Tudela - Catedral de Santa Maria

The Catedral de Santa Maria in Tudela was erected late 12th century on the place, where the Great Mosque of Tudela (9th c.) had stood before. The cathedral is really large (65m x 52m) but unfortunately was closed, so I could not see the well known cloister.

I was very impressed by the late-Romanesque "Puerta del Juicio". The slightly pointed portal, created wirthin the 13th century, has eight archivolts and 122 different icons. On the left side is an insight view into hell, demons and devils at work.

Two tall devils torture a small guy with two-pronged forks. The person is holding a rectangular object in his hand, what could be a (damaged) Roman abacus. In case this is right, the scene depicts, what fraudulent mathematicians have to expect.

Here is what Wiki knows about the Roman abacus:
