I love Catholic and Orthodox art and iconography---it makes me feel at home.
Originally, Cleopatra ruled with her father Ptolemy XIII and later with her brothers, Ptolemy XIII and Ptolemy XIV, whom she married as per Egyptian custom, but eventually she became sole ruler.
No children were born from her union with her two brothers, but she did bear a son [Caesarion] to Julius Caesar, who was later elevated to co-ruler in name only.
Cleopatra represented herself as the reincarnation of the Egyptian goddess ‘Isis’, and was given the title of “Queen of Kings” by Mark Anthony. Her son ‘Caesarion’ was also given many titles, including ‘god’, ‘Son of god’ and ‘King of Kings’ and was depicted as Horus the son of Isis. It was after the assassination of Caesar in 44 BC, that Cleopatra coupled up with Mark Anthony and in 40 BC she bore to him the twins Cleopatra Selene II and Alexander Helios/Heli, and later on another son, Ptolemy Philadelphus.
In late 34 BC, at the Donations of Alexandria, shortly after Anthony had conquered Armenia, Cleopatra and Caesarion were crowned rulers of Egypt and Cyprus. Alexander Helios, their six-year-old son, was crowned ruler of Aemenia, Media and Parthia; Cleopatra Selene II, Heli’s six-year-old twin sister, was crowned ruler of Cyrenaica and Libya, and Ptolemy Philadelphus, the younger of their three children was crowned ruler of Phoenicia, Syria and Cilicia.
Isis was the most popular goddess from the time of Psamtik 1 (663-610 B.C) till the coming of Christianity, her cult appealed to the Greeks and Romans alike and when Egypt came under Roman rule, her cult spread through much of Europe. By the time of Jesus, the chief centre of her worship was in Rome.
Isis is commonly depicted with Horus the child (Harpocrates) on her lap, and today, it is impossible to distinguish between the late pagan and early Christian figures of the mother and child, [Isis and Horus---Mary and Jesus] it’s almost as though the old Pagan Queen was stripped of her garments and clothed with the new covering of Christianity.
