It was found in the Serapeum of Saqqara by Auguste Mariette[1] and later moved to The Louvre, where it is still.

The stela was intended to commemorate the death of an Apis bull occurred in this year and its author, the Priest of Ptah and Prophet of Neith, Pasenhor (B), was the performer of the funerary rites.

[2] The first part of the stela reflects its original purpose:[3] This god (i.e. the Apis) was introduced to his father Ptah (i.e. was "enthroned"), in the Year 12, fourth month of the second season, fourth day, of King Aakheperre Shoshenq (V), given life.

May he grant life, prosperity, health, and joy of heart to his beloved son, the prophet of Neith, Pasenhor.After that, Pasenhor begins to trace back along his genealogy for sixteen generations, until about the end of the 20th Dynasty:[4] Pasenhor's genealogy is quite important since he was a member of the royal family and could claim common ancestors with many pharaohs of the 22nd Dynasty.

Thanks to the stela, we know more about the dynasty's origin and chronology, as well as the name of some otherwise unattested royal wives such as Karomama A, Tashedkhonsu and Kapes.
