The Saints are depicted in their standard late-medieval forms. St. Peter is seen in his robes as First Bishop of Rome, holding the symbolic keys given to him by Christ.  St. John the Baptist holds the Mystic Lamb of God and is shown barefoot, symbolic of his sojourn in the wilderness.  St. Augustine appears as one of the Four Doctors of the Church, correctly mitred. The Archangel Michael, is shown vanquishing the devil, whilst St. Bartholomew holds the knife with which he was martyred. St. Paul is seen with his sword of Martyrdom and his Epistles.  The whole emphasis is on the richness of the Saint Paul’s apparel, and even the normally austere St. Bartholomew is shown in an elaborately decorated robe.  It is certain that this series of Saints with their gilded tracery work comes from a very much larger complex and probably forms part of the predella. Large scale painted altarpieces were very popular in late medieval Spain. These were often composed of dozens of panels of differing sizes with gilt backgrounds and gothic tracery work.  Some of these survive in situ, especially in Catalonia. A rare example of such a complete altarpiece, outside Spain, is the Altarpiece of St. George attributed to the 15th century Valencian painter, Marczal de Sas (working 1420s) , in the Victoria and Albert Museum, London.
