ALEXANDER THE GREAT EXPLORES INDIA
 STILL greater light was shed on the size of the world by Alexander the Great on his famous expedition to India, by
which he almost doubled the area of the world known to the people of his time. It was just sixty years after
Xenophon had made his way right across Asia to the shoes of the Black Sea when Alexander resolved to break, if
possible, the power of the Persians.
The great Persian Empire extended from the shores of the Mediterranean right away to the east, far beyond the
knowledge of the Greeks. Indeed, their knowledge of the interior of Asia was very imperfect, and Alexander's
expedition was rather that of an explorer than of a conqueror. How he overthrew the Persians and subdued an
area as large as Europe in the space of twelve years reads like a romance rather than fact, and it is not for
us to tell the story in detail. Rather let us take up the story after Alexander has fought and conquered the
Persians twice, besieged Tyre, taken the Phœnician fleet, occupied Egypt, marched across the desert and
crossed the Euphrates, passed over the plain and followed the Tigris to near Nineveh, where he crossed that
river too, fought another famous battle over the Persians, which decided the fate of King and Monarchy and
opened to him the capitals of Babylon and Susa, wherein the immense treasures of the Persian Empire were
stored. King of all Asia, he sat on the throne of the Persian kings under a golden canopy in the palace of
 So far the whole expedition was over country known, if imperfectly, to the Greeks. Now we have to follow the
conquering hero more closely as he leads us into an unknown land away to the east, known as "the farthest
region of the inhabited world towards the east, beyond which lies the endless sandy desert void of
inhabitants." And all the while the great land of India lay beyond, and beyond again was China, and away far
over the ocean sea lay America—and they knew it not.
Alexander was a young man yet, only twenty-six. It was four years since he had left Europe, and in that short
time he had done wonders. He had conquered the whole eastern half of the Persian Empire. Now he resolutely
turned his face to the unknown east and started forth on an expedition of exploration.
Following the main highway from Media, which to-day leads from Teheran, capital of modern Persia, into the
land of the Turkomans and the borders of Russia, he found himself between the great salt desert and the
mountains, which to-day mark the frontier of Persia. Suddenly, to his great surprise, the Caspian Sea came
into sight. It seemed about the same size as the Black Sea, and he concluded it was connected with the Sea of
Azof; though the men of his day were certain enough that it was the most northern of four great gulfs
connected with the outer ocean which flowed round the world.
Onwards towards the east he marched with his great army. To conciliate the tribes through which he passed, he
adopted Persian dress. This annoyed his Greek countrymen, but, "as they admired his other virtues, they
thought he might be suffered to please himself a little and enjoy his vanity."
Arrived at the modern boundary between Persia, Afghanistan, and Russia, he and his men pushed on across
Afghanistan, by the caravan route that had long existed
 from the shores of the Caspian, by modern Herat, Kandahar,
which still bears the conqueror's name, and Kabul to India. Their way lay through deep snow, deeper than they
had ever seen before; and by the time they had reached the mountains of Kabul it was midwinter.
Between Alexander and India still lay the lofty range of the Hindu Koosh or Indian Caucasus. But before going
south toward India, he turned northwards to explore the unknown country which lay about the river Oxus. They
found the Oxus, a mighty stream, swollen with melting snows. There were no boats and no wood to build them, so
Alexander pioneered his men across in "life-preservers" made out of their leather tent coverings and stuffed
with straw. This river impressed the Greeks even more than the Euphrates and Tigris, as it impressed many an
explorer and poet since these early days. Let us recall Matthew Arnold's famous description of the Oxus, now
seen for the first time by the Greeks.
"But the majestic river floated on,
Out of the mist and hum of that low land,
Into the frosty starlight,—he flow'd
Right for the polar star, past Orgynje
Brimming, and bright, and large; then sands begin
To hem his watery march and dam his streams,
And split his currents; that for, many a league
The shorn and parcell'd Oxus strains along
Through beds of sand and matted rushy isles—
Oxus, forgetting the bright speed he had,
In his high mountain-cradle in Pamere,
A foil'd circuitous wanderer—till at last
The long'd for dash of waves is heard, and wide
His luminous home of waters opens, bright
And tranquil, from whose floor the new-bathed stars
Emerge, and shine upon the Aral Sea."
