A poliorceticon (Greek: πολιορκητικόν, also transliterated poliorketikon, poliorketika in the plural) is any member of the genre of Byzantine literature dealing with manuals on siege warfare, which is formally known as poliorcetics. As with much Byzantine literature, the poliorcetica tend to be compendia of earlier guides illustrated with Biblical and Classical anecdotes. The extent to which they might be up-to-date or representative of actual experiences in the field is sometimes questionable and greatly depends upon the author.
