We have numbered the extant pieces of wax from left to right, taking the top left of the document as a theoretical starting point and working around the edge of the document. Where two or more pieces of wax are found on one attachment, we have counted out or down from the end of the attachment closest to the document.
While some documents were dated, this only became commonplace towards the end of the 13th century. The date range presented in this database represents the time span within which the document was probably composed based on identifiable individuals, events or relationships to other documents.