Here in this valley the Greeks met more determined opposition than they had yet encountered since entering
 Asia, and over two years were occupied in reducing this single district (now Bokhara and Turkestan) to
submission, though it was only some three hundred and fifty miles square, and in one single year Alexander had
conquered a kingdom over one thousand miles in width.
It was not till the spring of 827 B.C. that he was ready to cross the Hindu Koosh and begin the great
expedition into India. The night before the start Alexander discovered that his troops were now so heavily
laden with spoils that they were quite unfit for the long march. So in the early morning, when they were all
ready to start, he suddenly set fire to his own baggage, and, giving orders that all his men were to do the
same, the army started for the passes of the lofty mountain range. And—
" . . . . as a troop of pedlars from Kabul
Cross underneath the Indian Caucasus,
That vast sky neighbouring mountain of milk snow;
Crossing so high, that, as they mount, they pass
Long flocks of travelling birds dead on the snow,
Choked by the air, and scarce can they themselves
Slake their parch'd throats with sugar'd mulberries—
In single file they move, and stop their breath,
For fear they should dislodge the o'erhanging snows."
The banks of the river of Kabul were reached at last. Sending part of the army by the now famous Kyber Pass
toward the Indus, Alexander himself undertook to subdue the mountain tribes and get control of the Chitral
passes. The shepherds of this region opposed him vigorously, but swiftly and pitilessly the King of Asia
sacked their peaceful homes, and city after city fell to him as he advanced towards the boundaries of Kashmir.
At last the valley of the Indus was reached. A bridge of boats was hastily thrown over, and Alexander and his
army passed to the other side.
Porus, the ruler of the country between the Indus
 and the river Hydaspes (Jehlam), sent presents of welcome to the invader, including three thousand animals for
sacrifice, ten thousand sheep, thirty elephants, two hundred talents of silver, and seven hundred horsemen.
The new king was also greeted with presents of ivory and precious stones. Even from far Kashmir came greetings
to Alexander, whose fame was spreading rapidly. He now entered the Punjab, the "Land of the Five Rivers." But
on the other side of the river Hydaspes a different reception awaited him.
There the king (Porus) had assembled a sturdy, well-disciplined troop to dispute the passage of the river,
which separated the new King of Asia from his territory. But under cover of a mighty thunderstorm Alexander
contrived to cross, though the river was rushing down yellow and fierce after the rains. Secretly the Greeks
put together their thirty-oared galleys hidden in a wood, and utterly surprised Porus by landing on the other
side. In their strange wanderings the Greeks had fought under varying conditions, but they had never faced
elephants before. Nevertheless, they brilliantly repulsed an onslaught of these animals, who slowly retreated,
"facing the foe, like ships backing water, and merely uttering a shrill, piping sound." Despite the elephants
the old story was repeated, civilised arms triumphed over barbarians, and the army of Porus was annihilated,
his chariots shattered, and thirty-three thousand men slain.
The kingdom beyond the Hydaspes was now Alexander's. Ordering a great fleet of rafts and boats to be built for
his proposed voyage to the mouth of the Indus, he pushed on to complete the conquest of the Five Stream Land,
or the Punjab—the last province of the great Persian Empire. This was India—all that was known at
this time. The India of the Ganges valley was beyond the knowledge of the Western world—the Ganges
 unknown to the Persians. And Alexander saw no reason to change his mind.
"The great sea surrounds the whole earth," he stoutly maintained.
But when he reached the eastern limit of the Punjab and heard, that beyond lay a fertile land "where the
inhabitants were skilled in agriculture, where there were elephants in yet greater abundance and men were
superior in stature and courage," the world stretched out before him in an unexpected direction, and he longed
to explore farther, to conquer new and utterly unknown worlds!
But at last his men struck. They were weary, some were wounded, some were ill; seventy days of incessant rain
had taken the heart out of them.
"I am not ignorant, soldiers," said Alexander to the hesitating troops, that during the last few days the
natives of this country have been spreading all sorts of rumours to work upon your fears. The Persians in this
way sought to terrify you with the gates of Cilicia, with the plains of Mesopotamia, with the Tigris and
Euphrates, and yet this river you crossed by a ford and that by means of a bridge. By my troth, we had long
ago fled from Asia could fables have been able to scare us. We are not standing on the threshold of our
enterprise, but at the very close. We have already reached the sunrise and the ocean, and unless your sloth
and cowardice prevent, we shall thence return in triumph to our native land, having conquered the earth to its
remotest bounds. I beseech you that ye desert not your king just at the very moment when he is approaching the
limits of the inhabited world."
