Religious functions
Cathedrals always have a font or water basin at which the rite of baptism is performed, in which a person is formally accepted into the Christian church. The font is often placed towards the door because the Baptism signifies entry into the community of the church. In some cathedrals, most particularly in Italy, the rite of baptism is performed in a separate building. One of the functions of the cathedral is the reading and expounding upon the Holy Scripture. The cathedral generally has a lectern from which the scripture is read. This often takes the form of an eagle of brass or carved wood which supports the book on its outstretched wings and is the symbol of John the Evangelist. However, some cathedrals retain elaborate medieval structures on either side of the church, one for the reading of the Gospel and the other for the reading of the Epistle.
