The Sky hieroglyph can be found in iconography with the gods, especially Ra as referencing the Lord of P(e)t, (Lord of Heaven), and the God's ownership of Pet. The Pharaoh is often equally named as the Lord of Pet.
Some ancient Egyptian names using the sky hieroglyph are Petosiris and the god Petbe.
Though the sky hieroglyph is used as pt, in the Coptic alphabet, for the Coptic language, (the follow-on to the Egyptian hieroglyphs), the spelling of the "sky" is "pe" in Coptic. Consequently, Budge's 2-volume dictionary lists the sky hieroglyph under "pe-t"
In the short P word section in the Egyptian dictionaries, the end of the P's has the pd, and pdj. In the languages the d's and t's are listed together; they are the unaspirated and the aspirated. (See d, and dj, the hieroglyphs for "hand" and "cobra".) The pd is represented by 'feet', and parts of them, and 'running', and the hieroglyph for 'extend', Gardiner no. T9-(similar to a bow),
(Many of the entries also refer to items about the bow, i.e. "stringing a bow", etc.) The pdj then refers to bowmen, etc., and especially the Nine bows. The archers of the 1350 BC Amarna letters, the archers (Egyptian pitati) get their name of 'pitati' from these related pd words.
