The earliest "Proto-Sinaitic" inscriptions are mostly dated to between the mid-19th (early date) and the mid-16th (late date) century BC.
"The principal debate is between an early date, around 1850 BC, and a late date, around 1550 BC. The choice of one or the other date decides whether it is proto-Sinaitic or proto-Canaanite, and by extension locates the invention of the alphabet in Egypt or Canaan respectively."
The evolution of "Proto-Sinaitic" and the various "Proto-Canaanite" scripts during the Bronze Age is based on rather scant epigraphic evidence;
it is only with the Bronze Age collapse and the rise of new Semitic kingdoms in the Levant that "Proto-Canaanite" is clearly attested (Byblos inscriptions 10th – 8th century BC, Khirbet Qeiyafa inscription c. 10th century BC).
The Sinai inscriptions are best known from carved graffiti and votive texts from a mountain in the Sinai called Serabit el-Khadim and its temple to the Egyptian goddess Hathor (ḥwt-ḥr). The mountain contained turquoise mines which were visited by repeated expeditions over 800 years. Many of the workers and officials were from the Nile Delta, and included large numbers of Canaanites (i.e. speakers of an early form of Northwest Semitic ancestral to the Canaanite languages of the Late Bronze Age) who had been allowed to settle the eastern Delta.
Most of the forty or so inscriptions have been found among much more numerous hieratic and hieroglyphic inscriptions, scratched on rocks near and in the turquoise mines and along the roads leading to the temple.
The date of the inscriptions is mostly placed in the 17th or 16th century BC.
Four inscriptions have been found in the temple, on two small human statues and on either side of a small stone sphinx. They are crudely done, suggesting that the workers who made them were illiterate apart from this script.
In 1916, Alan Gardiner, using sound values derived from the alphabet hypothesis, translated a collection of signs as לבעלת lbʿlt (to the Lady)
Only a few inscriptions have been found in Canaan itself, dated to between the 17th and 15th centuries BC. They are all very short, most consisting of only a couple of letters, and may have been written by Canaanite caravaners or soldiers from Egypt. They sometimes go by the name Proto-Canaanite, although the term "Proto-Canaanite" is also applied to early Phoenician or Hebrew inscriptions, respectively.

The inscriptions are graphically very similar to the Serabit inscriptions, but show a greater hieroglyphic influence, such as a glyph for a man that was apparently not read alphabetically: The first of these (h1) is a figure of celebration [Gardiner A28], whereas the second (h2) is either that of a child [Gardiner A17] or of dancing [Gardiner A32]. If the latter, h1 and h2 may be graphic variants (such as two hieroglyphs both used to write the Canaanite word hillul "jubilation") rather than different consonants.
Hieroglyphs representing, reading left to right, celebration, a child, and dancing. The first appears to be the prototype for h1, while the latter two have been suggested as the prototype for h2.
Some scholars (Darnell et al.) think that the רב rb at the beginning of Inscription 1 is likely rebbe (chief; cognate with rabbi); and that the אל ʾl at the end of Inscription 2 is likely ʾel "(a) god".
Brian Colless has published a translation of the text, in which some of the signs are treated as logograms (representing a whole word, not just a single consonant) or rebuses [Antiguo Oriente 8 (2010) 91]
[V] "Excellent (r[ʾš]) banquet (mšt) of the celebration (h[illul]) of ʿAnat
(ʿnt). ʾEl (ʾl) will provide (ygš) [H] plenty (rb) of wine (wn) and victuals (mn)
for the celebration (h[illul]). We will sacrifice (ngṯ) to her (h) an ox (ʾ) and
(p) a prime (r[ʾš]) fatling (mX)."
This interpretation fits into the pattern in some of the surrounding Egyptian inscriptions, with celebrations for the goddess Hathor involving inebriation.
The term Proto-Canaanite is also used when referring to the ancestor of the Phoenician or Paleo-Hebrew script, respectively, before some cut-off date, typically 1050 BC, with an undefined affinity to Proto-Sinaitic.
While no extant inscription in the ″Phoenician alphabet″ is older than c. 1050 BC, "Proto-Canaanite" is a term used for the early alphabets as used during the 13th and 12th centuries BC in Phoenicia. However, the Phoenician, Hebrew, and other Canaanite dialects were largely indistinguishable before the 11th-century BC. The "Proto-Canaan" was first found in 2012, when during the excavations of the south wall of the Temple Mount by the Israeli archaeologist Eilat Mazar in Jerusalem on a storage jar made of pottery. Inscribed on the pot are some big letters about an inch high of which only five are complete and traces of perhaps three additional letters written in Proto-Canaanite script.
The Proto-Sinaitic inscriptions were studied by Alan Gardiner who, based on a short bilingual inscription on a stone sphinx, identified the inscriptions as Semitic, reading mʾhbʿl as "the beloved of the Lady" (mʾhb "beloved", with the second b and the final t of bʿlt "Lady" missing).
William Albright in the 1950s and 1960s published interpretations of Proto-Sinaitic as the key to show the derivation of the Canaanite alphabet from hieratic, leading to the commonly accepted belief that the language of the inscriptions was Semitic and that the script had a hieratic prototype.
The Proto-Sinaitic inscriptions, along with the contemporary parallels found in Canaan and Wadi el-Hol, are thus hypothesized to show an intermediate step between Egyptian hieratic script and the Phoenician alphabet. Brian Colless (2014) notes that 18 of the 22 letters of the Phoenician alphabet have counterparts in the Byblos syllabary, and it seems that the proto-alphabet evolved as a simplification of the syllabary, moving from syllabic to consonantal writing, in the style of the Egyptian script (which did not normally indicate vowels); this goes against the Goldwasser hypothesis (2010) that the original alphabet was invented by ignorant miners in Sinai.
According to the "alphabet theory", the early Semitic proto-alphabet reflected in the Proto-Sinaitic inscriptions would have given rise to both the South Arabian script and the Proto-Canaanite script by the time of the Bronze Age collapse (1200–1150 BCE).
The theory centers on Albright's hypothesis that only the graphic form of the Proto-Sinaitic characters derive from Egyptian hieroglyphs, and that they were given the sound value of the first consonant of the Semitic translation of the hieroglyph (many hieroglyphs had already been used acrophonically in Egyptian):
For example, the hieroglyph for pr ("house") (a rectangle partially open along one side, "O1" in Gardiner's sign list) was adopted to write Semitic /b/, after the first consonant of baytu, the Semitic word for "house".
According to the alphabet hypothesis, the shapes of the letters would have evolved from Proto-Sinaitic forms into Phoenician forms, but most of the names of the letters would have remained the same.
Below is a table synoptically showing selected Proto-Sinaitic signs and the proposed correspondences with Phoenician letters. Also shown are the sound values, names, and descendants of the Phoenician letters.
