The tympana of 11r-15r include the heads of the evangelist symbols (often drastically cropped); while those of 10v, 15v and 16r are purely decorative.
Of the tower's two upper stage belfry openings, one is bounded on its sides by narrow columns and headed by a tympana arch containing trefoils.
Smooth glandular structures (known as the supratympanic fold) extend over the tympana from the eyes to the edges of the lower jaw.
The mantis ear, located in the midline between the metathoracic (third) legs, comprises two tympana within an auditory chamber that enhances sensitivity.
Four additional entrances, two on each side of the building, also have glass mosaics in their tympana.
The lower section of walls is lined with blue-green tiles, also used in tympana of windows on the interior.
Tympana, if present, are on the sides of the first abdominal segment.
The discs on the second, third, and fourth fingers are about the same diameter as the tympana.
