Serabit el-Khadim  Serabit el-Khadim ( ; also transliterated Serabit al-Khadim, Serabit el-Khadem) is a locality in the southwest Sinai Peninsula, Egypt, where turquoise was mined extensively in antiquity, mainly by the ancient Egyptians. Archaeological excavation, initially by Sir Flinders Petrie, revealed ancient mining camps and a long-lived Temple of Hathor, the Egyptian goddess who was favoured as a protector in desert regions. Thirty incised graffiti in a "Proto-Sinaitic script" shed light on the history of the alphabet. The mines were worked by prisoners of war from southwest Asia who presumably spoke a Northwest Semitic language, such as the Canaanite that was ancestral to Phoenician and Hebrew. After a century of study and the initial publication by Sir Flinders Petrie, researchers agree on the decipherment of a single phrase, cracked in 1916 by Alan Gardiner: לבעלת ' (to the Lady) [' (Lady) being a title of Hathor and the feminine of the title "" (Lord) given to the Semitic god], although the word " (loved) is frequently cited as a second word. The script has graphic similarities with the Egyptian hieratic script, the less elaborate form of the hieroglyphs. In the 1950s and 1960s it was common to show the derivation of the Canaanite alphabet from hieratic, using William Albright's interpretations of Proto-Sinaitic as the key. It was generally accepted that the language of the inscriptions was Semitic, that the script had a hieratic prototype and was ancestral to the Semitic alphabets, and that the script was itself acrophonic and alphabetic (more specifically, a consonantal alphabet or abjad). The word " (Lady) lends credence to the identification of the language as Semitic. However, the lack of further progress in decipherment casts doubt over the other suppositions, and the identification of the hieratic prototypes remains speculative. Romanus Francois Butin of Catholic University of America published articles in the "Harvard Theological Review" based on the 1927 Harvard Mission to Serabit and the 1930 Harvard-Catholic University Joint Expedition. His article "The Serabit Inscriptions: II. The Decipherment and Significance of the Inscriptions" provides an early detailed study of the inscriptions and some dozen B/W photographs, hand-drawings and analysis of the previously published inscriptions, #346, 349, 350-354, and three new inscriptions, #355-368.
