Thesidelock of youth (also called aHorus lock, Prince's lock,Princess' lock,lock of childhood orside braid) was an identifying characteristic of thechild inAncient Egypt. It symbolically indicates that the wearer is a legitimate heir ofOsiris. The sidelock was used as a divine attribute from at least as early as theOld 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]

The name "sidelock of youth" is not entirely accurate, since it is usually abraid rather than a lock, with its end twisted into a spiral. InMiddle Kingdom depictions, the end is rolled to the front.[2]
The sidelock was generally worn on the right. Inreliefs it can be depicted on the left or the right, since otherwise the lock would not be visible on a figure in profile facing left. A strand of hair was separated off from the side of the skull, itself further separated into three individual braids. The braided portion was held in place by a clasp at its point of origin.
Thereafter there were several different possibilities, such as the triple braided sidelock, whose three strands converged in a spiral. Only in a few cases was it gathered with a clasp at its point of origin and ended with a spiral but left as a loose lock of hair in between.
Further types of divine sidelock are also known. TheHorus lock, like the sidelock, was braided from three strands of hair, which seem to terminate in a claw-like shape and are connected with the goddessMafdet inEgyptian mythology.

The sidelock of youth was used by the children of the pharaohs, not only to show them to be children, but also to indicate their connection to the youthfulHorus. Like them, the young Horus had worn the sidelock as the heir apparent of his fatherOsiris.
In accordance with the mythological precedent, the children of the king, as his designated heirs, received the Horus lock as an indication of the special duties that were bound up with that status. In iconography, royal children were depicted naked and sucking on their finger, with their heads shaved entirely bald except for the sidelock.
Amenhotep I, as well asThutmoses III, reused the special form of the Middle Kingdom, which is connected with their revival of the imagery of the Middle Kingdom more generally. Again in theLate Period, the Middle Kingdom depiction of the sidelock was revived.
With the beginning of theNew Kingdom, the lock of youth achieved central significance as a special symbol of the princes and princesses of the18th Dynasty. Particularly notable is the connection of the lock of youth with princesses, who as children of the reigning king were also seen as probable heirs and therefore were also depicted with the Horus lock.
