Proto-Sinaitic script
There have been two major discoveries of inscriptions of the Proto-Sinaitic script. The first was in the winter of 1904–1905 in Sinai by Hilda and Flinders Petrie, dated to circa 1700–1400 BC. The second find was more recently in 1999 in Middle Egypt by John and Deborah Darnell. This is dated to the 18th century BC.
