In the 1350 BC correspondence of 382 letters, called the Amarna letters, the prostration formula is usually the opening subservient remarks to the addressee, the Egyptian pharaoh.
The formula is based on prostration, namely reverence and submissiveness.
The formula is often repetitive, or multi-part, with parts seeming to repeat and can go forward in a typical standard format.
However, the prostration formula may also be duplicated in a similar format at the end of a letter, or a foreshortened part of the formula may be entered, for effect, in the middle of a letter.
Reverse: This letter contains all the uses of "dirt, ground, chair, and footstool", seldom found in one letter.
