The term "agger perpendicularis" is a Latin word used to describe a perpendicular mound or wall. Its spelling can be explained using the International Phonetic Alphabet (IPA) as follows: /ˈæɡər pəˌpɛndɪkjʊˈlaɪs/. The first part of the word "agger" is pronounced as "ag-ger" with a short "a" sound and a "g" sound. The second part "perpendicularis" is pronounced as "per-pen-dic-yu-lis" with a stress on the "pen". Overall, its spelling and pronunciation can be quite challenging for non-Latin speakers.
Agger perpendicularis is a Latin term used in the field of Archaeology and Ancient Roman history to describe a particular type of defensive earthwork or fortification. Literally translated, it means "perpendicular rampart" or "vertical embankment."
An agger perpendicularis refers to a defensive rampart that was constructed at a right angle or perpendicular to the main walls of a fortification or a Roman military camp. It was typically built using a combination of soil, gravel, stones, and other available materials. The purpose of this feature was to strengthen the fortification's defenses and provide an additional layer of protection, particularly against lateral attacks or attempts to breach the walls.
This type of rampart was often constructed together with the main walls and was designed to create an elevated platform or raised mound. The agger perpendicularis would be situated slightly away from the main walls, running parallel to them, and formed a sort of buffer zone. It would act as an obstacle to hinder enemy advancement and force attackers to navigate through difficult terrain.
Archaeological evidence suggests that agger perpendicularis was commonly used in Roman military architecture during the late Republic and the Imperial period. The construction and positioning of these ramparts varied based on the particular strategic needs of each fortification or military camp.
In summary, agger perpendicularis refers to a perpendicular rampart or embankment built alongside the main walls of a fortification or Roman military camp. It served as an additional defensive measure aimed at deterring and hindering lateral attacks.
