Ptolemy IV Philopator in the context of "Hugronaphor"

Coinage of the Ptolemaic kingdom was struck in Phoenician weight, also known as Ptolemaic weight (about 14.2 grams) which was the weight of a Ptolemaic tetradrachm. This standard, which was not used elsewhere in the Hellenistic world, was smaller than the dominant Attic weight (about 17.28 grams) which was the weight of standard Hellenistic tetradrachm. Consequentially, Ptolemaic coins are smaller than other Hellenistic coinage. In terms of art, the coins, which were made of silver, followed the example set by contemporary Greek currencies, with dynastic figures being typically portrayed. The Ptolemaic coin making process often resulted in a central depression, similar to what can be found on Seleucid coinage.

The Ptolemaic dynasty introduced standard coinage to Egypt, where pre-existing native dynasties made only very limited use of coins. Egyptian gold stater was the first coin ever minted in ancient Egypt around 360 BC during the reign of pharaoh Teos of the 30th Dynasty. These coins were used to pay salaries of Greek mercenaries in his service.

The Ptolemaic Decrees were a series of decrees by synods of ancient Egyptian priests. They were issued in the Ptolemaic Kingdom, which controlled Egypt from 305 BC to 30 BC. In each decree, the benefactions of the reigning pharaoh, especially towards the priesthood, are recognised, and religious honours are decreed for him.

Two decrees were issued under Ptolemy III Euergetes (the Decree of Alexandria and Decree of Canopus), another under Ptolemy IV Philopator (the Raphia Decree), and others under Ptolemy V Epiphanes (the Decree of Memphis and the two Philensis Decrees). Multiple copies of the decrees, inscribed on stone steles, were erected in temple courtyards, as specified in the text of the decrees.

Agathocles (Ancient Greek: Ἀγαθοκλῆς, flourished 3rd century BC, died 203/202 BC) was a Ptolemaic minister and together with his sister Agathoclea was very close to Egyptian king Ptolemy IV Philopator (r. 221–204 BC).

Horwennefer (Ancient Egyptian: ḥr-wnn-nfr "Horus-Onnophris"; Ancient Greek: Άροννώφρις Haronnṓphris) was an Egyptian who led Upper Egypt in secession from the rule of Ptolemy IV Philopator in 205 BC. No monuments are attested to this king but along with his successor, Ankhwennefer (also known as Chaonnophris or Ankhmakis), he held a large part of Egypt until 186 BC. Contemporary accounts suggest that Horwennefer was a Nubian. A graffito dating to about 201 BC on a wall of the mortuary Temple of Seti I at Abydos, in which his name is written Ὑργοναφορ (Hyrgonaphor), is an attestation to the extent of his influence and the ideology of his reign. He appears to have died before 197 BC.

The Abydene graffito, one of the few documents remaining from his reign, is written in Egyptian using Greek letters, the oldest testimony of a development which would end in the Coptic script replacing the native Egyptian demotic.

Berenice II Euergetis (267 or 266 – 221 BCE; Greek: Βερενίκη Ευεργέτις, Berenikē Euergetis, "Berenice the Benefactress") was queen regnant of Cyrenaica from 258 to 246 BCE and queen of Ptolemaic Egypt from 246 to 222 BCE as the wife of Ptolemy III. She is sometimes considered co-regent of her Ptolemaic husband.

She married Demetrius the Fair, thus giving him the throne of Cyrenaica, on the death of her father Magas in 250/249 BCE. After a short power struggle with her mother, Berenice married her half-cousin Ptolemy III, the third ruler of the Ptolemaic kingdom. This marriage led to the re-incorporation of Cyrenaica into the Ptolemaic empire. As queen of Egypt, Berenice participated actively in government, was incorporated into the Ptolemaic state cult alongside her husband and worshipped as a goddess in her own right. She is best known for sacrificing her hair as a votive offering, which led to the constellation Coma Berenices being named after her. Berenice was murdered by the regent Sosibius shortly after the accession of her son Ptolemy IV Philopator in 221 BCE.

Sosibius (Ancient Greek: Σωσίβιoς; floruit 221-204 BC) was the chief minister of Ptolemy IV Philopator (221–204 BC), king of Egypt. Nothing is known of his origin or parentage, though he may have been a son of Sosibius of Tarentum; nor is there any account of how he rose to power. He is first attested immediately after the accession of Ptolemy IV in 221 BC, exercising great influence over the 22-year old king alongside Agathocles, the brother of Ptolemy IV's mistress Agathoclea. He remained a major force throughout the reign and helped ensure the smooth succession of Ptolemy V Epiphanes in 204 BC. After that he disappears from the record.
