LEXARITHMOS 72

The leech (βδέλλα), a creature often evoking awe and disgust, yet also admiration for its medicinal utility. Since antiquity, the leech (lexarithmos 72) has been synonymous with bloodletting and healing, while metaphorically it became a symbol of insatiable greed. The word, with its ancient Greek root, transports us to the world of ancient medicine, natural history, and moral philosophy.

Definition

According to the Liddell-Scott-Jones Lexicon, βδέλλα (Hirudo medicinalis) is an aquatic worm, known for its ability to attach to living organisms and suck blood. Its presence in ancient Greek literature is extensive, appearing in both natural history texts and medical treatises, where its biology and therapeutic properties are described in detail.

The medical use of the leech, known as bdellism (βδελλισμός), was a common practice in ancient Greece, later adopted and developed by Roman and and Byzantine physicians. It was employed for bloodletting, relieving inflammation, treating edema, and other ailments, based on the prevailing humoral theory of the time. Its ability to absorb blood painlessly, thanks to the anticoagulant substances it secretes, made it a valuable tool.

Beyond its literal meaning, βδέλλα acquired strong metaphorical dimensions. It became a symbol of greed, insatiable desire, and exploitation, characterizing individuals or situations that drain others. This metaphorical usage is evident as early as the Old Testament, in the Book of Proverbs, where the leech is depicted with two daughters crying "Give! Give!", signifying endless demand.

In rare instances, the word βδέλλα was also used to describe other species, such as a specific plant (Theophrastus) or a type of fish (Aristotle), possibly indicating some morphological or functional similarity to the animal species, or simply an extension of the name to less familiar kinds. The dominant meaning, however, always remained that of the blood-sucking worm.

Etymology

βδέλλα ← βδελ- / βδελλ- (Ancient Greek root belonging to the oldest stratum of the language)
The word βδέλλα belongs to an ancient Greek lexical stratum; its internal etymology is not fully transparent, but the root βδελ- / βδελλ- is purely Greek. Its structure suggests a primary onomatopoeic formation, possibly mimicking the sound or sensation caused by the animal, or referring to the act of attachment and suction. Its presence in such early texts underscores its antiquity in the Greek language.

From the same root βδελ- / βδελλ- derive a few but directly related words. The verb βδελλίζω describes the action of the leech, meaning "to suck blood like a leech." The diminutive βδελλίον refers to a "small leech," while the adjective βδελλώδης characterizes something "leech-like" or "resembling a leech," often with a negative connotation. These words constitute the immediate family of βδέλλα, highlighting the animal's basic properties and actions.

Main Meanings

  1. The animal leech — The aquatic worm that sucks blood (Hirudo medicinalis). Mentioned by Aristotle and Theophrastus.
  2. Medical instrument — The use of leeches for therapeutic bloodletting (bdellism) in ancient medicine.
  3. Metaphorically, a greedy person — An individual or entity that drains, exploits, and is never satisfied.
  4. Symbol of insatiable desire — As in Proverbs 30:15, where the leech incessantly demands.
  5. Type of plant — Rare usage by Theophrastus for a specific plant.
  6. Type of fish — Rare usage by Aristotle for a specific type of fish.

Beyond its medical applications, the leech has inspired literary references, particularly regarding its insatiable nature.

«Τῇ βδέλλῃ τρεῖς θυγατέρες ἦσαν ἀγαπῶσαι ἀγαπητῶς, καὶ αὗται οὐκ ἐνεπίμπλαντο τρεῖς, καὶ τετάρτη οὐκ ἤρκεσεν εἰπεῖν ἱκανόν.»

«Τῶν δὲ ζῴων τῶν ἐν τοῖς ὕδασιν ἔνια μὲν ἄναιμα, ἔνια δ’ ἔναιμα. Τῶν δ’ ἐναίμων ἔνια μὲν ἔχει βδέλλας, ὥσπερ οἱ ἰχθύες.»
“Of the animals in the water, some are bloodless, and some have blood. Of those with blood, some have leeches, like fish.”
