ΛΟΙΜΟΣ

LEXARITHMOS 420

Loimos, the scourge of ancient societies, was not merely a disease but a force that reshaped history, exemplified by Thucydides' account of the Plague of Athens. Often associated with divine wrath or famine, loimos embodied devastation and ruin. Its lexarithmos (420) suggests a connection to the completeness of the cycle of life and death, as well as the concept of ordeal.

Definition

According to the Liddell-Scott-Jones Lexicon, λοιμός (ὁ) primarily signifies "pestilence, plague, a deadly disease," a meaning that predominates in ancient Greek literature. The word describes a catastrophic illness that spreads rapidly and causes mass fatalities, such as the plague that afflicted the Achaean army in Homer's "Iliad," sent by Apollo as punishment.

The meaning of λοιμός often extends to "famine" or "hunger," as these two conditions were closely intertwined in antiquity and frequently occurred simultaneously or led to one another. This connection is evident in numerous sources, including the New Testament, where plagues and famines are mentioned as signs of the end times.

Beyond its literal sense, λοιμός is also used metaphorically to denote "destruction, ruin" more generally, or even "moral pestilence, corruption." It can refer to a person considered a "scourge" to society, implying a profoundly negative and destructive influence.

Etymology

λοιμός ← root LOIM- (possibly shared with lim-)
The etymology of the root LOIM- remains uncertain, but it is often linked to the root of λιμός ("famine, starvation"). This potential common origin underscores the ancient perception that plague and famine were often interconnected catastrophes. Some scholars propose an Indo-European root suggesting "exhaustion" or "weakness," which could account for both concepts.

The family of loimos includes words that describe the disease, its effects, and its characteristics. The derivatives cover both the medical and social dimensions of the scourge, while the connection to limos extends the semantic field to encompass any form of destruction that depletes and annihilates.

Main Meanings

  1. Epidemic disease, plague — The primary and most frequent meaning, referring to a deadly, contagious disease affecting a large population. Extensively used by Homer and Thucydides.
  2. Famine, hunger — Often linked or synonymous with plague, denoting a lack of food and its consequences. Appears in conjunction with plague in prophetic texts.
  3. Destruction, ruin — A more general sense of total devastation or calamity, whether natural or man-made.
  4. Moral pestilence, corruption — Metaphorical use to describe something or someone harmful to moral or social order, a "blight" upon society.
  5. Divine punishment — Often perceived as an manifestation of divine wrath or retribution for human sins, as in the "Iliad."
  6. Contagious disease — General reference to any disease that spreads and causes widespread morbidity.

In Ancient Texts

Three characteristic passages highlight the variety of uses and the impact of loimos in ancient literature:

«καὶ τότ' ἀπὸ σφῶν μὲν πρῶτον ἐπῴχετο καὶ κύνας οὐρῆας, αὐτὰρ ἔπειτ' αὐτοῖσι βέλος ἐχεπευκὲς ἐφιεὶς βάλλ'· αἰεὶ δὲ πυραὶ νεκύων καίοντο θαμειαί. ἐννῆμαρ μὲν ἀνὰ στρατὸν ᾤχετο κῆλα θεοῖο, τῇ δεκάτῃ δ' ἀγορήνδε καλέσσατο λαὸν Ἀχιλλεύς·»
And first he assailed the mules and the swift dogs; but then on the men themselves he let fly his piercing shafts, and smote them; and ever did the pyres of the dead burn thick. For nine days ranged the god's shafts through the army, but on the tenth Achilles called the folk to assembly.
Homer, Iliad A 50-54 (description of the plague)
«ὁ δὲ λοιμὸς ἐνέπεσε καὶ μᾶλλον ἔτι ἐς τὴν πόλιν, ὥστε καὶ τοὺς Ἀθηναίους ἀπορεῖν, οἵτινες ἦσαν οἱ πρῶτοι ἄρξαντες τῆς νόσου.»
And the plague fell even more heavily upon the city, so that the Athenians were at a loss as to who had first started the disease.
Thucydides, History of the Peloponnesian War B 47.3
«ἔσονται σεισμοὶ μεγάλοι κατὰ τόπους καὶ λιμοὶ καὶ λοιμοὶ καὶ φόβητρά τε καὶ σημεῖα ἀπ' οὐρανοῦ μεγάλα ἔσται.»
There will be great earthquakes in various places, and famines and plagues, and fearful sights and great signs from heaven.

κοινός
"Common, public." Contrasts with loimos, which, while afflicting the community, often leads to social isolation and the dissolution of common bonds.

δέσποινα
"Mistress, lady." May allude to deities such as Artemis or Hecate, who were associated with both causing and averting diseases, exercising dominion over life and death.
ἀρθμός
"Bond, friendship." Arthmos represents connection and harmony, concepts violently disrupted by loimos, which imposes isolation and fear, destroying social ties.
