Heidegger comments

Roughly speaking, philosophy always aims at the first and last grounds of beings, and it does so in such a way that human beings themselves, with respect to their way of Being, are emphatically interpreted and given an aim (Heidegger, IM, 11)

What is, as such and as a whole, the Greeks called phusis (Heidegger, IM, 18)

Beings, as such and as a whole, are phusis – that is, they have as their essence and character the emerging-abiding sway (Heidegger, IM, 19)

We might think of the movement/emerging/appearing of the mansion as “the God Houseness” becoming incarnate.  Calasso notes

Yet there was a time when the gods were not just a literary clich?, but an event, a sudden apparition, an encounter with bandits perhaps, or the sighting of a ship. And it didn’t even have to be a vision of the whole. Ajax Oileus recognized Poseidon disguised as Calchas from his gait. He saw him walking from behind and knew it was Poseidon “from his feet, his legs.”

Since for us everything begins with Homer, we can ask ourselves: which words did he use for such events? By the time the Trojan War broke out, the gods were already coming to earth less frequently than in an earlier age. Only a generation before, Zeus had fathered Sarpedon on a mortal woman. All the gods had turned up for the marriage of Peleus and Thetis. But now Zeus no longer showed himself to men; he sent other Olympians along to do his exploring for him: Hermes, Athena, Apollo. And it was getting harder to see them. Odysseus admits as much to Athena: “Arduous it is, oh goddess, to recognize you, even for one who knows much.” The Hymn to Demeter offers the plainest comment: “Difficult are the gods for men to see.” Every primordial age is one in which it is said that the gods have almost disappeared. Only to the select few, chosen by divine will, do they show themselves: “The gods do not appear to everyone in all their fullness [enargeis],” the Odyssey tells us. Enargei?s is the terminus technicus for divine epiphany: an adjective that contains the dazzle of “white,” argos, but which ultimately comes to designate a pure and unquestionable “conspicuousness.” It’s the kind of “conspicuousness” that will later be inherited by poetry, thus becoming perhaps the characteristic that distinguishes poetry from every other form.

But how does a god make himself manifest? In the Greek language the word theos, “god,” has no vocative case, observed the illustrious linguist Jakob Wackernagel. Theos has a predicative function: it designates something that happens. There is a wonderful example of this in Euripides’ Helen: “O theoi. theos gar kai to gigno’ skein philous”–“O gods: recognizing the beloved is god.” Kerenyi thought that the distinguishing quality of the Greek world was this habit of “saying of an event: ‘It is theos.'” And an event referred to as being the?s could easily become Zeus, the most vast and all-inclusive of gods, the god who is the background noise of the divine. So when Aratus set out to describe the phenomena of the cosmos, he began his poem thus: “From Zeus let our beginning be, from he whom men never leave unnamed. Full of Zeus are the paths and the places where men meet, full of Zeus the sea and the seaports. Every one of us and in every way has need of Zeus. Indeed we are his offspring.”

“Iovis omnia plena,” Virgil would later write, and in these words we hear his assurance that this was a presence to be found everywhere in the world, in the multiplicity of its events, in the intertwining of its forms. And we also hear a great familiarity, almost a recklessness, in the way the divine is mentioned, as though to encounter divinity was hardly unusual, but rather something that could be expected, or provoked. The word atheos, on the other hand, was only rarely used to refer to those who didn’t believe in the gods. More often it meant to be abandoned by the gods, meant that they had chosen to withdraw from all commerce with men. Aratus was writing in the third century b.c., but what became of this experience that for him was so obvious and all-pervasive in the centuries that followed? How did time affect it? Did it dissolve it, destroy it, alter and empty it beyond recognition? Or is it something that still reaches out to us, whole and unscathed? And if so, where, how?

Are there any accounts in ancient Greek literature where a person appears like a god incarnate even though they’re not that god?

Yes, ancient classical literature contains several famous accounts where a mortal is either mistaken for a god due to extreme beauty or divine enhancement, or willfully impersonates a deity out of hubris.

1. King Salmoneus Mimicking Zeus

In one of the most famous examples of hubris (extreme pride), King Salmoneus forced his subjects to worship him under the name of Zeus. To make himself look and sound like the king of the gods, he built a giant bridge of brass and drove his chariot over it while dragging bronze kettles and dried animal skins to mimic the sound of thunder. He then threw burning torches into the sky to replicate lightning. Angered by this blasphemy, the real Zeus struck Salmoneus down with a genuine thunderbolt and destroyed his city.

