Bellifortis (, 'War Fortifications') is the first fully illustrated manual of military technology, written by Konrad Kyeser and dating from the start of the 15th century. It summarises material from classical writers on military technology, like Vegetius' De Re Militari and Frontinus' anecdotal Strategemata, emphasising poliorcetics, or the art of siege warfare, but treating magic as a supplement to the military arts; it is "saturated with astrology", remarked Lynn White, Jr. in a review of the first facsimile edition.
