Capeline

Lobster-tailed pot helmet, also known as the zischägge, horseman's pot and harquebusier's pot, was a type of combat helmet. It was derived from an Ottoman Turkish helmet type. From c. 1600, it became popular in most of Europe and was especially worn by cavalrymen and officers. The helmet gradually fell out of use in most of Europe in the late 17th century; however, the Austrian heavy cavalry retained it for some campaigns as late as the 1780s.
