The choir of Lyons' Cathedral, up to its vault-springing, is Romanesque, of the Burgundian and Provençal type. The classic pilaster strips are channeled; on each arm of the transept is an apsidal chapel. The prelate who began it, Guichard, had, while abbot of Pontigny, been the host of St. Thomas Becket, and in Pontigny's church he was buried in 1180. His successor, Jean de Bellesmaine (1180-93), born in Canterbury, was another of Becket's friends, and soon after he was transferred here from the see of Poitiers, then under English rule, he inspired the building of a collegiate church dedicated to the new English saint. Archbishop John undertook the second campaign of works on Lyons' choir, which was now vaulted in the Gothic way. On the capitals of the upper walls are the familiar crockets of the north.
In the transept is to be seen the same change from the round arches and fluted pilaster strips of the Romanesque day to the Primary Gothic characteristics. During the first third of the XIII century the transept was vaulted, its two towers raised, and the choir's four easternmost bays built. Lyons was then governed by one of its best rulers, Archbishop Renaud de Forez, who laid here the base for several centuries of prosperity. Circumstances forced him into the position of a leader of armies, but his natural inclination led him to the cloister's peace to end his days. In 1226, as president of a free city, he received Louis VIII, shortly before that king's sudden death.
This capable churchman presented to his cathedral the seven magnificent lancets in the curving sanctuary wall, that glow with the sparkling jewel-radiance achieved before 1220, but never equaled afterwards. The windows at Lyons are linked with those at Sens, and Sens' lancets we know to have been related to the earlier school of Chartres. What differentiates Lyons' medallions from those in the north was their use of certain Byzantine arrangements, such as the Virgin reclining on a couch in the Bethlehem grotto, or the representing St. John with a beard.
The first light in the Lyons' chevet celebrates the local martyrs. The axis window is a New Alliance, wherein the Old Law symbolizes the New. The meaning of its animal allegories was first explained by Père Cahier, who observed that they were taken from the ancient book called the _Bestiaires_. M. Mâle further discovered that Lyons' New Alliance window showed only those animals spoken of in Honoré d'Autun's popular _Mirror of the Church_. Honoré, who taught in Autun's cathedral school early in the XII century, was the initiator of animal symbolism in French cathedrals.