But the soldiers, "with their heads bent earthwards," stood in silence. It was not that they
would not follow him beyond the sunset; they could not. Their tears began to flow,
sobs reached the ears of Alexander, his anger turned to pity, and he wept with his men.
 "Oh, sir," at last cried one of. his men, "we have done and suffered up to the full measure of the capacity of
mortal nature. We have traversed seas and lands, and know them better than do the inhabitants themselves. We
are standing now almost on the earth's utmost verge, and yet you are preparing to go in quest of an India
unknown even to the Indians themselves. You would fain root out, from their hidden recesses and dens, a race
of men that herd with snakes and wild beasts, so that you may traverse as a conqueror more regions than the
sun surveys. But while your courage will be ever growing, our vigour is fast waning to its end. See how
bloodless be our bodies, pierced with how many wounds and gashed with how many scars! Our weapons are blunt,
our armour worn out! We have been driven to assume the Persian dress! Which of us has a horse? We have
conquered all the world, but are ourselves destitute of all things."
The conqueror was at last conquered. The order to turn back was reluctantly given by the disappointed king and
leader. It was received with shouts of joy from the mixed multitudes of his followers, and the expedition
faced for home. Back they marched through the new lands where no less than two thousand cities had owned his
sway, till they came to the banks of the river where the ships were building. Two thousand boats were ready,
including eighty thirty-oared galleys.
It was now September 326 B.C.
Nearchus from Crete was made Admiral of the new fleet, which at dawn one October morning pushed out upon the
river Hydaspes and set sail downstream towards the unknown sea, Alexander standing proudly on the prow of the
royal galley. The trumpets rang out, the oars moved, and the strange argosy, "such as had never been seen
before in these parts," made its way down the unknown river to the unknown sea. Natives swarmed to the banks
 of the river to wonder at the strange sight, marvelling specially to see horses as passengers on board! The
greater part of the army followed the ships on land, marching along the shores. At last the waters of the
Hydaspes mingled with those of the Indus, and onwards down this great river floated the Persian fleet.
Alexander had no pilots, no local knowledge of the country, but with his "unquenchable ambition to see the
ocean and reach the boundaries of the world," he sailed on, "ignorant of everything on the way they had to
pass." In vain they asked the natives assembled on the banks how far distant was the sea; they had never heard
of the sea! At last they found a tide mixing its salt waters with the fresh. Soon a flood-tide burst upon
them, forcing back the current of the river, and scattering the fleet. The sailors of the Mediterranean knew
nothing of the rise and fall of tides. They were in a state of panic and consternation. Some tried to push off
their ships with long poles, others tried to row against the incoming tide; prows were dashed against poops,
oars were broken, sterns were bumped, until at last the sea had flowed over all the level land near the river
Suddenly a new danger appeared! The tide turned and the sea began to recede. Further misfortunes now befell
the ships. Many were left high and dry; most of them were damaged in some way or another. Alexander sent
horsemen to the seashore with instructions to watch for the return of the tide and to ride back in haste so
that the fleet might be prepared.
Thus they got safely out to sea on the next high tide.
Alexander's explorations were now at an end. Leaving Nearchus to explore the seacoast at the mouth of the
Indus, he left the spot near where the town of Hyderabad now stands, and turned his face toward the home he
was never to reach. We must not linger over his terrible
 coast journey through the scorching desert of Beluchistan:
the billows of sand, the glare of the barren sea,
the awful thirst, the long hungry marches of forty miles a day under the burning Eastern sun.
A SKETCH-MAP OF ALEXANDER'S CHIEF EXPLORATORY MARCHES FROM ATHENS TO HYDERABAD AND GAZA.
Our story is one of discovery, and we must turn to Nearchus, Admiral of the fleet, left behind at the mouth of
the Indus to explore the coast to the Persian Gulf, where he was to meet Alexander if possible. Shortly after
the fleet had emerged from the mouth of the Indus a violent south-west monsoon began to blow and Nearchus was
obliged to seek shelter in a harbour, which he called the port of Alexander, but which to-day is known as
Karachi, the most western seaport of India. The waters of the Indian Ocean were quite unknown to the Greeks,
and they could only coast along in sight of land, anchoring at different points for the men to land and get
 food. Past the wild barren shores of Beluchistan they made their way; the natives subsisted on fish entirely
even as they do to-day—even their huts being made of fish bones and their bread of pounded fish.
