|Some basic images of the Egyptian god Ptah, who holds the power symbols of: Ra (ankh), Osiris (djed pillar), and Set (was scepter), who rose to power (see: supreme god timeline) during the Memphis recension, in the 2nd Dynasty (2890-2686 BC). |
The staff of Ptah consists of the "djed pillar", symbolic of the resurrective nature of Osiris, the "ankh", symbolic of the rebirth of the sun or the god Ra, and the "was scepter", symbolic of Set. Ptah, accordingly, is thrice-powerful god, supposedly, subsuming those of Ra, Osiris, and Set.
Apis | Osiris
The Apis served as the Ba (the spirit or physical manifestation) of the Egyptian god Ptah, chief god of the city Memphis. The Greek name "Panepi" is thought to derive from the Egyptian phrase Pth, the "Spirit of Ptah," but Panepi is not attested to as a god elsewhere in the literary evidence.
Herodotus describes the mystical nature of the birth of the Apis, where "a flash of light descends upon the cow from heaven, and this causes her to receive Apis" and the mother cow "is never afterwards able to have another [calf]." Upon the death of the Apis bull, it becomes identified with Osiris. Because of the divine nature of the bull's birth and its affiliation with Osiris, the bull's mother, hence, comes to be identified with Isis, goddess of motherhood and sorceress whose magic resuscitated the deceased Osiris. 
Hephaestus | Greece
In Greece, Ptah came to be called "Hephaestus" (see: god character rescripts); the following is one summary of this:
“The earliest recorded Egyptian versions of their own remote past date from Ramessid times. From this period dates the Turin Canon, which agrees substantially with Manetho's account. The oldest kings are definitely associated with Heliopolis, and there-fore the list ought to begin with the sun god, Re-Atum [see: Atum-Ra], or in Greek Helios. But in fact Manetho names ‘Hephaestus’ as the first ruler of Egypt, suggesting that this version was originally compiled in the 6th dynasty, the kings of which came from Memphis, the centre of worship of Ptah. Although Diodorus records what is primarily the Heliopolitan tradition, starting with Helios, it is clear that he is also aware of the Memphite theology since he records a variant genealogy of Hephaestus (Helios?), Cronus, and Osiris. It is possible that this owes something to Manetho, who may be included in the: ‘ενιοι δε των ίερεων’, a phrase which presumably refers otherwise to the priests of Memphis. The Greek god Hephaestus was identified with the Egyptian god Ptah, an identification aided by the fact that Ptah was noted as a craftsman, while Hephaestus was the god of smithying.”— Anne Burton (1973), Diodorus Siculus: a Commentary (pg. 71)
Egypt | Aigyptos | House of Ptah
In 2500BC, Egypt, in the old kingdom, was referred to as “Kmt” (hieroglyph) or “Kemet” (with syllables inserted), based on the term “keme”, meaning black soil, in contrast to the “red soil” of the desert, which was considered the “land of Set”.
In c.1150BC, Egypt, when Ptah became supreme god, came to be referred to as the “House of Ptah”, a reference to the god Ptah, who had become supreme god of Egypt in the years [add]. In other cultures, as this religious model was cross-culturally transmitted (see: god character rescripts), the god Ptah came to be called: “Jiapheta” (India, c.900BC), “Hephaestus” (Greece, c.600BC), “Vulcan” (Rome, c.400BC), and finally “Japheth” (Judea, 300BC),
In 1050 to 656BC, during the so-called “Judaic recension” (see: recension theory; supreme god timeline), the supreme gods were, generally speak, the following entities:
● YHWH / Yahweh
● Abraham | Ab-Ra-ham
● El [see: Neter]
● Ptah = “the Lord” = El (Ѻ)
● Osiris-Ra | Moses + Abraham
● Ptah-Atum | Japheth + Adam
some, as shown above, being rescripted, via the god-to-prophet rescript method, so to affect a god reduction towards monotheism. In this period, the name of Egypt was changed from Kemet (Old Kingdom, 3100BC) to House of Ptah or Egypt; this etymological transition is summarized as follows:
Ptah (Memphis, 2800BC) → Hikuptah (Amarna, 1300BC) → Hephaestus (Greek, 800BC) → Jiapheta (Indian, 800BC) → Aigyptos (Greek, 300BC) → AEgyptum (Latin, 500) → Egipte (Old English, 1150) → Egypt (English, c.1500)
The following are related quotes:
“Turning to the Egyptian sphere, though, again we have a connection. The name Japheth in old Hebrew consists of three consonants, ‘J-Ph-Th’. The ‘ph’ and ‘th’ sounds are linguistically equivalent to ‘p’ and ‘t’, so we can write the name as J-PT. In Hebrew, when combining the name of god with another word, one would use a ‘J’ for god's name, which usually appears in transliteration as ‘Ja’ [Ja-Pheth / god Ptah] or ‘Jo’ [Jo-seph / Joseph / god Geb]. In J-PT, the PT part of the name contains the same letters used for the name of the Memphite creator deity, Ptah, so Japheth would be the linguistic equivalent of the name ‘god-Ptah’. This is a typical form of Egyptian combination name, such as Atum-Re [Atum-Ra] or Re-Herakhte. It also suggests the frequently used Hebrew term ‘lord god’.”— Gary Greenberg (2000), 101 Myths of the Bible (pg. 75)
“Egypt: Old English Egipte ‘the Egyptians’, from French Egypte, from Greek Aigyptos ‘the river Nile, Egypt’, from Amarna Hikuptah, corresponding to Egyptian Ha(t)-ka-Ptah ‘temple of the soul of Ptah’, the creative god associated with Memphis, the ancient city of Egypt. Strictly, one of the names of Memphis, it was taken by the Greeks as the name of the whole country. The Egyptian name, Kemet, means ‘black country’ [compare: red country; desert, aka land of Set], in reference to the rich delta soil.”
