In brief

  1. I.Eight often stands for a new beginning, one step beyond the completeness of seven, or for balance in all directions.
  2. II.Buddhism teaches the Noble Eightfold Path and honours eight auspicious symbols, and early Christians built octagonal baptisteries for the ‘eighth day’ of resurrection.
  3. III.Jews light candles for the eight nights of Hanukkah, while Chinese thought builds its cosmology on the eight trigrams of the ba gua.
  4. IV.In Chinese the word for eight sounds like the word for prosperity, which has made it the luckiest number in much of East Asia.

In each tradition

  • Buddhism

    The Noble Eightfold Path, right view, intention, speech, action, livelihood, effort, mindfulness and concentration, is the fourth of the Four Noble Truths. The eight-spoked wheel stands for it, and Tibetan Buddhism honours eight auspicious symbols.

  • Christianity

    Early Christians called Sunday, the day of the resurrection, the ‘eighth day’, the first day of a new creation. Many early baptisteries were built with eight sides to express this.

  • Judaism

    Hanukkah lasts eight nights, with one more light kindled each evening. Boys are circumcised on the eighth day after birth (Genesis 17:12), and Shemini Atzeret, ‘the eighth day of assembly’, follows the seven days of Sukkot.

  • Islam

    The Qur’an says that on the Day of Judgement eight angels will bear the throne of God (69:17), and hadith speak of eight gates of paradise. The Dome of the Rock in Jerusalem, completed in 691–692, is an octagon.

  • Hinduism

    The eight guardians of the directions protect the four cardinal and four intermediate points, and the goddess Lakshmi is worshipped in eight forms. The Yoga Sutras of Patanjali describe eight limbs of yoga.

  • Daoism

    The ba gua, eight trigrams of broken and unbroken lines, underlie the Yijing (I Ching) and appear on Daoist robes, mirrors and temple ceilings. The Eight Immortals are among the most popular figures of Chinese religion.

  • Shinto

    In Japanese myth eight often means ‘many’, as in the eight million kami, and the sacred mirror of the imperial regalia is called Yata no Kagami, the ‘eight-span mirror’.

  • Ancient Egyptian religion

    At Hermopolis the Ogdoad, eight primeval gods in four male and female pairs, were believed to have existed in the waters before creation.

Where it comes from

  • Eight is the first cube (two times two times two), and the doubling of four, which gave it a sense of balance and stability.
  • Adding the four intermediate directions to the four cardinal ones gives eight, a full circle of orientation used in Indian, Chinese and Islamic architecture.
  • In Jewish and Christian thought eight follows the completed week of seven, so it naturally became the number of a new start.
  • In Chinese the sound of the number, not its shape or arithmetic, explains much of its modern popularity.

Chapter I

Paths and symbols

Eight is a number of balance and of new beginnings. It is four doubled, the eight points of the compass, and it is seven plus one, the step that begins a new cycle after a completed one. Different traditions have drawn on each of these ideas.

In Buddhism eight is the number of the path. The Buddha’s Four Noble Truths end with the truth that there is a way out of suffering, and that way is the Noble Eightfold Path: right view, right intention, right speech, right action, right livelihood, right effort, right mindfulness and right concentration. These are not steps taken one after another but parts of a single training, often grouped under wisdom, ethical conduct and meditation. The wheel of the Dharma, one of the oldest Buddhist symbols, is usually drawn with eight spokes for the eight parts of the path.

Buddhist art also has its eight auspicious symbols, especially prominent in Tibet and the Himalaya: the parasol, the pair of golden fish, the treasure vase, the lotus, the conch shell, the endless knot, the victory banner and the wheel. Each has its meaning, the parasol for protection, the conch for the sound of the teaching spreading in all directions, the endless knot for the interconnection of all things. They decorate temples, prayer flags and household objects, and Indian traditions knew similar sets of eight lucky signs before Buddhism adopted them.

Hindu tradition places eight guardians at the points of the compass, four cardinal and four intermediate, and worships the goddess of prosperity, Lakshmi, in eight forms. The Yoga Sutras of Patanjali describe yoga in eight limbs, from ethical restraints to the final state of absorption. In Japan eight often simply means ‘very many’: the old texts speak of the eight million kami, and one of the three sacred treasures is the eight-span mirror.

