The lobster-tailed pot helmet, also known as the zischägge, horseman's pot and harquebusier's pot, was a type of post-Renaissance combat helmet. It became popular in Europe, especially for cavalry and officers, from c. 1600; it was derived from an Ottoman Turkish helmet type. 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.
