Ghent Altarpiece
In the images database "BALaT", each artwork is assigned a record number. To reference an artwork page directly, use the code listed at the bottom of the record, usually of the form: http://balat.kikirpa.be/object/ followed by the artwork's record number. For example, the artwork record number for the Ghent Altarpiece is 21, so its BALaT artwork page can be referenced as http://balat.kikirpa.be/object/21.