Chapter II

The eighth day

For Jews and Christians, eight follows the holy seven. In Judaism a baby boy is circumcised on the eighth day after birth, and the festival of Sukkot, seven days long, is followed by Shemini Atzeret, the ‘eighth day of assembly’. The most famous Jewish eight is Hanukkah. The books of Maccabees tell how Judah Maccabee and his followers recaptured the Temple in Jerusalem from the Seleucid king Antiochus IV and rededicated it in 164 BCE with an eight-day celebration, which 2 Maccabees links to the eight days of Sukkot. The familiar story of a single jar of pure oil that burned for eight days appears centuries later, in the Babylonian Talmud. Today families light the eight-branched lamp, the hanukkiah, adding one light each night, with a ninth helper candle to kindle the rest.

Early Christians gave eight a new meaning. Jesus rose, the Gospels say, on the first day of the week, the day after the Sabbath. Writers of the second century and later began to call it the ‘eighth day’, a day beyond the week of creation that pointed to a new world. Baptism, in which a Christian died and rose with Christ, was its sacrament, and so many baptisteries were built with eight sides. A verse inscription traditionally attributed to Ambrose of Milan in the fourth century explains that the octagonal font suits the place where new life is given. The octagonal baptisteries of Florence, Ravenna and the Lateran in Rome are among the best known. Christian writers also recalled that eight people were saved in Noah’s ark, an image the First Letter of Peter connects with baptism. Western tradition usually counts eight Beatitudes, the blessings that open the Sermon on the Mount in Matthew’s Gospel, and some writers linked them with the eighth day as well.

Islamic architecture took up the octagon too. The Dome of the Rock in Jerusalem, completed in 691–692, is built on an eight-sided plan, probably influenced by earlier Christian shrines in the region. The Qur’an speaks of eight angels carrying God’s throne on the Last Day, and hadith describe eight gates of paradise, a theme repeated in eight-sided pavilions and gardens. In ancient Egypt, priests at Hermopolis taught that eight primeval gods, the Ogdoad, existed in the dark waters before the world began.

Chapter III

Trigrams and good fortune

In China eight sits at the centre of cosmology. The ba gua, the ‘eight trigrams’, are all the possible combinations of three lines, each either unbroken (yang) or broken (yin). Tradition credits their discovery to the legendary sage Fuxi. Doubled, they form the sixty-four hexagrams of the Yijing, or Book of Changes, the classic of divination honoured by both Confucians and Daoists. Arranged in a circle, often around the yin-yang sign, the trigrams map the directions, the seasons and the members of a family, and they appear on Daoist robes, temple ceilings and the octagonal mirrors hung over doorways. The Eight Immortals, a group of Daoist saints, are among the most popular subjects of Chinese art.

Eight is also China’s luckiest number, mainly for reasons of sound: ba, eight, resembles fa, to prosper. The Beijing Olympic Games opened on 8 August 2008 at eight minutes past eight in the evening, and telephone numbers, addresses and car plates full of eights sell at a premium. In Japan eight is lucky for a different reason: the character 八 opens out towards the bottom, a shape called suehirogari, ‘spreading wider towards the end’, which suggests growing prosperity. This is popular custom rather than religious teaching, but it shows how a number’s meaning can grow from language as much as from scripture.

Myths and facts

  • The claim

    The miracle of oil lasting eight days is told in the books of Maccabees.

    What is known

    The books of Maccabees describe the rededication of the Temple and an eight-day festival, which 2 Maccabees compares to Sukkot. The story of a single jar of oil that burned for eight days first appears centuries later in the Babylonian Talmud.

  • The claim

    The figure eight lying on its side was a religious symbol of eternity.

    What is known

    The infinity sign was introduced by the English mathematician John Wallis in 1655, and its origin is unclear. It is not an ancient sacred eight, though it is often confused with the ouroboros and other older symbols of endlessness.

  • The claim

    Eight is lucky throughout Asia for religious reasons.

    What is known

    Its luck in China comes mainly from the sound of the word, and in Japan from the shape of the character 八, which widens towards the bottom like a growing fortune. Buddhist and Daoist eights are a separate matter.

Questions people ask

What is the Noble Eightfold Path?

It is the Buddha’s path to the end of suffering, made up of right view, intention, speech, action, livelihood, effort, mindfulness and concentration. The eight are usually grouped under wisdom, ethical conduct and meditation.

Why does Hanukkah last eight days?

The books of Maccabees say that the Temple was rededicated with an eight-day festival in 164 BCE. The later rabbinic story explains the eight days by a miracle of oil.

Why is eight a lucky number in China?

Its name, ba, sounds like fa, the word for becoming rich. For this reason the Beijing Olympics opened on 8 August 2008 at 8.08 p.m., and phone numbers and number plates full of eights command high prices.
