Chartres Cathedral-North transept facade
In northern Europe it is common for the iconography on the north side of a church to focus on Old Testament themes, with stories from the lives of the saints and the Gospels being more prominent on the physically (and hence, spiritually) brighter southern side. Chartres is no exception to this general principle and the north transept portals, with their deep sheltering porches, concentrate on the precursors of Christ, leading up to the moment of His incarnation, with a particular emphasis on the Virgin Mary. The overall iconographical themes are clearly laid-out; the glorification of Mary in the centre, the incarnation of her son on the left and Old Testament prefigurations and prophecies on the right. One major exception to this scheme is the presence of large statues of St Modesta (a local martyr) and St Potentian on the north west corner of the porch, close to a small doorway where pilgrims visiting the crypt (where their relics were stored) would once have emerged blinking into the light.
