<P> The lateral portals are dedicated to the Jews on the left and to the unbelievers on the right . </P> <P> The right tympanum is divided into three parts and is dedicated to the theme of salvation . In the centre are Christ and St Michael, flanked by Hell (represented by demons) and Heaven (represented by children). Purgatory is shown on the side . The left tympanum shows scenes from the Old Testament . </P> <P> Demons are represented at the bottom of the pórtico, signifying that Glory crushes sin . </P> <P> Behind the portico stands the statue of Maestro Mateo, the master architect and sculptor put in charge of the cathedral building programme in the 12th century by Fernando II . It is said that whoever butts their head three times against the statue will be given a portion of Mateo's genius and perhaps enhanced memory . There was foemerly a long line of visitors waiting to bump their head against the statue, but he is now blocked off because a hole has started to indent into him from all the head bumps . </P>
