This representation of Seshat and Thoth from the Temple of Ramses III is one of many found in Egypt. While there are different stories about the exact relationship between Thoth and Seshat, historical evidence shows they worked together as scribal partners. They were thought to both train and guide their scribes in their capacity as deities of writing and wisdom.
Many kings invoked these two together. For example, there is an image of a relief shared in Cracking the Code: The Rosetta Stone Decipherment by Richard Parkinson, of Ptolemy offering a pallet in a cartouche-shaped inkwell to Thoth, Seshat, and seven falcon-headed gods who are called the utterances. "These deities personify the written word, and are described as having 'caused memory to begin because they wrote'," writes Parkinson. He also shared a passage from that relief that "extols the invention of writing and expresses its wide multi-balance cultural significance in ancient Egypt, from administration to upholding the cosmic order." It is shared below, exactly as the decipherment of this passage appears in the book. It tells the story of how important these scribal partners were to the Egyptians.
These mighty ones created writing in the beginning
In order to establish heaven and earth in their moment
… Lords of the art of acting exactly.
A mooring post for those who travel on mud,
Craftsman of knowledge,
Leaders of teaching.
Nurses of the person who fashions perfect words,
Lords of the standard, rulers of accounts,
Whose true work is everything that ensures the well-being
Of the entire land;
Shepherds of the whole world,
Who steer perfectly without falling into water,
Fulfilling the need of all that is in all that is not,
Reassuring the hearts of the gods, and taking care of the established world,
It's watchmen, who watch without sleeping, performing the corvee duties of the fields,
Excellent ones who bring the rulership of the land,
Who reckon the confines of the four corners of the sky,
Who provide the offering tables of the great gods,
And the fields of the official,
Who guide everyone to their share,
Judging truthfully without those bribes on which everyone else relies in their trade.
The air speaks with his forefathers,
When they have passed from the heart:
A wonder of their excelling fingers,
So that friends can communicate when he sees them,
And one man can hear another without seeing him!
