North, south, east and west: how ancient civilisations found their bearings before the compass

Why did the ancient Chinese associate north with power? What led early Muslims to pray to the south? And what role did winds have to play in our understanding of directions? Jerry Brotton takes us on a journey through the history of the four points of the compass

Writing in his philosophical work the New Organon in 1620, the English scientist and philosopher Sir Francis Bacon famously identified China’s three great inventions, “which were unknown to the ancients, and of which the origin, though recent, is obscure and inglorious; namely printing, gunpowder and the magnet. For these three have changed the whole face and state of things throughout the world.”

Much has been written about the historical impact of printing and gunpowder. But there’s been far less emphasis on the magnet, and how (using lodestones to magnetise iron needles) it enabled the ‘obscure’ invention of the magnetic compass during the Han dynasty in the third century BC. This technology enabled China and, subsequently, other societies to navigate and orientate themselves according to the four points of the compass: north, east, south and west.

We tend to think about these directions and the art of navigation as a consequence of the invention of the compass, but this is not in fact the case. The ancient history of direction and its relationship to the magnetic compass is altogether more surprising.

How ancient civilisations understood east and west

Thousands of years before the discovery of the compass, early human societies observed the sun rising in the direction we now call ‘east’ and watched it setting in the direction now known as ‘west’. East to west was probably the earliest prime axis that people understood by simply watching the sun’s path across the sky. The worship of the sun, or heliolatry, characterised ancient Egyptian worship of solar gods: Horus (the rising sun), Ra (the noon sun) and Osiris (the dying or setting sun).

This initial east-west solar axis was gradually followed by the understanding of another axis. This one ran vertically from north to south, and could be identified by observing the sun and stars. At noon the sun is always due south in the northern hemisphere and due north in the southern hemisphere.

Living in the northern hemisphere, you can also look up at the stars and find north according to Polaris, the North or Pole Star. If you live in the southern hemisphere, that direction is identified by Polaris Australis, the South Star.

The four cardinal directions

By combining the two axes – east-west horizontally and north-south vertically – ancient societies created the basic framework for what we now call the four cardinal directions. The word ‘cardinal’ comes from the Latin cardinalis, which can mean something (or someone) of fundamental importance. That’s why, in the Roman Catholic church, it refers to a priest ranking beneath only the pope.

The names for these four directions were inspired by the human body: our front and back, left and right, even top and bottom. In many ancient languages, ‘front’ and ‘back’ are synonymous with east and west. In Hebrew, east – qedem or mizrach – also means ‘forward’ or ‘front’, while ‘west’ – achor – is a synonym for ‘behind’. In ancient Chinese, the pictograph for north, bĕi, represents two people back to back. The dark and cold north is synonymous with the ‘back’ of the body, while the ‘front’ looks southwards (nán), in the direction of light and warmth.

The earliest surviving record that we know of that names the four cardinal directions was inscribed on a clay tablet during the first great Mesopotamian empire, the Akkadian dynasty (c2350–2150 BC). It is a rudimentary topographical map known as the ‘Gasur map’, showing an agricultural estate. At the top left is IM-kur, ‘east’; at the bottom left is IM-mar-tu, ‘west’; and to the centre left IM-mir, ‘north’.

The prefix ‘IM’ refers to winds, not astronomical observations. Other Mesopotamian texts describe four principal winds forming a diagonal cross, equivalent to the modern directions of north-west, north-east, south-east and south-west. When the cuneiform text on the map is read from top to bottom, IM-mir, the direction from which the regular north-western winds blow, is the prime orientation.

What this shows is that the farmers cultivating the land more than 4,000 years ago understood the four cardinal directions in terms of wind direction and changeable climatic conditions. Why? Because they were crucial for the cultivation of crops and could mean the difference between feast and famine.

The importance of the winds

Ancient Greek philosophy and science inherited the Mesopotamian preoccupation with winds. Mythical personifications of the four directions as gods first appear in the ancient works of Homer (c800 BC). His celebrated epic poems, the Iliad and Odyssey, both mention four deities representing cardinal winds.

Boreas, the north wind, is possibly an archaic variant of ‘mountains’ or ‘roaring’. Notos, the south wind, derives from ‘moist’. Eurus, the east wind, comes from the ‘brightness’ of sunrise. The western wind of Zephyrus stems from the ‘gloom’ of sunset.

Later Greek philosophers offered a more naturalistic account of direction. Aristotle’s Meteorology (c350 BC) includes the earliest known geometrical diagram of cardinal directions according to wind systems, depicting eight principal winds in his conception of the Earth.

The Romans adopted many of the Greek terms for directions based on winds, and introduced some new Latin words. North came first, named borealis or septentriones, a reference to the ‘seven stars’ of Ursa Major (which appears to rotate around the northern star, Polaris).

South was given several new terms, including australis (‘harsh’ or ‘sharp’ – thanks to the harsh heat and hot, sharp winds) or meridionalis (from ‘midday’). West was occidentalis (‘falling’ or ‘passing away’) and east was orientalis (‘rising’ or ‘originating’, as in the sun). So, when we speak of being ‘disoriented’, we are literally saying we are unable to find the east.

