Alexander III (late July, 356 BC–June 10, 323 BC), commonly known as Alexander the Great, in Greek "Megas Alexandros", King of Macedon (336 BC-323 BC), was one of the most successful military commanders of the ancient world. Following the unification of the multiple city states of Ancient Greece under the rule of his father, Philip II of Macedon, Alexander conquered the Persian Empire, including Anatolia, Syria, Egypt, Bactria and Mesopotamia, and extended the boundaries of his own empire as far as India. Alexander integrated non-Greeks into his army and administration, leading some scholars to credit him with a “policy of fusion.”

May all mortals from now on live like one people in concord and for mutual advancement. Consider the world as your country, with laws common to all and where the best will govern irrespective of tribe. I do not distinguish among men, as the narrow-minded do, both among Greeks and Barbarians. I am not interested in the descendance of the citizens or their racial origins. I classify them using one criterion: their virtue.
"Alexander's Oath given at Opis", as quoted by Nikos Martis

March from Oria to Pura takes 60 days, and many of his men and animals die along the way. Alexander is alone offered water at one point, which he grandly pours out to show his solidarity with his men.

"There is no part of my body but my back which has not a scar..."

In 332-331 BC Alexander was welcomed as a liberator in Egypt and was pronounced the son of Zeus by Egyptian priests of the god Ammon at the Oracle of the god at the Siwah oasis in the Libyan Desert. He founded Alexandria in Egypt, which would become the prosperous capital of the Ptolemaic dynasty after his death.

Dhu al-Qarnain is Alexander the Greek, the king of Persia and Greece, or the king of the east and the west, for because of this he was called Dhul-Qarnayn [meaning, "the two-horned one"]... Ibn Hisham

If I were not Alexander, I should wish to be Diogenes. After Diogenes of Sinope who was lying in the sun, responded to a query by Alexander asking if he could do anything for him with a reply requesting that he stop blocking his sunlight. As quoted in "On the Fortune of Alexander" by Plutarch

If it were not my purpose to combine barbarian things with things Hellenic, to traverse and civilize every continent, to search out the uttermost parts of land and sea, to push the bounds of Macedonia to the farthest Ocean, and to disseminate and shower the blessings of the Hellenic justice and peace over every nation, I should not be content to sit quietly in the luxury of idle power, but I should emulate the frugality of Diogenes. But as things are, forgive me Diogenes, that I imitate Herakles, and emulate Perseus, and follow in the footsteps of Dionysos, the divine author and progenitor of my family, and desire that victorious Hellenes should dance again in India and revive the memory of the Bacchic revels among the savage mountain tribes beyond the Kaukasos… As quoted in "On the Fortune of Alexander" by Plutarch

Matt Ridley speaks about how ideas have sex and the mating of these ideas create hybrid ideas that have cultural consequences. In history the expansion of Roman power and influence into Jewish Culture in Palestine allowed for an exchange and mating of cultural ideas that led to very consequential hybrids. One powerful hybrid being the religion of Christianity and the rise of Monotheism globally. It was Roman authority, Jewish mysticism and pagan mystery occults that gave birth to Christianity. It was Roman Crucifixion, A Jewish Jesus and Pagan familiarity with divine humans that were ingredients to a soup that would set much of human history on a certain trajectory. The Divine Augustus a Son of God would be replaced in some 300 years with the Divine Jesus the Son of God. It was a hybrid of Rome & Jerusalem and carried with it a hybrid theology from paganism and Judaism. The idea of God as Trinity (3 Gods who are 1) is a mix of  pagan Monotheism. A hybrid idea of cultural consequence.
Without the mating of Rome and Jerusalem there would be no Christianity. It is clearly nourished by human history and not set apart from it.

  Even logistically without the infrastructure of the Roman Empire it would have been impossible for Christianity and the Apostle Paul’s message to spread to the extent it did. The genius of the formation of early Christianity was to take Roman punishment and humiliation as the spiritual and theological significance of their movement and thereby turning death into life and tragedy into a triumph. It was a brilliant form of populism. It was a story that touched the masses where many lived lives of hardship compared to the ruling Roman elite. Jesus was a god of the people not of the state. Not until Christianity became popular in the Roman world and it became politically expedient for the Emperor Constantine to use this religion to solidify his power and unify the empire. In doing so Constantine gave the death blow to Hellenism (which had a fatal turn of events many years before in the Maccadean Revolt 166 BC) and now through Roman power gave rise to the Monotheistic State. An idea from Jerusalem to Rome that birthed a new era of political Monotheism that would not be challenged until the historical currents of the Renaissance, the Reformation and the Enlightenment.
