Horus, Serapis, and Dionysus

Horus

Horus is one of the most significant ancient Egyptian deities. He was worshiped from at least the late prehistoric Egypt until the Ptolemaic Kingdom and Roman Egypt. Different forms of Horus are recorded in history and these are treated as distinct gods by Egyptologists. These various forms may possibly be different perceptions of the same multi-layered deity in which certain attributes or syncretic relationships are emphasized, not necessarily in opposition but complementary to one another, consistent with how the Ancient Egyptians viewed the multiple facets of reality. He was most often depicted as a falcon, most likely a lanner falcon or peregrine falcon, or as a man with a falcon head.

The earliest recorded form of Horus is the tutelary deity of Nekhen in Upper Egypt, who is the first known national god, specifically related to the king who in time came to be regarded as a manifestation of Horus in life and Osiris in death. The most commonly encountered family relationship describes Horus as the son of Isis and Osiris, and he plays a key role in the Osiris myth as Osiris's heir and the rival to Set, the murderer of Osiris. In another tradition Hathor is regarded as his mother and sometimes as his wife. Horus served many functions, most notably being a god of kingship and the sky.

Horus was born to the goddess Isis after she retrieved all the dismembered body parts of her murdered husband Osiris, except his penis, which was thrown into the Nile and eaten by a catfish, or sometimes depicted as instead by a crab, and according to Plutarch's account used her magic powers to resurrect Osiris and fashion a golden phallus to conceive her son (older Egyptian accounts have the penis of Osiris surviving).

Once Isis knew she was pregnant with Horus, she fled to the Nile Delta marshlands to hide from her brother Set, who jealously killed Osiris and who she knew would want to kill their son. There Isis bore a divine son, Horus.

Serapis

Serapis or Sarapis is a Graeco-Egyptian god. The cult of Serapis was introduced during the 3rd century BC on the orders of Ptolemy I of Egypt as a means to unify the Greeks and Egyptians in his realm. The god was depicted as Greek in appearance, but with Egyptian trappings, and combined iconography from a great many cults, signifying both abundance and resurrection. A serapeum (Greek serapeion) was any temple or religious precinct devoted to Serapis. The cultus of Serapis was spread as a matter of deliberate policy by the Ptolemaic kings, who also built an immense serapeum in Alexandria.

However, there is evidence which implies that cult of Serapis existed before the Ptolemies came to power in Alexandria – a temple of Sarapis (or Roman Serapis) in Egypt is mentioned in 323 BC by both Plutarch (Life of Alexander, 76) and Arrian (Anabasis, VII, 26, 2). The common assertion that Ptolemy "created" the deity is derived from sources which describe him erecting a statue of Sarapis in Alexandria: this statue enriched the texture of the Sarapis conception by portraying him in both Egyptian and Greek style. Though Ptolemy I may have created the cult of Sarapis and endorsed him as a patron of the Ptolemaic dynasty and Alexandria, Sarapis was a syncretistic deity derived from the worship of the Egyptian Osiris and Apis (Osiris + Apis = Oserapis/Sarapis) and also gained attributes from other deities, such as chthonic powers linked to the Greek Hades and Demeter, and benevolence linked to Dionysus.

Serapis continued to increase in popularity during the Roman period, often replacing Osiris as the consort of Isis in temples outside Egypt. In 389, a Christian mob led by the Patriarch Theophilus of Alexandria destroyed the Alexandrian serapeum, but the cult survived until all forms of pagan religion were suppressed under Theodosius I in 391.

Dionysus 

Dionysus is the god of the grape harvest, wine-making and wine, of ritual madness, fertility, theater and religious ecstasy in ancient Greek religion and myth. 

Wine played an important role in Greek culture, and the cult of Dionysus was the main religious focus for its unrestrained consumption. His worship became firmly established in the seventh century BC. He may have been worshiped as early as c. 1500–1100 BC by Mycenean Greeks; traces of Dionysian-type cult have also been found in ancient Minoan Crete.

The origins of Dionysus are uncertain, and his cults took many forms; some are described by ancient sources as Thracian, others as Greek. In some cults, he arrives from the east, as an Asiatic foreigner; in others, from Ethiopia in the South. He is a god of epiphany, "the god that comes", and his "foreignness" as an arriving outsider-god may be inherent and essential to his cults. He is a major, popular figure of Greek mythology and religion, becoming increasingly important over time, and included in some lists of the twelve Olympians, as the last of their number, and the only god born from a mortal mother. His festivals were the driving force behind the development of Greek theater.
