The Edfu Temple (237–57 BCE), a Ptolemaic temple dedicated to Horus and made of sandstone, is considered one of the best preserved ancient Egyptian temples [Wilkinson 2017]. French Egyptologist Émile Chassinet spent 40 years copying the hieroglyphs from the reliefs and walls, in order to preserve the eroding markings. More recently, the Edfu Project was begun by Dieter Kurth in 1986 and sponsored by the Göttingen Academy of Sciences from 2002 to 2017, with the goal of translating the Edfu texts. Eight large volumes of German translations along with transliterations of the hieroglyphs were published. The Edfu Database contains German translations, photographs, and clips from Chassinet’s work for portions of the Edfu Temple. An area known as the Cadastral text has a plethora of fractions, but the photographs are not available online at this time.

According to François Gaudard [2010, p. 173], Ptolemaic hieroglyphs, like those in the Edfu Temple, can be challenging to translate, even for Egyptologists. The number of hieroglyphic symbols in the Middle Kingdom (sources vary on its dating but converge around roughly 2040 to 1782 BCE) was about 760 while the number grew to several thousand signs during the Ptolemaic period (after Alexander the Great until roughly 200 CE). Gaudard mentions that a head hieroglyph represented the number seven “simply because the head has seven openings, namely, two eyes, two ears, two nostrils, and a mouth.” We conjecture that the 5-pointed star hieroglyph in Figure 14 is used for five. So, the middle portion of text could be read (left to right) as “at 37 $$\frac{1}{2}$$ $$\frac{1}{3}$$ by 25 $$\frac{2}{3}$$ $$\frac{1}{6}$$.” The hieroglyph in the bottom right corner is a determinative for "building” or “house.”

The 5-pointed star symbol as a representation for five seems to be confirmed by translations found in the Edfu Database. One example is a portion of text translated as “A large decorated gate is between them, at 26 $$\frac{2}{3}$$ by 10 (cubits). Its perfect height of 40 cubits extends from its head to the soles of its feet.” The hieroglyphs corresponding to “at 26 $$\frac{2}{3}$$ by 10 (cubits). Its perfect height of 40” can be seen in the two images (read right to left) in Figure 15.

Below are a few more photographs from the Edfu Temple. The first one, which is read from top to bottom and from right to left within each row, contains a four and a seven. It demonstrates how the Egyptians were concerned with aesthetics. Notice how the four strokes fit well in a single line while the seven is stacked in rows of four and three, respectively, and shares a row with another hieroglyph and a determinative stroke.

The three strokes indicate a plural noun since they appear underneath another hieroglyph.
