33–Number of Completion

“Thirty-three is an ancient number of completion: the age when Christ was crucified; the years in which King David reigned. It also marks the number of divinities in the public festivals of the Persian Empire, and in the Hindu tradition three sets of eleven deities appear frequently as an auspicious pantheon of thirty-three. In Muslim tradition the ninety-nine beautiful names of God are recited with rosaries made from thirty-three prayer beads each used thrice, while the Hizb al-Wiqaya is a prayer of personal protection collected from thirty-three verses that invoke Koranic protection and divine names.

In broader cultural contexts, the number was chosen by Dante to structure his Divine Comedy (composed of three sets of thirty-three chapters); it expresses the number of spiritual ranks within Freemasonry; and the blows with which Shakespeare records death being delivered to Julius Caesar (‘When think you that the sword goes up again? Never, till Caesar’s three and thirty wounds be well avenged’).”

Lord Russell on Mathematics

“Mathematics may be defined as the subject in which we never know what we are talking about, nor whether what we are saying is true.”

The Splitting of a Hair into 40 Parts

“The splitting of a hair into forty parts was believed in the magically inclined early times to have been achieved by the six great physicians of antiquity–Plato, Hippocrates, Socrates, Aristotle, Pythagoras, and Galen. The physicians then used it to make a ladder in which science could ascend to the heavens, but there they failed to find a cure for death and returned to earth. Sometimes their number is extended by allowing King Philip II of Macedon to join this band.”

A Pantheon of 9

“In the Indo-Aryan West, 9 was always a most propitious number, for each aspect of a ruling trinity could be multiplied by 3 to create a pantheon of 9. It is not difficult to see that this was the likely origin for our choirs of nine angels, nine heavenly spirits and nine muses. The number also has an innate reference to the nine months in which a child is created within the womb.”

6 Physicians of Antiquity

“These six physicians were heroes of the medieval era, both to the Christian West and the Muslim East. Dante places them amongst the classical poets in the outer circle of hell, which was set aside for virtuous pagans–a place of green fields overlooked by a castle with seven gates for the seven virtues.”

The Four Hundred

“’The Four Hundred’ is the nickname for the social elite of New York, an alliance of old landed families, financial speculators, manufacturers and entrepreneurs who had assimilated European social manners and snobbery in the late nineteenth century. The overlooked the divisions of the Civil War, delighted in transatlantic marriages with the nobility of Europe, and guarded themselves from ‘new money’ coming in from the West, especially those who put too much crushed ice in their wine. The concept of the Four Hundred was popularized by Ward McAllister, the Beau Brummel of Manhattan, who coined the expression from the number who could be comfortably entertained, and felt at ease, in Mrs. Astor’s ballroom.”

1,003 Conquests of Don Giovanni

“Leporello, manservant of the fictional rake Don Giovanni (Don Juan), revealed that his master made 1,003 sexual conquests in his Spanish homeland…as well as 640 in Italy, 231 in Germany, 100 in France, and 91 in Turkey. Of course, it must be remembered that Leporello’s purpose was to gently persuade Donna Elvira not to put too much trust in his master–and to amuse an operatic audience. Still, Don Giovanni’s figures stack up well alongside his historic rivals. Casanova claimed to have slept with a mere 122 women. Byron (who wrote his own Don Juan) raced through more than 300 women (plus numerous rent boys and transvestites) before his early death in Greece, aged 36.”

Homer’s City of 100 Gates

“Homer’s chosen image for power was to describe Thebes, the capital of ancient Egypt, as a city of 100 gates; and from out of each one, at any moment, might pour 200 men riding chariots. Egyptian Thebes was known by its inhabitants as Waset. It should not be confused with Thebes in central Greece, a small but ancient Bronze Age city locked into an unprofitable rivalry with Athens and with its own numerical associations ever since Aeschylus wrote the play Seven Against Thebes.”

Two Sevens Clash

“Two Sevens Clash was the debut album from Culture, the roots reggae band led by Joseph Hill and produced in Kingston, Jamaica, by Joe Gibbs. Its title refers to the date of 7.7.1977—the day when ‘two sevens met’—which the Rastafarian prophet Marcus Garvey predicted would be a day of chaos and apocalypse. As the liner notes of the album read: ‘One day Joseph Hill had a vision, while riding a bus, of 1977 as a year of judgement—when two sevens clash—when past injustices would be avenged. Lyrics and melodies came into his head as he rode, and thus was born the song Two Sevens Clash which became a massive hit in reggae circles both in Jamaica and abroad. The prophecies noted by the lyrics so profoundly captured the imagination of the people that on July 7, 1977—the day when the sevens fully clashed (seventh day, seventh month, seventy-seventh year) a hush descended on Kingston; many people did not go outdoors, shops closed, an air of foreboding and expectation filled the city.’”
