‘Aspilogia’ means materials of heraldry, and this first volume in the series on heraldry published by the Society of Antiquaries is a comprehensive listing of the known medieval rolls of arms of English origin. The rolls vary fromvery grand and luxurious painted manuscripts to simple records made by heralds using descriptive code, and this book is the best guide to them. It includes details of all known copies and variants, and includes rolls which are only known to us through later transcripts.
