that even the copper implements were affected by the intensity of the cold. The beginning of that season coincided with the month of Muharram of the year 1264 A.H. [December 9, 1847-January 8, 1848 A.D] The water which the Báb used for His ablutions was of such icy coldness that its drops glistened as they froze upon His face.
