What Homer’s Odyssey Teaches Us About Nostos

What’s Homer got to do with the sitcom Friends?

Over the past ten or fifteen years, journalists have contacted me time and again with questions about nostalgia. More often than not, they want to know the same thing: Why do we keep rewatching Friends? Why do we return to the same books, films, songs, and places, even when we know them by heart?

The obvious answer is that familiar things comfort us in uncertain times. That is true. But I have come to think there is a deeper answer—one that, almost three thousand years ago, Homer already understood.

If Homer’s Iliad is the epic of kleos (glory), his Odyssey is the epic of nostos (homecoming). As a psychiatrist and the author of a book on the emotions, I have been writing about nostalgia for many years. But only recently did I begin to see the Odyssey through that same lens.

The word nostalgia was coined in 1688 by the Swiss medical student Johannes Hofer. A portmanteau of nostos and another Greek word, algos (‘pain’ or ‘ache’), it originally referred to the homesickness of Swiss mercenaries fighting in flat and foreign lands. Military physicians blamed the condition, among others, on ear and brain damage from the constant clanging of cowbells. Today, of course, we no longer think of nostalgia as a mental illness but as a natural, common, and often beneficial emotion.

Although the word is relatively recent, the feeling is ancient. No writer understood it more profoundly than Homer.

When we first meet Odysseus, he is not blinding the Cyclops or resisting the Sirens. He is sitting alone on the shore of Calypso’s island, gazing out to sea and weeping. Calypso has offered him everything that human beings are supposed to desire. She is beautiful and deeply in love with him. More significantly, she promises him eternal life with eternal youth. Despite all this, he daily returns to the same lonely place by the water and pines for Ithaca.

At first sight, his yearning seems irrational. Ithaca is a small, rocky island. His wife Penelope has grown older. His palace has been overrun by arrogant suitors. Why exchange paradise for hardship, mortality, and uncertainty?

Because what Odysseus longs for is not a better life, but his own life.

This is what makes the scene so moving. Odysseus does not simply long for a place in his past. He longs for the life that belongs to him: his wife, his son, his kingdom, his mortality—in short, his identity. Ithaca is not merely a destination but the place in which he can return to being himself.

Later in the story, the Phaeacian bard Demodocus sings of the Trojan War. Odysseus, who is in disguise, covers his face and weeps. Homer compares his grief to that of a woman throwing herself upon the body of her fallen husband, before she is dragged away into slavery. Only then does Odysseus reveal his identity and begin to tell the tale of his wanderings. As he reclaims his story, his voice blends with that of Homer. Memory becomes narrative, and narrative begins to heal memory.

Virgil echoed the famous scene at the beginning of the Aeneid, the foundational epic of Rome. Arriving in Carthage, Aeneas sees murals depicting the fall of Troy. He too breaks down into tears, before telling his story. Mourning the loss of his Trojan kin, he cries out, Sunt lacrimae rerum et mentem mortalia tangunt: ‘These are the tears of things, and mortal things touch the mind.’

Neither was nostalgia limited to Mycenaean princes. In 586 BCE, Babylonian forces destroyed Jerusalem and the First Temple, forcing many Jews into exile in Babylon. In the Bible, these Babylonian captives lament the loss of their homeland, in verses later put to music by Boney M: ‘By the rivers of Babylon, there we sat down, Yea, we wept, when we remembered Zion.’ 

Different peoples, different ages, different homes—but always the same tears. Nostalgia may be a seventeenth-century coinage, but the feeling is as old as humanity itself.

Today, psychologists understand nostalgia not as a mental disorder or disturbance but as an emotional resource. Nostalgia strengthens our sense of self and identity by anchoring our present in a larger narrative and reconnecting us with the people and places that have shaped us. In fact, nostalgia can be thought of as the counterpart of anticipation, and seems to serve the same purpose. The hauntings of times gone by, and the imaginings of times to come, strengthen us in lesser times.

This is one reason so many of us return to Friends. Those of us who are old enough often say that we miss a world before mobile phones and social media, when friends met spontaneously, conversations stretched late into the evening, and no one thought of ghosting you. The Berlin Wall had fallen, the Cold War was over, and many of us were riding high on the Wind of Change. There is a lot of truth in that. But I suspect we are also longing for something more personal. We are remembering a time in our lives when connection seemed fuller, the future seemed more open, and we ourselves were younger. Friends becomes a doorway not only onto that lost world, but also onto the person who inhabited it.

We think of nostalgia as longing for the past. Homer suggests something deeper. We long not simply for what has been, but for the life that feels most truly our own.
