As well as being an invaluable source for modern historians studying the Hellenistic period, the book was very influential on military theory long after Aelian's death. Arrian's work on tactics may merely be a revision of Aelian's; the Byzantine Emperor Leo VI used excerpts in his own treatise and an Arabic translation made around 1350 was used to train Muslim armies. Most significantly it became one of the primary training aids for the pike and musket armies of the 16 and 17th century Europe. A substantial edition published in London in 1616 contained a full direct translation as well as comprehensive notes and a treatise on how to apply Aelian's work to the training of English pike formations in the Macedonian manner. It was well used to train the foot regiments that fought the English Civil War. This unique longevity makes it of interest to anyone interested in warfare from the Hellenistic period right up to the English Civil War.
