The Vaulting Bosses
Beautiful vaulting bosses - the "buttons" where the lines of the vault meet - can be found in the cross vaulting of the choir aisle and in the wooden vaulting of the choir and the nave.
The vaulting bosses in the choir aisle date from around 1412 and are made of stone. Starting north of the choir screen, the following appear successively: hammer, rosette, angel with portative organ, man with banderol "mint god bovenal" (adore God above all), ox (symbolic for the evangelist Luke), eagle (symbol for the evangelist John), Christ (in the middle behind the choir), angel (symbol for the evangelist Matthew), lion (symbol for the evangelist Mark), followed by four prophets.
The wooden vaulting bosses of the choir and the nave date from around 1420 and from between 1450 and 1520 respectively. From east to west (from choir to nave), they portray the following: Saint Veronica with the sudarium (see illustration), angel (Matthew), lion (Mark), ox (Luke), eagle (John), two vaulting bosses without decorations, blindfolded male head, sun, Leiden coat of arms, Saint Peter, Saint Paul. The last two were installed in the western part that was built after 1512.
