Serabit el-Khadim proto-Sinaitic inscriptions

The Serabit el-Khadim proto-Sinaitic inscriptions are about 30 early alphabetic inscriptions in proto-Sinaitic script found at or in the vicinity of Serabit el-Khadim on the Sinai Peninsula.

Description
Romanus François 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 black and white photographs, hand-drawings and analysis of the previously published inscriptions, #346, 349, 350–354, and three new inscriptions, #355–368. At that time, #355 was still in situ at Serabit but had not been photographed by the previous Harvard Mission. In 1932, he wrote: "The present article was begun with the limited purpose of making known the new inscriptions discovered by the Harvard-Catholic University Joint Expedition to Serabit in the spring of 1930. In the course of this study, I perceived that some signs doubtful in the inscriptions already published were made clear by the new slabs, and I decided to go over the entire field again."

Table of inscriptions
All the inscriptions published between 1916 and 1936 were given identification numbers following those of Gardiner's initial 1916 publication. Gardiner's numbers 1–344 were objects from Sinai with unrelated Egyptian inscriptions, so the Proto-Sinaitic inscriptions numbering began at 345. Future scholars continued this numbering scheme for ease of reference.
