Definition

According to the Liddell-Scott-Jones Lexicon, phakos (φακός, ὁ) primarily refers to the lentil, a pulse that was a staple of the ancient Greek diet. Its cultivation was widespread, providing a significant source of protein, especially for the poorer classes. The word is found in botanical, medical, and culinary texts from the Classical period onwards.

From the characteristic shape of the legume, the word acquired metaphorical meanings. In medicine, it described eruptions or tumors resembling a lentil, as well as the crystalline lens of the eye. This anatomical usage is particularly significant, as it paved the way for the more modern meaning.

The evolution of the word culminates in its adoption to describe the optical lens, i.e., the glass or transparent medium used to refract light in telescopes, microscopes, and eyeglasses. This meaning, though later, is now dominant in Modern Greek, highlighting the language's ability to adapt and describe new technological advancements based on ancient roots.

Etymology

phakos ← PHAK- (Ancient Greek root belonging to the oldest stratum of the language)
The word phakos, and the root PHAK- from which it derives, belongs to the oldest stratum of the Greek language. Its original meaning is directly related to the legume, the lentil, and from its characteristic shape, other meanings later emerged, describing objects of similar form, such as the lens of the eye or the optical lens. Its etymology is not directly connected to other known roots within Greek, suggesting an autonomous linguistic development.

Within Greek, the root PHAK- primarily generates derivatives that describe the legume, its characteristics, or objects with a similar shape. These derivatives are formed either with suffixes (e.g., phakis, phakidion) or through compounds (e.g., phakopoles, phakoeides), always retaining the core meaning related to the shape or substance of the lentil.

Main Meanings

  1. The legume, lentil — The original and most widespread meaning in ancient Greece, referring to the edible pulse (Lens culinaris).
  2. Eruption or tumor in the shape of a lentil — A medical term describing skin lesions or small tumors resembling a lentil.
  3. The crystalline lens of the eye — An anatomical term used by ancient physicians for the transparent organ of the eye.
  4. The optical lens (glass) — The modern meaning referring to a glass or other transparent medium for refracting light (e.g., in telescopes, eyeglasses).
  5. The lentil plant — Botanical usage for the plant from which the legume is derived.
  6. A dish made from lentils — Culinary usage, referring to the meal prepared with lentils.
  7. Something lentil-shaped — General metaphorical usage for objects with a biconvex or flattened spherical shape.

Word Family

PHAK- (Ancient Greek root)

The root PHAK- forms the core of a small but semantically rich family of words in Ancient Greek. Initially associated with the lentil legume, this root extended its semantic field to describe anything with a similar shape – from medical conditions to anatomical parts and, eventually, optical instruments. This evolution demonstrates how the observation of nature led to the creation of new concepts, always maintaining the original visual reference to the shape of the legume.

Philosophical Journey

The word phakos follows an interesting trajectory, from the cuisine and medicine of antiquity to the optical science of the modern era:

5th-4th C. BCE
Classical Greek
Phakos is primarily mentioned as a legume in texts such as Aristophanes' «Acharnians» and Hippocrates, where its nutritional and medicinal properties are described.
4th-3rd C. BCE
Hellenistic Period
Theophrastus, in his «Enquiry into Plants», describes in detail the cultivation and varieties of lentils, establishing the botanical use of the term.
1st C. CE
Roman Period
Dioscorides, in his «De Materia Medica», refers to the therapeutic properties of lentils and their uses in medicine, while the word also begins to be used for the crystalline lens of the eye.
2nd C. CE
Galen
Galen continues the medical tradition, referring to the lentil both as food and as an anatomical component of the eye, contributing to the establishment of this dual meaning.
Byzantine Period
Continued Usage
The word is preserved in medical and culinary texts, as well as in lexicons, maintaining its ancient meanings.
17th C. CE and onwards
Modern Science
With the development of optics, the word is adopted to describe optical devices (glass lenses), due to the similarity in shape with the legume, a meaning that dominates today.

In Ancient Texts

Three characteristic passages from ancient literature that highlight the uses of phakos:

«φακῆς ὀσμὴ»
the smell of lentils
Aristophanes, «Acharnians» 800
«φακὸς δὲ καὶ ὄσπρια πάντα»
lentil and all pulses
Hippocrates, «On Regimen» II.59
«φακὸς ὁ ἥμερος»
the cultivated lentil
Dioscorides, «De Materia Medica» II.105

Isopsephic Words (791)

Words from the Liddell-Scott-Jones Lexicon with the same lexarithmos (791), but different roots, highlighting numerical coincidence:

ἀποβλητικός
Meaning 'fit to be rejected, useless, discardable'. Its numerical connection to phakos might suggest the simplicity of the legume as an everyday food, in contrast to something 'rejectable' or superfluous.
ἀπολιτικός
Meaning 'unpolitical, private, not involved in public affairs'. Its isopsephy with phakos could underscore the neutral, everyday nature of the legume, far from political strife, or the objectivity of the optical lens.
ἰοβαφής
Meaning 'dyed with violet color, purple'. The connection with phakos might be purely coincidental, but could allude to the color of certain lentil varieties or, metaphorically, to the lens's ability to refract light into colors.
κοιλοφθαλμία
Meaning 'hollowness of the eyes'. The isopsephy is interesting, as phakos is directly linked to the eye (crystalline lens). 'Koilophthalmia' could represent the opposite state of healthy vision that the lens enables.
φιλοκόλαξ
Meaning 'one who loves flatterers, fond of flatterers'. The numerical coincidence with phakos can create a contrast between the simplicity and utility of the lentil/lens and the complexity of human relationships characterized by flattery.