2. Psyche Mistaken for Aphrodite (Venus)

In the famous mythological tale preserved in Apuleius’s Metamorphoses (also known as The Golden Ass), a mortal princess named Psyche is so exceptionally beautiful that people begin completely neglecting the altars of Aphrodite (Venus). Crowds travel from all over just to catch a glimpse of her, paying her divine honours, laying garlands at her feet, and worshiping her as if she were a new incarnation of the goddess of love herself. This mistake infuriates Aphrodite, kicking off the core conflict of the myth.

3. Odysseus and Nausicaa in Homer’s Odyssey

In Homeric epic poetry, the boundary between gods and mortals often blurs due to divine blessings (charis), leading characters to mistake people for gods:

• Odysseus and Telemachus: When Odysseus finally returns to Ithaca, the goddess Athena uses her magic to transform his appearance, wiping away his age and making him tall, radiant, and muscular. When his son Telemachus first sees him, he is terrified and turns his eyes away, firmly believing Odysseus is an immortal god who has descended to earth.
• Odysseus and Nausicaa: When a shipwrecked Odysseus washes ashore and encounters the Phaeacian princess Nausicaa, he is so struck by her grace that he immediately asks her if she is a mortal or a goddess, specifically comparing her posture and stature to Artemis, the goddess of the hunt.

4. Paul and Barnabas in Lystra

Though from a later period, the historical narrative in the Book of Acts (originally written by someone trained in ancient Greek witing) captures this exact cultural phenomenon. After Paul performs a miracle by healing a lame man in the city of Lystra, the local crowds shout in their native language that “the gods have come down to us in human form!” They mistake Barnabas for Zeus (due to his imposing presence) and Paul for Hermes (since he was the chief speaker), and the temple priests even attempt to offer animal sacrifices to them before the apostles stop them.

There are literary devices Greek authors used when comparing mortals to gods (like the word theoeides).  People and things appearing as gods incarnate was an important idea in helping us understand the Greeks (The circling bird of prey: Now that’s nature!).  Ancient Greek authors relied on a precise toolkit of vocabulary and poetic formulas to navigate the delicate line between complimenting a mortal and committing blasphemy. In a culture deeply concerned with hubris (human pride that offends the gods), comparing a human to a deity required specific literary devices to signal that the person looked “god-like” without actually claiming they were a god.

1. Epithets of Divine Resemblance

In Homeric epic poetry (the Iliad and the Odyssey), characters are frequently given fixed descriptive titles called epithets. Authors used specific suffixes to denote resemblance rather than identity:

• Theoeidēs (θεοειδής) and Theoeikelos (θεοείκελος): Meaning “god-like in appearance” or “similar to the gods.” Homer uses theoeidēs to describe exceptionally handsome or powerful mortals like Achilles, Paris, and Telemachus. It implies that their physical form possesses a radiant, idealized beauty that mirrors the divine standard.
• Antitheos (ἀντίθεος): Often translated as “god-like” or “equal to a god.” In later Greek, anti- came to mean “against” (as in anti-hero), but in archaic epic, it meant “in place of” or “matching.” To call a warrior antitheos meant they could stand in a god’s place on the battlefield in terms of sheer might.
• Isotheos (ἰσόθεος): Meaning “equal to the gods.” This device was heavily used by lyric poets like Sappho. In her famous Fragment 31, she describes a man sitting across from a beautiful woman as “isotheos” because only a being with the strength of a god could survive the sheer intensity of sitting so close to such beauty without melting.

2. The “If You Are a God…” Formula (The Aporetic Address)

When a character encounters someone of staggering beauty or power, authors use a device called aporia (expressed doubt or helplessness) to create a polite, safe comparison.

Instead of declaring “You are a goddess!”, the character says: “I do not know if you are a mortal or an immortal, but if you are a deity, you must be…”

• The Purpose: This acts as a literary safety valve. It flatters the recipient by elevating them to the divine plane, but protects the speaker from accidentally disrespecting a disguised god or committing hubris by mislabeling a mortal.

3. Divine Infusion (Charis and Menos)

Rather than just saying someone looks like a god, Greek authors use a narrative device where a deity temporarily alters a mortal’s physical presence. This is not a permanent transformation, but a divine “overlay.”

