The Cathedral is evocative in the gloom, but it takes a burst of sunshine, as this afternoon, to draw out its full beauty. This photograph, taken in the north transept, shows clearly the line between the finished marble decoration, and the bare brick awaiting its mosaics. The green marble (verde antico) comes from the same quarries that supplies marble for Haghia Sophia and Ravenna. The double 'red stripe' decoration is a copy of that in the great church in Istanbul. Visible on the pier, to the right of the picture, is the bronze of St Theresa by Giacomo Manzu' - a rare departure from our mosaic scheme, but a masterwork by this artist who was the favourite of Pope John XXIII. This is the only work by Manzu' outside Italy.
