Byzantium open sea Melos Sidon off Sounion Piraeus

The Homeward Stars

A voyage in six chapters, for Eric, on his sixty-second birthday

It is the autumn of 405 BC. The Athenian fleet has been destroyed at Aegospotami, and Lysander's Spartan triremes are closing on every city that ever paid tribute to Athens. Among those cities is Byzantium, where a certain Athenian astronomer, attached to the fleet to keep its star tables, has been left behind.

His name is Eric. He knows the sky better than any man alive, he has read more about old wars than is entirely healthy, and he has an eye for a well-built wall. In the chapters that follow he will need all three.

Each chapter ends with a problem. Solve it and the ship moves on. If you are stuck, ask for a hint; the sea is patient. At the end there is a feast, and a poem.

The Chain Across the Harbour

Byzantium, on the night the city changes hands

The Spartan party entered by the landward gate at dusk; by full dark the Athenian garrison was under guard and the harbour chain was up. Eric, who had been on the roof of the customs house with his sighting rods, was simply not counted.

One small merchant galley remained at the quay, its Byzantine owner willing to sail for a price. But the chain across the harbour mouth is a hand's breadth of iron, and it drops only on a signal from the Spartan officer of the watch.

That officer left his leather strap on the customs house table. It is a Spartan message, written on a strip wound around a rod, then unwound: a scytale. Read straight, it is nonsense. Wound around a rod of the right girth, it tells you exactly when the chain falls.

The strap reads

HRNSO ACFAN RHATS BALME OILOT

Write the letters into rows of the right width and read down the columns. When does the chain fall? Enter the single word that answers it.

A Spartan rod carried five letters around its girth. Write the twenty-five letters in five rows of five, then read each column top to bottom.

The Pole Without a Star

The Propontis and the open Aegean, three nights out

The Byzantine owner is a coastal man. He steers by headlands, and now there are none. On the third night, with cloud to the south and a Spartan patrol somewhere behind, he asks the astronomer to take the helm.

Eric knows what the Phoenicians have known for centuries: that the sky wheels around a point that does not move, and that if you keep that point on your right shoulder you will sail west all night without a landmark. The Greeks steer by the Great Bear, which is bright but swings wide. The Phoenicians steer by the Little Bear, which stays close to the hub.

But in this year the hub is empty. No star sits on it. The nearest bright one is in the Little Bear, and he must find it.

Find the pole star of 404 BC

Tap the star that lay nearest the celestial pole in Eric's lifetime. The chart shows the northern sky with the Great Bear at bottom, the Little Bear above, and the dragon between them.

Precession moves the pole through a full circle every 25,800 years. Polaris only earned its name in the last few centuries. In Eric's day the pole sat between Polaris and the brightest star in the bowl of the Little Bear, and closer to the second.

The People of Melos

A cove on the eastern side of Melos

They put in for water at Melos, the island Athens emptied twelve years ago. The men were killed, the women and children sold, and Athenian settlers moved into the houses. Now Lysander has thrown the settlers out in turn and told the surviving Melians they may come home.

Some have. At the spring above the cove Eric finds thirty of them, sunburnt, patient, and short of everything. An old woman who was sold at Piraeus in 416 and walked back across half the Aegean asks him, politely, who he is. When he says Athenian, nobody moves, and nobody speaks.

At length the old woman says that Melians have always tested strangers with a riddle, and that the answer will decide whether the water is his to take. She does not say what happens otherwise.

The old woman's riddle

I have no hands, yet I push a hundred oars.
I have no mouth, yet I sing in the rigging all night.
Athens counted me among its allies, and I changed sides without a word.
I can bring you home, or scatter you like the Melians.
What am I?

Every sailor's ally, and no one's friend. Think of what fills a sail.

The Letters Without Vowels

The harbour of Sidon, on the Phoenician coast, under Persian rule

The gale sets them down, nearly dismasted, on a coast Eric has read about but never seen: Phoenicia, the country of the purple dye and the cedar and the alphabet, whose cities pay tribute to the Great King and whose ships won Salamis for Persia and lost it.

A Greek galley in a Persian harbour in wartime is a problem for everyone. The harbour master wants to know whose ship it is and whose side. Eric's Byzantine owner, sensibly, has stopped speaking.

