LEXARITHMOS 505

The oneiros, a gateway to the subconscious and the divine, a phenomenon that captivated philosophers, poets, and seers from antiquity. From Homeric prophetic visions to psychoanalytic interpretations, the oneiros stands as a multifaceted symbol of human experience and the quest for meaning. Its lexarithmos (505) hints at its complexity and dual nature.

Definition

According to the Liddell-Scott-Jones Lexicon, ὄνειρος (ὁ) primarily means "a dream, a vision in sleep." The word describes the mental activity experienced during sleep, often taking the form of images, sounds, emotions, or narratives. In ancient Greek thought, the ὄνειρος was not merely a random cerebral function but was frequently regarded as a medium for communication with the divine, a premonition of future events, or a reflection of internal states.

The interpretation of dreams (oneirocritica) was a widespread practice, with specialized dream-interpreters undertaking to decipher the messages hidden behind dream imagery. From Homer, where gods send dreams to mortals, to philosophers like Plato and Aristotle, who attempted to explain their nature in a more rational manner, the ὄνειρος maintained its central position in the understanding of the world and humanity.

In philosophy, the ὄνειρος was often presented as an example of the uncertainty of sensory perception and the necessity of critical thought. The distinction between reality and dream constituted a fundamental question for skeptics and Platonists, who questioned the reliability of the senses. The nature of the dream, as a state between sleep and wakefulness, offered a rich field for metaphysical and epistemological inquiries.

Etymology

ὄνειρος ← of uncertain origin, possibly from Proto-Indo-European *h₁ner- "dream" or *sner- "to twist, turn".
The etymology of ὄνειρος remains a subject of debate. One theory connects it to the Proto-Indo-European root *h₁ner- meaning "dream," with possible cognates in other Indo-European languages. Other proposals link it to roots suggesting "turning" or "twisting," referring to the cyclical nature of sleep and dreams. However, no single etymology has been universally accepted, highlighting the ancient and largely mysterious nature of the word.

Related words include the verb ὀνειροπολέω ("to dream, to see dreams"), ὀνειροπόλος ("dreamer, dream-interpreter"), ὀνειροκρίτης ("dream-interpreter"), and ὀνειροκρισία ("dream interpretation"). Also, the word ὄναρ (τό, "dream," poetic form) is closely associated, often used interchangeably or complementarily.

Philosophical Journey

The concept of the dream has traversed Greek thought from the dawn of literature to philosophical analysis and medical observation.

8th C. BCE
Homer
In the «Iliad» and «Odyssey», dreams are often of divine origin, sent by the gods to warn, guide, or mislead mortals. There is a distinction between 'true' dreams coming through the gate of horn and 'false' ones from the gate of ivory (Odyssey 19.560-567).
5th C. BCE
Presocratics & Tragedians
Presocratics like Heraclitus refer to dreams as a private reality. In tragedies (e.g., Aeschylus, Sophocles), dreams function as omens or as manifestations of internal conflicts and guilt.
4th C. BCE
Plato
In the «Republic» (571c-572b), Plato analyzes dreams as manifestations of the soul's lower, bestial desires that are unleashed during sleep. However, he also acknowledges the possibility of prophetic dreams in pure souls.
4th C. BCE
Aristotle
In his works «On Sleep and Waking», «On Dreams», and «On Prophecy in Sleep», Aristotle offers a more rational, physiological explanation of dreams, attributing them to residual sensory impressions and bodily disturbances, rejecting their divine origin.
2nd C. CE
Artemidorus
Artemidorus Daldianus authors the «Oneirocritica», a five-volume work that constitutes the most complete ancient treatise on dream interpretation, categorizing dreams and offering detailed interpretations of symbols.
3rd-4th C. CE
Neoplatonists
Neoplatonists, such as Plotinus and Proclus, return to the idea of dreams as gateways to the transcendent world, as means for the soul to communicate with higher realities or receive divine revelations.

In Ancient Texts

Ancient Greek literature is replete with references to dreams, highlighting the variety of their interpretations and functions.

«οὐ γάρ τι σίγ᾽ ὄνειρος ἦλθε, φαινόμενος δ᾽ ἔλεξεν.»
For the dream came not silently, but appeared and spoke.
Aeschylus, Prometheus Bound 659
«ἀλλὰ καὶ ἐν τοῖς ὕπνοις ἔνεστιν ὅ τι καὶ τῆς ψυχῆς τὸ θηριῶδες καὶ ἄγριον.»
But even in sleep there is something of the wild and bestial part of the soul.
Plato, Republic 571c
«τὰ μὲν γὰρ ὄνειρα τῶν φαντασμάτων ἐστίν, οὐ τὰ φαντάσματα τῶν ὀνείρων.»
For dreams are phantoms, not phantoms dreams.
Aristotle, On Dreams 459a22