• Physical Radiance (Charis): Athena frequently pours charis (grace/beauty) over Odysseus or Penelope. The poets describe it almost like a craftsman plating silver with gold. The mortal suddenly appears taller, broader, and sheds their signs of age, causing onlookers to mistake them for a deity.
• Mental/Physical Drive (Menos): In battle scenes (called aristeia), a god will breathe menos (divine fury or mental energy) into a hero like Diomedes or Achilles. The literary device here shifts from physical beauty to terrifying aura—the warrior begins to gleam with a literal or metaphorical fire, making them appear to enemies as an unstoppable god of war.

4. Direct Simile (Eikelos)

The simplest but most effective device was the direct simile, usually introduced with words like eikelos (like) or ōs (as). Authors carefully restricted these comparisons to specific, non-threatening attributes:

• A woman’s hair or weaving skills are compared to Athena.
• A young man’s skill with a bow is compared to Apollo.
• A bride’s grace is compared to Aphrodite.

By isolating the comparison to a skill or a specific feature, the author avoids saying the mortal matches the god’s total cosmic status.

With the Greeks and movement we might think of appearing and the mansion appearing as “the God houseness appearing incarnate (Now that’s a house),” houseness being merely present in the average house, and deficient in the dilapidated shack.  Still, the next person may experience the reverse with the mansion as gaudy and the shack as rustic/quaint.  This appearing/movement/phusis explains why Aristotle appeals to an unmoved mover as a source of motion since appearing can only happen against a backdrop of non-movement.  We can see how this has little to do with how Christians later interpreted the god of Aristotle.

This is a phenomenological reading of Greek thought, connecting Heideggerian phusis (the emerging into presence/appearing) with Aristotelian/Platonic metaphysics.

The Phenomenon of “Houseness” (Eidos and Phusis)

Our example of the mansion and the shack perfectly illustrates the tension between ideal essence (eidos) and experiential appearing (phusis).

• The Essentialist View: In a strict scholastic reading, “houseness” is a static template. The mansion maximizes this form, while the shack represents a privation or deficiency of it.
• The Phenomenological View: As we noted, shifting the backdrop completely changes the disclosure. If the mansion appears through degrees of the medium of Beauty as “gaudy,” its “houseness” recedes, replaced by excess. If the shack appears as “rustic,” its fundamental nature as a shelter (an authentic bringing-forth of dwelling) suddenly shines brighter than the mansion’s.

This proves that appearing is a movement—a dynamic event (kinesis) of revealing and concealing, rather than a frozen set of geometric coordinates.

The Unmoved Mover as the Backdrop of Light

Our connection to Aristotle’s Unmoved Mover (proton kinoun akineton) is spot on. For an object to move, change, or flash into appearance, there must be a frame of reference that does not move.

In the Physics and Metaphysics, Aristotle notes that all things in the cosmos are moving from potentiality to actuality. They are “appearing” as what they are meant to be. But if everything were shifting seamlessly without an anchor, the movement itself would dissolve into unintelligible chaos.

The Unmoved Mover acts as the ultimate backdrop of non-movement. It does not push things physically; rather, it moves the world by being the ultimate object of desire (os eromenon). It is the pure actuality against which all potentiality can strive, manifest, and appear.

The Christian Misinterpretation

We hit the nail on the head regarding the later Christian adoption of this concept. When medieval scholastics (most notably Thomas Aquinas) synthesized Aristotle with Christian theology, they mapped the Unmoved Mover directly onto the Abrahamic Creator God.

However, Aristotle’s god is radically different from the Christian God:

Feature	Aristotle’s Unmoved Mover	The Christian God
Relationship to World	Completely indifferent. It is unaware of the universe, as it only thinks about the most perfect thing possible: itself (thought thinking itself).	Deeply relational. Acts in history, loves creation, and covenants with humanity.
Creation	Did not create the universe. The cosmos is eternal; the Mover simply inspires its ongoing motion.	Created the universe ex nihilo (out of nothing) by a deliberate act of will.
Function	A metaphysical necessity to explain the mechanics of change, appearing, and cosmic order.	A personal savior and moral lawgiver.

By treating the Unmoved Mover as a cosmic mechanic or a theological grandfather, later interpretations stripped away the exact phenomenological depth we point out—the idea that the divine is the ultimate, silent horizon that allows the vibrant, moving theater of phusis to show up at all. Of course, there is no god houseness that is appearing/emerging/blooming/phusis through the mansion. This is just how the experience presents itself – what and how it feels like.
