Night cap
A night cap , also called a sleeping cap , is a soft head covering that was worn in bed because bedrooms weren't as well heated as they are today, if at all. While the shape of the sleeping cap for men corresponded to a pointed cap , women wore a sleeping cap with folds of fabric.
In the 19th century, night caps were often used in surgery to hold bandages in place on the head. The pictography shows a moon with a sleeping cap as a symbol of sleep.
In a figurative sense, since the 18th century, the term “sleepyhead” also means a slow, clumsy, inattentive or lazy person or a late riser. In the political cartoon , the sleeping cap is an attribute of the German Michel .