They had but one adventure in their five months' cruise to the Persian Gulf, but we have a graphic account of
how the terrified Greeks met a shoal of whales and how they frightened the whales away. Here is the story. One
day towards daybreak they suddenly saw water spouting up from the sea, as if being violently carried upwards
by whirlwinds. The sailors, feeling very frightened, asked their native guides what it meant. The natives
replied that it was caused by whales blowing the water up into the air. At this explanation the Greek sailors
were panic-stricken and dropped the oars from their hands. Nearchus saw that something must be done at once:
So he bade the men draw up their ships in line as if for battle and row forward side by side towards the
whales, shouting and splashing with their oars. At a given signal they duly advanced, and when they came near
the sea-monsters they shouted with all their might and blew their trumpets and made all possible noise with
their oars. On hearing which, says the old story, "the whales took fright and plunged into the depths, but not
long after came to the surface again close to the sterns of the vessels and once more spouted great jets of
water. Then the sailors shouted aloud at their happy and unlooked-for escape," and Nearchus was cheered as the
saviour of the fleet. It is not uncommon to-day for steamers bound from Aden to Bombay to encounter what is
called a "school of whales" similar to those which alarmed the fleet of Nearchus in the year 323 B.C.
The expedition was completely successful and Nearchus pioneered his fleet to the mouth of the Euphrates.
But the death of Alexander the Great and the confusion
 that followed set back the advance of geographical discovery in this direction for some time.
ALEXANDRIA IN PIZZIGANI'S MAP, FOURTEENTH CENTURY.
Alexandria—one of the many towns founded by Alexander—had become the world centre of the learned from
Europe, Asia, and Africa. Its position was unrivalled. Situated at the mouth of the Nile, it commanded the
Mediterranean Sea, while by means of the Red Sea it held easy communication with India and Arabia.
When Egypt had come under the sway of Alexander, he had made one of his generals ruler over that country, and
men of intellect collected there to study and to write. A library was started, and a Greek, Eratosthenes, held
the post of librarian at Alexandria for forty years, namely, from 240&endash;190 B.C. During this period he made a
collection of all the travels and books of earth description—the first the world had ever
known—and stored them
 in the Great Library of which he must have felt so justly proud. But Eratosthenes did more than this. He was
the originator of Scientific Geography. He realised that no maps could be properly laid down till something
was known of the size and shape of the earth.
By this time all men of science had ceased to believe that the world was flat; they thought of it as a perfect
round, but fixed at the centre in space. Many had guessed at the size of the earth. Some said it was forty
thousand miles round, but Eratosthenes was not content with guessing. He studied the length of the shadow
thrown by the sun at Alexandria and compared it with that thrown by the sun at Syene, near the first cataract
of the Nile, some five hundred miles distant, and, as he thought, in the same longitude. The differences in
the length of these two shadows he calculated would represent one-fiftieth of the circumference of the earth,
which would accordingly be twenty-thousand miles. There was no one to tell him whether he had calculated right
or wrong, but we know to-day that he was wonderfully right. But he must know more. He must find out how much
of this earth was habitable. To the north and south of the known countries men declared it was too hot or too
cold to live. So he decided that from north to south, that is, from the land of Thule to the land of Punt
(Somaliland), the habitable earth stretched for some three thousand eight hundred miles, while from east to
west—that is, from the Pillars of Hercules (Straits of Gibraltar) to India—would be some eight
thousand miles. All the rest was ocean. Ignoring the division of the world into three continents, he divided
it into two, north and south, divided by the Mediterranean and by a long range of mountains intersecting the
whole of Asia.
Then the famous librarian drew a map of the world for his library at Alexandria, but it has perished with all
 the rest of the valuable treasure collected in this once celebrated city. We know that he must have made a
great many mistakes in drawing a map of his little island world which measured eight thousand miles by three
thousand eight hundred miles. It must have been quaintly arranged. The Caspian Sea was connected with a
Northern Ocean, the Danube sent a tributary to the Adriatic, there was no Bay of Biscay, the British Isles lay
in the wrong direction, Africa was not half its right size, the Ganges flowed into the Eastern Ocean, Ceylon
was a huge island stretching east and west, while across the whole of Asia a mountain chain stretched in one
long unbroken line. And yet, with all his errors, he was nearer the truth than men three centuries later.
