Two figures sit in quiet repose beneath a horseshoe-arched doorway of the Mosquée des Isawia in Tanger, Morocco — the ornate polychrome minaret rising dramatically above the medina rooftops in a hand-coloured composition that captures the city's layered spiritual life around the turn of the twentieth century. The minaret's zellige tilework panels in turquoise, gold and ochre are rendered with exceptional clarity, while the terracotta-tiled canopy over the entrance gate frames a deep shadow that gives the scene its painterly depth. The Isawiyya brotherhood, a Sufi order founded in Meknès, maintained an important zawiya in Tanger, and this mosque was among the most photographed monuments in the city during the French and Spanish protectorate era. Published by Benzaquen & Co. of Tanger — one of the city's principal postcard houses — on stock numbered D 1830, this unused card is a fine example of the coloured collotype production that catered to European travellers passing through Tanger's busy international port.
