In 1914 the English Egyptologist, Sir William Flinders Petrie, (1853-1942), published a paper on the earliest known hieroglyphs. His purpose was to show what the construction and the general sense of the inscriptions on primitive stone cylinder seals were by means of comparison and statistical grouping. Linguistically he considered them scarcely intelligible, and used the Pyramid Texts, thirteen centuries later, as a basis expecting differences in the grammar, uses of writing, and words. He made hand-drawn copies of 72 of the cylinder inscriptions which were divided into eight classes. Each class contained a number of seals.The Theth class of cylinder inscriptions is connected with the Gods' names, and may be a term of prayer or of devotion. No. 33 reads ???ike unto Niet?? No.34 as ???ike unto Sekhmet?? Petrie suggests 'theth' means 'like unto'.
