 In addition, all the ornamentation of yeserias of the palace was polychrome in shades of blue and red in the back and gold in the arabesques.Among the filigrees is the representation of a bird, an unusual zoomorphic figure in Islamic art that could represent a pigeon, a pheasant or a symbol of the king as winged.The traces of interlocking mixtilinear arches are characteristic of this palace and are given for the first time in the Aljafería, from where they will be diffused to the future Islamic constructions.
