The sidelock of youth (also called a Horus lock, Prince's lock, Princess' lock, lock of childhood or side braid) was an identifying characteristic of the child in Ancient Egypt. It symbolically indicates that the wearer is a legitimate heir of Osiris. The sidelock was used as a divine attribute from at least as early as the Old Kingdom.
In earlier depictions, the sidelock can be seen with short hat-like hairstyles in, for example, mortuary cults. Later it was usually attached to an almost shoulder-length wig, which was worn in three styles: curled, straight, or in tresses. Based on the connection between sidelocks and children, Egyptologists coined the term "sidelock of youth". They were worn by both mortal and divine children.[1]
