A postcard depicting the Ayasofya Mosque with a fascinating inset picture showing the Turkish crescent shoe stamping on the Christian cross and on the reverse of the card the caption reads: 'The Church of the Holy Wisdom' (Saint Sophia) at Constantinople was founded by Constantine the Great in AD 326. The present building was completed by Justinian in AD 537 - seized by the Turks in AD 1453. There can be no peace in Europe till it is restored to Christian worship'.
