United Behedet

In Upper Egypt the hieroglyph symbol for Nome 17 was Zm-bhdt, united Behedet, and was linked with the symbol X. This X marked the where ecliptic and equator intersect at Spring Equinox. In a context where the year began in September as in Persia and Israel March would have been the 7th month. The circle was typically one of the symbols of the female (along with downward pyramid). This helps to explain why in the North Picene langiage the seventh letter is a circle with an X.
