Deshret

[2] Other deities wore the deshret too, or were identified with it, such as the protective serpent goddess Wadjet and the creator-goddess of Sais, Neith, who often is shown wearing the Red Crown.

Several ancient representations indicate it was woven like a basket from plant fiber such as grass, straw, flax, palm leaf, or reed.

A label from the reign of Djer records a royal visit to the shrine of the Deshret which may have been located at Buto in the Nile delta.

[5] The fact that no crown has ever been found buried with any of the pharaohs, even in relatively intact tombs, might suggest that it was passed from one reign to the next, much as in present-day monarchies.

The first usage of the Red Crown was in iconography as the symbol for Lower Egypt with the Nile Delta, horizontal letter 'n', Gardiner no.

Visually it is also a hieroglyph that takes up more 'space'-(versus a straight-line type for the horizontal water ripple); so it may have a dual purpose of a less compact text, and a better segue-transition to the next words.

Rosetta Stone usage of Red Crown, not as preposition: part of Pschent (Double Crown), and part of "Taui" , the name for Upper and Lower Egypt (used combined with a Crossroads (hieroglyph) )
