ΓΝΩΜΩΝ (gnomon_pyth) — Lexarithmos 1743

Definition

According to the Liddell-Scott-Jones Lexicon, the γνώμων (from γινώσκω, "to know") originally denotes "one who knows or judges," a "knower," or an "inspector." Its primary meaning is linked to the ability to discern and evaluate, making it a "judge" or "interpreter." This anthropocentric usage quickly evolved into more specific, technical applications, always retaining the core sense of "indication" or "measurement."

In geometry, a gnomon is a figure that, when added to a square, forms a larger square. This concept was central to Pythagorean mathematical thought, where it was used to visualize square numbers and the properties of even and odd numbers. Its visual representation as an "L"-shaped figure, enclosing a smaller square, makes it a fundamental tool for understanding growth and proportion.

Beyond geometry, the gnomon was employed as a practical tool: the "carpenter's square" or "set square" for measuring right angles, and the "indicator" on a sundial, whose shadow marks the time. These uses underscore its function as a "guide" or "measure," whether for construction or chronometry. Philosophically, the gnomon metaphorically signifies a "criterion," a "rule," or a "principle" for evaluating truth or correctness.

Etymology

gnomon ← ginōskō ← ΓΝΩ- (Ancient Greek root belonging to the oldest stratum of the language)

The root ΓΝΩ- is one of the oldest and most productive roots in the Greek language, meaning "to know, understand, perceive." From this root, many words related to knowledge, judgment, and recognition are derived. The word γνώμων is formed with the suffix -μων, which often denotes the agent or the instrument that performs the action of the verb. Thus, the gnomon is "one who knows" or "the instrument by which we know/judge."

Numerous cognate words derive from the root ΓΝΩ-. The verb γινώσκω serves as the base, while derivatives such as γνῶσις (the act or result of knowing), γνώμη (judgment or opinion), and the adjective γνωστός (that which is known) highlight various facets of knowledge. Other words like διάγνωσις (discernment, recognition) and ἀγνώμων (one who does not know or recognize, hence ungrateful) demonstrate its broad semantic range.

Word Family

ΓΝΩ- (root of the verb γινώσκω, meaning "to know")

The root ΓΝΩ- constitutes one of the pillars of the Greek lexicon, expressing the act of knowing, perceiving, and judging. From this fundamental root, a rich family of words developed, covering the entire spectrum of the cognitive process, from simple recognition to deep understanding and wise judgment. Its presence in ancient texts indicates its Ancient Greek origin, belonging to the oldest strata of the language. Each member of the family illuminates a different aspect of this central concept.

γινώσκω verb · lex. 1883

The fundamental verb of the ΓΝΩ- root, meaning 'to know, understand, perceive.' It forms the basis for all other words in the family, expressing the action of acquiring knowledge. It appears as early as Homer and is central to all ancient Greek philosophy.

γνῶσις ἡ · noun · lex. 1263

The 'knowledge,' 'understanding,' 'perception.' As a noun, it describes both the act of knowing and its result. An important term in philosophy (e.g., Plato) and theology (e.g., New Testament) for spiritual or profound knowledge.

γνώμη ἡ · noun · lex. 901

The 'opinion,' 'judgment,' 'view,' 'decision.' Derived from the ΓΝΩ- root, it denotes the intellectual act of judging or forming an opinion. Often used in political and ethical contexts (e.g., Thucydides, 'Histories').

γνωστός adjective · lex. 1623

That which is 'known,' 'recognizable,' or 'familiar.' It describes the quality of having knowledge about something or something being an object of knowledge. Widely used throughout all periods of the Greek language.

γνωρίζω verb · lex. 1770

'To make known,' 'to recognize,' 'to become acquainted with.' This verb expresses the active process of making something known or recognizing it. In the classical era, it primarily means 'to recognize' or 'to learn,' and later also 'to know someone.'

διάγνωσις ἡ · noun · lex. 1298

The 'discernment,' 'recognition,' 'diagnosis.' With the prefix διά- (through, across), it emphasizes the process of detailed knowledge or the recognition of a condition, especially in medicine (e.g., Hippocrates).

ἀγνώμων adjective · lex. 1744

That which 'does not know,' 'unrecognizable,' 'ungrateful.' With the privative a-, it expresses the lack of knowledge or recognition, often with the moral meaning of 'ungrateful' (one who does not acknowledge a kindness received). (Plato, 'Laws').

Philosophical Journey

The trajectory of the gnomon is a journey from a concrete tool to an abstract concept, mirroring the evolution of Greek thought.

6th-5th C. BCE

Pythagorean School

The gnomon gains central importance in geometry and arithmetic as the figure that creates squares and explains the properties of numbers.

5th C. BCE

Classical Greek Literature

Appears as a practical tool (carpenter's square, sundial indicator) and metaphorically as a "criterion" or "rule" in historiography and philosophy.

4th C. BCE

Plato and Aristotle

Plato uses it as a "judge" or "knower" in the "Republic," while Aristotle refers to the sundial's indicator and the geometric gnomon in "Meteorologica" and "Physics."

3rd C. BCE

Euclid

In his "Elements," Euclid rigorously defines the geometric gnomon as the figure added to a parallelogram to form a larger parallelogram similar to the original.

1st C. CE

Roman Period

Its use as a sundial indicator and a geometric term continues, with references in authors such as Plutarch and Ptolemy.

Byzantine Era

Continued Use

The word is preserved in technical texts, mathematical treatises, and commentaries on ancient texts, maintaining its multiple meanings.

In Ancient Texts

The gnomon, as both a tool and a concept, has inspired significant passages in ancient literature.

«ἔστι δὲ γνώμων τὸ χωρίον τὸ προστιθέμενον τῷ παραλληλογράμμῳ, ὅταν περὶ τὴν αὐτὴν διάμετρον ᾖ τῷ ἀρχικῷ παραλληλογράμμῳ, καὶ ποιῇ τὸ ὅλον παραλληλόγραμμον ὅμοιον τῷ ἀρχικῷ.»

«A gnomon is the area which is added to a parallelogram, when it is about the same diameter as the original parallelogram, and makes the whole parallelogram similar to the original.»

Euclid, Elements, Book II, Definition 2

«καὶ οὕτω δὴ οἱ μὲν ἄρτιοι ἀριθμοὶ τῷ γνώμονι, οἱ δὲ περιττοὶ τῷ ἀριθμῷ, ὡς ἔφη Πυθαγόρας.»

«And thus the even numbers by the gnomon, and the odd numbers by the number, as Pythagoras said.»

Plutarch, Life of Pythagoras, 16

«ὁ γὰρ γνώμων οὐ μόνον τὸ ὀρθὸν δεικνύει, ἀλλὰ καὶ τὸ μὴ ὀρθόν.»

«For the gnomon not only shows what is right, but also what is not right.»

Aristotle, Nicomachean Ethics, 1137b (paraphrasing the idea of the gnomon as a criterion)