The role of Judaism and Christianity

These ideas and terms were accepted until the ninth century, when a radical change took place that changed the names of the cardinal directions. This happened under Charlemagne (748–814), emperor of much of the northern part of Europe. In attempting to unify the continent, Charlemagne initiated many political, economic and educational reforms. This included abandoning winds as a means of classifying directions and renaming the four directions using proto-Germanic words, derived from Indo-European roots.

Nord (north) came from the proto-Indo-European term, nórto-s – ‘lower’, or to the ‘left’ (of the rising sun looking east). Est (east) drew on the Indo-European austo-s – ‘light’ or ‘shine’ (as in the morning). Sund (south) derived from an archaic term for the sun, sú-n-to-s, referring to the south as the direction of the midday sun. Oëst (west) took its name from the proto-Indo-European uestos with its many meanings of the evening, including red (as in the setting sun). Versions of these words are now recognisable in most modern European vernacular languages.

The impact of these evolving ideas of the cardinal directions underpinned early theological belief across various cultures. Jewish and Christian theology revered the east as the prime cardinal direction of worship and celebration. The story begins in Genesis: God “planted a garden eastward in Eden” (Genesis 2:8).

The messiah’s second coming is predicted as arriving from the east, “For as the lightning cometh out of the east, and shineth even unto the west; so shall also the coming of the Son of Man be” (Matthew 24:27). Mizrach, or east, thus became the Jewish direction of prayer.

Early Christianity expanded the Jewish mizrach by developing the Latin term Ad orientem – ‘to the east’ – to understand east as its sacred direction. The idea can be seen on medieval Christian maps, such as the mappa mundi housed in Hereford Cathedral. Here the cardinal directions are represented on its outer ring from the top, moving clockwise, from oriens (east), meridiens (south), occidens (west) to septentrio (north).

The Garden of Eden is shown at the top, then time flows downwards through images of Old Testament empires, the birth of Christ and the rise of Rome, with Jerusalem at the centre. It ends at the westernmost point of Gibraltar at the bottom of the map.

The differences of early Islamic maps

Where east sat at the top of early Christian maps for theological reasons, on many early Islamic maps south was the prime direction. This was because most of the societies that first converted to Islam lived directly north of Mecca. As a result, believers prayed due south, a practice that oriented their world maps accordingly.

On a map dated 1297 (copied from the 10th-century geographer Muhammad al-Istakhri), the world is oriented with south at the top. Africa is a claw extending deep into the Indian Ocean, and the vertical bar running from top right downwards is the Nile, flowing into the Mediterranean with three islands: Cyprus, Crete and Sicily.

Europe is shown below, including Muslim Spain (al-Andalus). The map’s finest detail lies at the heart of the Muslim empire, whose various administrative districts are demarcated in red. Arabia sits in the centre of the map with the holy sites of Mecca and Medina.

Why China put north at the top

While east and south defined the theological directions of Judaism, Christianity and Islam, in China north sat at the top of their world maps, hundreds of years before Europe adopted such a convention. In Chinese belief, the emperor was the ‘Son of Heaven’, the earthly manifestation of the supreme deity inhabiting the Pole Star.

The emperor looked ‘down’ south on his subjects from an elevated position on high in the north, while they looked ‘up’ northwards to him. ‘South’ (nan) was expressed in its pictograph as a liana plant, evoking the luxuriant vegetation of the south as viewed from the drier, colder northern latitudes. But north remained the direction from which imperial power and authority emanated.

For centuries, China was a global leader in the technology of navigation – and it was only in the 12th century that the magnetic compass started to appear in the Mediterranean for use in navigation. How these compasses moved west is still unclear. But they were decisive in enabling Christian navigators to develop sailing charts known as ‘portolans’ to navigate across, first, the Mediterranean, and then the Atlantic and Indian oceans.

Maps of European exploration

Yet though their explorations were facilitated by a Chinese technology, Europe an explorers didn’t initially follow the Chinese convention of placing north at the top of their maps. Eight years after Christopher Columbus’s momentous voyage to the Americas in 1492–93, Juan de la Cosa, owner of Columbus’s flagship, La Santa María, drew a map showing the new ‘discoveries’ in the west.

The writing on the map suggests that it should be oriented with west at the top – one of the few world maps to ever privilege ‘west’ as its cardinal direction. The west briefly became the cardinal direction – until European scholars, who tended to revere the classics, chose to mimic the ancient Greek practice of placing north at the top.

Juan de la Cosa’s map also features a ‘compass rose’ in the middle of the Atlantic, a symbol of the key role that the instrument was to play in the coming centuries.

Soon, with the European age of discovery gathering momentum, the magnetic compass would well and truly triumph. Many of us may have naturally assumed that the compass gave us the words we use for the cardinal directions – north and south, east and west. Yet, as the long and colourful history of our relationship with orientation and navigation proves, it was the other way round.
