Ptolemaic Decrees

The Ptolemaic Decrees were a series of three decrees issued by the Hellenistic Ptolemaic dynasty, which ruled Egypt from 305 BC to 30 BC. The first decree was issued by Ptolemy III (the Decree of Canopus), the second by Ptolemy IV (The Memphis Stele), and the third by Ptolemy V. The Rosetta Stone is a well-known example of one of the texts; it was included in the Third Decree. Multiple copies of the decrees, inscribed on stone stelae, were erected in temple courtyards, as specified in the text of the decrees.

There exist three copies plus a fragment of the Decree of Canopus, two copies of the Memphis Decree (one imperfect), and two and a half copies of the text of the Rosetta Stone, including the copy on the Nubayrah Stele and a pyramid wall inscription with edits, or scene replacements, completed by subsequent scribes.
