In 1914 the English Egyptologist, Sir William Flinders Petrie, (1853-1942), published a paper on the earliest known hieroglyphs. He showed 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 (13C 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 contains a number of seals. In this class, the sealings were nearly all seals of royal officials. Seal No. 75 reads ???eal of the stores of the estate, the granary of barley and spelt?? Petrie considers the columns of various animals, e.g., hippopotamus, lion, crocodile, etc, to be differently understood and interpreted.
