ΜΕΣΗΜΒΡΙΝΟΣ

LEXARITHMOS 725

The meridian, in ancient Greek thought, was not merely a geographical or astronomical line, but a concept that linked the middle of the day with the direction of the South. From the everyday experience of midday to the complex cartographies of Ptolemy, the meridian served as a fundamental tool for understanding the world and time. Its lexarithmos (725) reflects the precision and measurement required for its application.

Definition

The term «μεσημβρινός» (ὁ) in Ancient Greek primarily refers to that which pertains to midday (μεσημβρία) or to the South. As a noun, it can denote the "meridian line," an imaginary great circle passing through the Earth's poles and a specific point on its surface, or the corresponding circle in the celestial sphere. This concept was central to ancient astronomy and geography for determining geographical coordinates and understanding the movement of celestial bodies.

Beyond its technical usage, the term could also refer to persons, designating a "southerner" or "one who comes from the South." The connection to midday is inextricable, as midday is the moment when the Sun reaches the highest point of its trajectory, i.e., on the observer's meridian circle.

The meaning of the term extends to temporal references, describing anything that occurs or belongs to the midday hour. The precise determination of the meridian was vital for ancient astronomers, such as Hipparchus and Ptolemy, as it allowed for the measurement of geographical latitude and the construction of accurate maps.

Overall, the meridian embodies the ancient Greeks' endeavor to systematize their understanding of space and time, connecting celestial observation with the practicalities of geography and navigation.

Etymology

μεσημβρινός ← μεσημβρία ← μέσος + ἡμέρα
The word «μεσημβρινός» derives from the noun «μεσημβρία», which is a compound of «μέσος» (meaning "middle, in between") and «ἡμέρα» (meaning "day"). This compound literally describes the "middle of the day." The root «μεσ-» and the root «ἡμερ-» are Ancient Greek roots belonging to the oldest stratum of the language, without external references.

The family of «μεσημβρινός» highlights the connection between "middle" and "day." From the root «μεσ-» arise words such as «μεσότης» (the middle state, moderation) and «μεσάζω» (to be in the middle). From the root «ἡμερ-» we have words like «ἐφήμερος» (lasting for one day) and «διημερεύω» (to spend the day). The compound «μεσημβρία» and its derivatives, such as «μεσημβρινός», represent the culmination of this conceptual encounter.

Main Meanings

  1. Astronomical Circle — The imaginary great circle passing through the celestial poles and the zenith of an observer, on which the Sun reaches its highest point at midday.
  2. Geographical Line — The imaginary circle on the Earth's surface passing through the geographical poles and a specific point, defining longitude.
  3. Pertaining to Midday — Anything concerning the midday hour, e.g., «μεσημβρινὸς ὕπνος» (midday nap).
  4. Southern, Pertaining to the South — As an adjective or noun, that which is located in the South or originates from the South. E.g., «μεσημβρινοὶ ἄνεμοι» (southern winds).
  5. Inhabitant of the South — As a noun, a person residing in southern regions.
  6. Culminating Point — Metaphorically, the highest or peak point of a course or state, just as midday is the highest point of the day.

Word Family

mes- / hemer- (roots of μέσος and ἡμέρα)

The family of «μεσημβρινός» emerges from the compounding of two fundamental Ancient Greek roots: the root «μεσ-», which denotes "middle" or "intermediate," and the root «ἡμερ-", which refers to "day." This conjunction creates a semantic field extending from the simple temporal concept of midday to the complex geographical and astronomical lines that divide and organize the world. Each member of the family illuminates a different aspect of this composite relationship, either as an independent concept or as a derivative of the original compound.

μέσος adjective · lex. 515
Meaning "that which is in the middle, intermediate." It is one of the two primary components of «μεσημβρινός», highlighting the central position of the Sun at midday or the intermediate nature of a line.
ἡμέρα ἡ · noun · lex. 154
Meaning "day." It is the second primary component of «μεσημβρινός», referring to the temporal duration and, specifically, to the midday hour.
μεσημβρία ἡ · noun · lex. 406
«μεσημβρία» is the "midday hour" or the "southern direction." It forms the direct basis for «μεσημβρινός», connecting the middle of the day with the direction of the South, where the Sun is at its highest point.
μεσημβρίζω verb · lex. 1212
Meaning "to take a midday nap, to rest at midday" or "to go south." It shows the practical, everyday application of the concept of midday and the southern direction.
μεσότης ἡ · noun · lex. 823
«μεσότης» means "the middle state, moderation." Derived from «μέσος», it highlights the philosophical dimension of the "golden mean" as a virtue, as seen in Aristotle.
ἐφήμερος adjective · lex. 928
Meaning "lasting for one day, ephemeral." Derived from «ἡμέρα», it underscores the transience of time, in contrast to the stability of meridian lines.
διημερεύω verb · lex. 1372
Meaning "to spend the day, to last all day." It reinforces the concept of temporal duration associated with «ἡμέρα».
μεσημβρινός adjective · lex. 725
The adjective «μεσημβρινός» means "pertaining to midday" or "southern." It is the adjectival form of the entry's headword, describing characteristics associated with the meridian circle or the southern direction.

Philosophical Journey

The concept of the meridian, from simple solar observation to its scientific codification, spans ancient Greek thought.

8th-6th C. BCE (Archaic Period)
Early References
«ἡμέρα» and «μέσος» are fundamental concepts. «μεσημβρία» primarily refers to the midday hour, often associated with rest or intense heat.
5th-4th C. BCE (Classical Period)
Geographical and Meteorological Use
Herodotus and Thucydides use «μεσημβρία» for the South. Aristotle, in his *Meteorology*, analyzes meridional winds and their relation to seasons.
3rd C. BCE (Hellenistic Period)
Geodetic Application
Eratosthenes employs meridians for calculating the Earth's circumference, marking their scientific application in geodesy.

Astronomical Development
Hipparchus further develops astronomy and geography, using meridians for precise mapping and the determination of geographical coordinates.
2nd C. CE (Roman Period)
Ptolemaic Codification
Claudius Ptolemy, in his *Almagest* and *Geography*, codifies the use of meridians as fundamental axes for celestial and terrestrial mapping, making them foundational for his science.
Byzantine Period
Continuation of Tradition
Ptolemaic geography and astronomy continue to be taught, with «μεσημβρινός» retaining its technical significance in scientific texts and commentaries.

In Ancient Texts

The significance of the meridian in ancient science and literature is highlighted in texts such as:

«ὁ δὲ μεσημβρινὸς κύκλος, δι' οὗ ὁ ἥλιος φέρεται, διὰ τῶν πόλων τοῦ κόσμου καὶ τοῦ ζενίθ τοῦ τόπου διέρχεται.»
“The meridian circle, through which the sun moves, passes through the poles of the world and the zenith of the place.”

«τὰ δὲ πρὸς μεσημβρίαν μέρη τῆς οἰκουμένης διὰ τὴν τοῦ ἡλίου θερμότητα ἀοίκητα.»
“The parts of the inhabited world towards the south are uninhabitable due to the heat of the sun.”

«οἱ δὲ μεσημβρινοὶ ἄνεμοι θερμότεροι καὶ ὑγρότεροι τῶν βορείων.»
“The southern winds are hotter and more humid than the northern ones.”
