It has been rare to find ancient ink pots that honor Seshat but there were likely many of them in the heydey of her scribal popularity. This one can be found at The Lourve but it is difficult to find more information about it.
In Cracking the Codes, author Richard Parkinson shares an image of a related item that makes me think that Seshat emblems on scribal tools were probably believed to be fortunate and blessed. One scribal palette with Seshat on it was described this way: As "part of a limestone funerary scribal pallet." At the top of the inkwell, there was still traces of red paint. "No inscription survives," he writes, "but a figure of Seshat is incised on the right side of the upper surface. The goddess holds a papyrus staff and has on her head her usual insignia of a rosette surmounted by upside-down horns, of uncertain significance."
I hope I can find out more about the image featured on this page. The image was found through Wikimedia and Creative Commons. One thing is for sure, the name is awesome: The Adoration of Seshat.