Eric asks for the merchant the Melian woman named. The harbour master smiles, hands him a potsherd with a line of Phoenician letters on it, and says that if the stranger can tell him which city the merchant's family came from, he will be believed. The Greeks, after all, borrowed these letters from the Phoenicians two centuries ago. A man who knows old things ought to be able to read them.

Eric remembers three things. The letters run from right to left. There are no vowels; the reader supplies them. And the Greek letters he learned as a child are the same signs, turned around and renamed.

The potsherd

𐤑𐤃𐤍

If the letters above show as blank boxes, the scribe's copy reads: sade, dalet, nun.

𐤀aleph, a glottal stop, later the Greek alpha
𐤁bet, the sound B
𐤃dalet, the sound D
𐤌mem, the sound M
𐤍nun, the sound N
𐤑sade, an emphatic S, which Greeks heard as S
𐤓resh, the sound R
𐤕taw, the sound T

Which Phoenician city does the potsherd name? Add the vowels yourself.

Read right to left you get S, D, N. It is a city on this very coast, the sister and rival of Tyre, and the harbour you are standing in.

Twenty Ships off Sounion

The Saronic Gulf, within sight of the temple of Poseidon

Off Cape Sounion, with the white temple on its cliff and Piraeus a morning's row beyond, they fall in with what is left of the Athenian navy: eight triremes under a captain called Conon's cousin, refitted at Samos and trying to slip home. Eric's galley is taken under their wing.

Then, at dawn, twenty Peloponnesian triremes come around the cape. The Athenian captain has one gift to offer against those odds: the fleet's astronomer, who has, he says, read every account of every sea fight since Salamis, and could describe the trick Phormio played at Naupactus in his sleep.

Eric is asked, three times, what the fleet should do. The rowers are waiting.

First: the enemy is forming a line abreast, bows toward you, twenty ships wide. You have eight.

The Feast at Piraeus

A house near the Cantharus harbour, the same evening

They had held the funeral in the winter. Everyone knew what Aegospotami meant for the men at Byzantium, and Eric's friends had said the words and poured the offering and gone home to grieve. Now a galley with a Phoenician sail and a cargo of purple comes alongside the quay, and the man on its deck is not dead at all.

There is a great deal of shouting. Then somebody remembers that there is a fish market forty paces away, and that the philosopher on the corner has been saying for years that the wise man eats no flesh, and that tonight, at least, he can be humoured.

Before the wine is mixed there is one last question, because it is Athens and there is always one last question.

The host's toast

"A trireme carries one hundred and seventy rowers on three levels," says the host, raising his cup. "Fifty-four thalamites low in the hull, fifty-four zygites on the middle bench, and on the top bench, in the open air, where the best men sit and see the sky, a certain number of thranites. Our friend has lived exactly that many years. How many?"

170 less 54 less 54.

The Song of Eric's Return

Sung by a hired poet at the end of the feast, as was customary, for a fee

Sing, Muse, of the man who was counted among the dead, who was left on the roof of the customs house at Byzantium with his rods and his tables while the city changed its masters, and who came home over the sea by the light of an empty pole. IIron lay across the harbour mouth, and Sparta held the shore. He took up the strap of the watch and wound it on a rod of the right girth, and the nonsense fell into rows, and the rows said: moonset. So under a chain still falling he slipped out into the dark. IIThree nights the cloud hung south of him and the headlands were gone. Then he did what the Sidonians do, and looked for the hub of the sky, and found no star there, only Kochab standing guard beside it, and he laid the Little Bear on his shoulder, and steered by the space between. IIIAt Melos the island was empty, and then it was not: thirty of the sold and scattered were home again at the spring. They asked him for one true answer, and he named the wind, which is no one's friend and everyone's ally, and had the water for free. IVEight days that wind drove him east to the coast of cedar and purple, and a Sidonian gave him three signs on a broken pot, and no vowels. He read them from right to left as a child reads its first alphabet, and the harbour laughed, and the walls were higher than any he would see again. VOff Sounion twenty prows came round the cape at first light, and a captain with eight ships turned to a man who had only read of battle. He said: wait for the wind, and let them wallow, and then go through. And they went through, and six of twenty were left on the sand. VISo he came into Piraeus with a Phoenician sail, and the friends who had mourned him stood on the quay and forgot to speak. They set out mullet and lentils and cakes of honey and sesame, and counted his years in rowers: the sixty-two who sit in the open air, on the top bench, where the best men sit, and see the sky. Many happy returns, Eric. May every voyage end at a table like this one.
