ΠΑΝΣΕΛΗΝΟΣ

LEXARITHMOS 694

Panselēnos, the full moon, represents one of the most striking and extensively studied celestial phenomena in antiquity. As a compound word, it combines the concept of "all" (πᾶς) with that of the "moon" (σελήνη), signifying the totality and completeness of the lunar cycle. Its lexarithmos (694) is associated with notions of wholeness and scientific observation.

Definition

In Ancient Greek, panselēnos (a compound word from πᾶς 'all, whole' and σελήνη 'moon') refers to the full phase of the moon, when its entire visible disk is illuminated by the sun. It was a phenomenon of profound scientific, religious, and practical significance. Ancient Greek astronomers, such as Aristarchus and Ptolemy, meticulously studied the moon's movements and phases, using the full moon as a crucial reference point for calculating eclipses and dating events.

Beyond its purely astronomical dimension, the panselēnos also had significant implications for daily life and religious practices. Many religious festivals and rituals were linked to the appearance of the full moon, as its complete light was considered auspicious and sacred. Furthermore, the full moon influenced agricultural work, navigation, and even medicine, with the ancients believing it affected tides and human bodies.

The word appears in a wide range of texts, from scientific treatises and historical works to poetic descriptions, underscoring its central place in ancient Greek thought. The accurate observation and understanding of the full moon were fundamental to the development of astronomy and chronology, making it a cornerstone of scientific knowledge.

Etymology

panselēnos ← pas + selēnē (Ancient Greek compound word)
The word "panselēnos" is a compound derived from two Ancient Greek elements: the adjective "πᾶς, πᾶσα, πᾶν" (meaning "all, whole, every") and the noun "σελήνη" (meaning "moon"). This compound literally describes the "whole moon" or "the moon in its entirety." The root of "πᾶς" is Ancient Greek and denotes completeness, while the root of "σελήνη" is also Ancient Greek and is associated with light and radiance. The word was formed within the Greek language to describe this specific astronomical phenomenon.

The word panselēnos is composed of two distinct roots, pan- (from πᾶς) and selēn- (from σελήνη), which generate rich families of cognate words. From the root pan- derive words denoting totality, universality, or extent, while from the root selēn- derive words related to the moon and its phenomena. The combination of these two roots creates a word with precise and descriptive meaning.

Main Meanings

  1. The full phase of the moon — The astronomical concept of the moon when its entire disk is illuminated by the sun, as observed from Earth.
  2. The time of the full moon — The period during which the full moon occurs, often associated with specific dates in lunar calendars or festivals.
  3. Reference point for eclipses — The full moon as the necessary condition for lunar eclipses to occur, as the Earth is then positioned between the Sun and Moon.
  4. Connection to religious festivals — Many ancient Greek festivals and rituals, such as the Eleusinian Mysteries, were linked to the full moon, considered a sacred period.
  5. Influence on natural phenomena — The belief that the full moon affects tides, vegetation, and even the behavior of animals and humans.
  6. Chronometric unit — The use of the full moon as a means of dating and dividing time, especially in lunar calendars.

Word Family

pan- (from pas) and selēn- (from selēnē)

The root of panselēnos is composite, derived from two powerful Ancient Greek roots: "pan-" (from πᾶς, πᾶσα, πᾶν) denoting totality and universality, and "selēn-" (from σελήνη) referring to the moon and its light. These two roots, each with its own rich family of words, combine to form the concept of the "entire moon." The resulting word family covers a wide range of concepts, from universality and completeness to the phenomena and properties of the moon.

Plutarch
Plutarch, in his work "On the Face in the Moon's Orb," examines the nature of the moon and the full moon from both a philosophical and scientific perspective.

In Ancient Texts

Three characteristic passages from ancient literature referring to the full moon:
