Seal Amulets, 4th to 11th Dynasties

A couple of amulets may be a Sha,
Also, Brunton thinks no. 23, "Hemi-cylinder seal-amulet in steatite with figure of Set (?)"

Budge's Hieroglyphic dictionary has, "Sha, a fabulous animal like a greyhound with a straight tail in the form of an axe", which we know is Set's representation in animal form.

Guy Brunton in Qua and Badari I declares of the most ancient times:

"It may be suggested that the name Shau is connected with Set who was called Sha in early times; and the town of Sha-sehotep (Shotb) is only a few miles north of Badari."

Brunton further notes:

"The most interesting point to notice is that in the second foundation the shrine is dual, though single in the first. Badari is in the nome of " The Two Gods." What the change in the number of the shrines implies, has to be worked out. A coupling of the worship of Set with that of Horus in the New Kingdom may just possibly be the explanation."

There are a great many prehistoric slate palettes featuring a dual theme, and possibly Set and Horus are being represented in them:

One even appears to have four heads...
The Petrie museum website has a photo of one

Even as late as the Second Intermediate Period, we see, as in a scarab from the Intermediate period, two falcons that represent Set and Horus. A Middle Kingdom pectoral shows two canine bodied entities to represent Set and Horus, aka "the two Lords".
