ΠΑΡΑΛΛΑΓΗ

LEXARITHMOS 254

The term παραλλαγή, with a lexarithmos of 254, represents a pivotal concept in ancient Greek scientific thought, particularly in astronomy and mathematics. It describes a deviation, alteration, or difference from an established course, position, or state. Its significance extends from simple change to complex astronomical displacement, underscoring the observation and analysis of phenomena.

Definition

“Παραλλαγή” (παραλλαγή, ἡ) is a noun denoting the act of changing, altering, deviating, or differing. It derives from the verb “παραλλάσσω,” which combines the preposition “παρά” (beside, beyond, against) with the verb “ἀλλάσσω” (to change, alter). This compound suggests a change that occurs “παρά” something else—either alongside it, in relation to it, or as a deviation from it.

In classical Greek, the word is employed in various contexts. In architecture, it might refer to a slight deviation from a straight line or standard proportion. In rhetoric, it could signify a shift in argumentation or tactics. However, its most specialized and significant usage developed within the sciences, particularly in astronomy and mathematics.

In astronomy, “παραλλαγή” acquires a technical meaning, describing the apparent displacement of a celestial body when observed from different positions. This phenomenon, known as parallax, was crucial for ancient astronomers such as Hipparchus and Ptolemy in calculating the distances of celestial objects. The word thus highlights the concept of the relativity of observation and the necessity for correcting measurements.

Etymology

παραλλαγή ← παραλλάσσω ← παρά + ἀλλάσσω ← ἀλλ- (root of the verb ἀλλάσσω, meaning "other, different")
The word “παραλλαγή” is formed from the preposition “παρά” and the noun “ἀλλαγή,” which itself derives from the verb “ἀλλάσσω.” The root “ἀλλ-” is an Ancient Greek root associated with the concept of “other” or “different.” The preposition “παρά” adds the idea of deviation, digression, or comparison, thereby creating a compound notion that describes a change in relation to something else.

Cognate words stemming from the same root “ἀλλ-” include the verb “ἀλλάσσω” (to change), the adjective “ἄλλος” (other, different), the noun “ἀλλαγή” (change), as well as compounds like “μεταλλάσσω” (to transform) and “ἀπαλλάσσω” (to release, free). All these words share the common semantic core of otherness or alteration.

Main Meanings

  1. Change, alteration — The general sense of modification or transformation.
  2. Deviation, digression — A departure from a normal course, rule, or standard.
  3. Difference, dissimilarity — The state of being distinct or unlike something else.
  4. Astronomical parallax — The apparent displacement of a celestial body due to a change in the observer's position (e.g., Ptolemy, "Almagest").
  5. Architectural variation — A minor alteration or irregularity concerning intended symmetry or straightness.
  6. Rhetorical shift — A change in argumentation or strategy within a discourse.
  7. Biological variation — Differentiation within a species or population.

Word Family

ἀλλ- (root of the verb ἀλλάσσω, meaning "other, different")

The root ἀλλ- is a fundamental Ancient Greek root expressing the concept of otherness, difference, and, by extension, change. From this root, a rich family of words developed, describing alteration, exchange, deviation, and differentiation in various contexts. The meaning of the root is not limited to simple substitution but extends to the idea of transformation, alternation, and opposition, making it central to describing dynamic phenomena in both the natural and social worlds.

ἀλλάσσω verb · lex. 1262
The primary verb from which “παραλλαγή” derives. It signifies the act of changing, modifying, or exchanging. Widely used from Homer to the New Testament, e.g., «οὐκ ἀλλάσσειν ἀρετήν» (Herodotus, “Histories” 7.103).
ἀλλαγή ἡ · noun · lex. 73
The direct derivative of “ἀλλάσσω,” denoting the result or act of change. Often used in philosophical texts for the concept of transformation, e.g., «πᾶσα ἀλλαγὴ φόβος» (Euripides, “Iphigenia in Tauris” 1032).
ἄλλος adjective · lex. 331
The primary form of the root, denoting alterity. From this adjective, many words implying differentiation are derived. A fundamental word throughout ancient literature, e.g., «ἄλλος ἄλλων ἐπιθυμεῖ» (Plato, “Republic” 436b).
παραλλάσσω verb · lex. 1443
The verb from which “παραλλαγή” directly originates. It describes a change that is a deviation or displacement in relation to something else, as in astronomical parallax.
παράλλαξις ἡ · noun · lex. 513
A close cognate of “παραλλαγή,” often used as a technical term in astronomy for the apparent displacement of a celestial body. Ptolemy uses it extensively in the “Almagest”.
ἀλλοίωσις ἡ · noun · lex. 1351
Denotes a qualitative change or transformation. An important term in Aristotle's philosophy for the category of quality, e.g., «ἡ ἀλλοίωσις ἐν τῷ ποιῷ» (Aristotle, “Physics” 226a).
ἐναλλάσσω verb · lex. 782
Implies change in a sequence or exchange between two things. Used in texts describing successive changes or alternations.
ἀλλοδαπός adjective · lex. 345
One who comes from another country or place, emphasizing the concept of otherness and difference.

Philosophical Journey

The concept of “παραλλαγή,” though initially general, acquired particular technical significance in ancient Greek science, shaping the understanding of the cosmos.

5th-4th C. BCE (Classical Period)
General Usage
The word “παραλλαγή” and the verb “παραλλάσσω” are used in general senses of change and deviation in philosophical and rhetorical texts, without yet their specialized scientific meaning.
3rd C. BCE (Hellenistic Period)
Scientific Development
With the development of astronomy in Alexandria, “παραλλαγή” begins to be used to describe parallax, the apparent displacement of celestial bodies. Eratosthenes and Aristarchus likely employed the concept in their calculations.
2nd C. BCE (Hipparchus)
Lunar Distance Calculation
Hipparchus of Rhodes, one of antiquity's greatest astronomers, uses the concept of parallax (παράλλαξις) to calculate the distance of the Moon from the Earth, based on observations of its apparent position from different points.
2nd C. CE (Ptolemy)
Systematization in the "Almagest"
Claudius Ptolemy, in his monumental work “Mathematical Syntaxis” (known as the “Almagest”), systematizes the theory of parallax (παράλλαξις) as a central element of geocentric astronomy, providing detailed tables and calculation methods.
Byzantine Period
Preservation and Commentary
Byzantine commentators and astronomers continue to use and analyze the concepts of “παραλλαγή” and “παράλλαξις,” preserving the legacy of Ptolemy and other ancient scientists.

In Ancient Texts

“Παραλλαγή” as a technical term finds its clearest expression in ancient scientific texts, particularly in astronomy.

«τὸ δὲ τῆς σελήνης παράλλαξιν ἔχειν οὐκ ὀλίγην»
The Moon, however, has no small parallax.
Ptolemy, Mathematical Syntaxis (Almagest) V.11
«Περὶ τῆς παραλλαγῆς τῶν ἄστρων»
Concerning the parallax of the stars.
Proclus, Commentary on the First Book of Euclid's Elements
«καὶ οὐδὲν ἄλλο ἢ παραλλαγὴ γίνεται τῆς ὄψεως»
and nothing else happens but a variation of the sight.
Sextus Empiricus, Against the Mathematicians VII.203
