The anthropologist John Kennedy, who wrote an early study (The Flower of Paradise) on the use of qāt in Yemen, also took a number of videos in Ṣanā’ in 1975. Several of these are now online on Youtube. Most deal with making the qamariyya windows, but there is also one on architecture, another on Bab al-Sabāḥ and another on a walk through the old suq. The quality of the filming and its reproduction online is poor, but it is well worth watching. The soundtrack is also a useful guide to the actual sounds and dialogue.
