Berenice II Euergetis (267 or 266 BC – 221 BC, Berenikē Euergetis, "Berenice the Benefactress") was ruling queen of Cyrenaica from around 250 BC and queen and co-regent of Ptolemaic Egypt from 246 BC to 222 BC as the wife of Ptolemy III Euergetes.

One of the most formidable Ptolemaic queens, Berenice II's family background was unusually convoluted and bloody, even by Macedonian standards. Born in 267 BC, she was the daughter of the Cyrenaican king Magas and his wife Apama. In 249 BC, upon the death of Magas, her mother married her off to Demetrius the Fair, son of Demetrius Poliorcetes, who was invited to become king of Cyrenaica. Demetrius, however, was more interested in Apama than her daughter and, catching him in her mother's bed, Berenice stabbed him to death. Despite this, her legendary beauty prompted Ptolemy III of Egypt to marry her, in 244/3 BC, and the duo became the foremost "power couple" in the world. Berenice appears to have ruled Egypt quite capably during her husband's long campaigns of conquest. During one such campaign, she cut off her hair and dedicated it to Aphrodite for her husband's safe return. The hair mysteriously disappeared and was "discovered" in the heavens forming the constellation Coma Berenices. The tale entered legend as "The Lock of Berenice." She had six children, one of whom, Ptolemy IV, succeeded to the throne in 221 BC. Berenice originally ruled jointly with him but was soon murdered, probably at the instigation of her son. Gold and silver coins were minted in her name on both the Ptolemaic and Macedonian standards.

Depicts cornu­copia containing grain ear, pyramidal cake, and pomegranates, with grape cluster hanging from the rim of horn at left, bound with royal fillet with ends floating sinuously; all between two laureate pileus helmets of the Dioscuri with a dotted border.

Castor and Pollux (or Polydeukes) are twin half-brothers in Greek and Roman mythology, known together as the Dioscuri. Their mother was Leda, but they had different fathers; Castor was the mortal son of Tyndareus, the king of Sparta, while Pollux was the divine son of Zeus, who raped Leda in the guise of a swan. The pair are thus an example of heteropaternal superfecundation.

Pollux asked Zeus to let him share his own immortality with his twin to keep them together, and they were transformed into the constellation Gemini. The pair were regarded as the patrons of sailors, to whom they appeared as St. Elmo's fire.

The pileus (Ancient Greek: πῖλος, pîlos; also pilleus or pilleum in Latin) was a brimless felt cap worn in Ancient Greece, Etruria, Illyria (Pannonia), later also introduced in Ancient Rome. The pileus also appears on Apulian red-figure pottery.
