Radiate crown

It comprises a number of narrowing bands going outwards from the wearer's head, to represent the rays of the Sun.

[4] In Ptolemaic Egypt, the solar crown could also be a radiate diadem, modeled after the type worn by Alexander the Great (as identified with the sun god Helios) in art from the mid-2nd century BC onward.

[7] The first ruler of Egypt shown wearing this version of a solar crown was Ptolemy III Euergetes (246–222 BC).

[11] The solar crown worn by Constantine, the first emperor to convert to Christianity, was reinterpreted as representing the "Holy Nails".

The radiate crown became associated with Liberty personified, usually in a form of a circular disc with rays in different directions.
