ΠΛΑΓΙΑΥΛΟΣ (plagiaulos) — Lexarithmos 825 · Etymology, Meanings

Definition

According to the Liddell-Scott-Jones Lexicon, the «πλαγίαυλος» (πλαγίαυλος, ὁ) is defined as "transverse aulos, flute." It is a wind musical instrument that differs from the common aulos (which was played vertically) in that it was held and played in a horizontal or oblique position. Its construction involved a tube with finger holes, into which the musician blew through a side embouchure, producing sounds by covering and uncovering the holes.

The «πλαγίαυλος», though less prevalent than the vertical aulos in classical Greece, held its own distinct place in the musical landscape. Its use is often associated with pastoral scenes and the worship of the god Pan, who is frequently depicted with a similar instrument, the syrinx, although the syrinx is typically vertical and composed of multiple pipes. The «πλαγίαυλος», with its more "natural" and less ritualistic sound, was likely employed in freer and more improvisational musical expressions.

References to the «πλαγίαυλος» in ancient texts are rare, suggesting it did not hold the same central position as the aulos or lyre. However, the very existence of the word and the description of its function attest to the variety of musical instruments and the ingenuity of the ancient Greeks in sound production. Its significance lies in its recognition as an ancestor of the modern transverse flute, bridging ancient and more recent musical traditions.

Etymology

πλαγίαυλος ← πλάγιος + αὐλός (Ancient Greek roots)

The word «πλαγίαυλος» is a compound, derived from two distinct Ancient Greek roots: the adjective «πλάγιος», meaning "oblique, sideways, transverse," and the noun «αὐλός», which refers to any kind of pipe, but primarily to a wind musical instrument, such as a flute or aulos. This compound precisely describes the instrument's fundamental characteristic: a pipe held and played obliquely, in contrast to most ancient auloi which were vertical.

The two constituent roots, «πλάγιος» and «αὐλός», themselves form nuclei of extensive word families in the Greek language. From «πλάγιος» derive words denoting a sideways direction or position, such as the verb «πλαγιάζω» (to lie sideways) and the adverb «πλαγίως» (in a transverse manner). Correspondingly, from «αὐλός» originate terms related to the instrument and the act of playing it, such as the verb «αὐλέω» (to play the aulos) and the nouns «αὐλητής» (aulos player) and «αὐλητρίς» (female aulos player). The «πλαγίαυλος» represents a specific compound that combines the meanings of these two roots to define a particular musical instrument.

Main Meanings

The transverse aulos, the transverse flute — The primary and literal meaning, referring to the musical instrument held and played obliquely.
Musical instrument of pastoral music — Often associated with rural scenes and nature, due to its connection with the god Pan and satyrs.
Symbol of freedom and improvisation — In contrast to the ritualistic aulos, the «πλαγίαυλος» may suggest a more unpretentious and spontaneous musical expression.
Ancestor of the modern flute — In musicological history, it is recognized as the ancient precursor to the modern transverse flute.
Instrument with a sound distinct from the vertical aulos — The oblique blowing method likely imparted a softer or "airy" sound compared to the sharp tone of the traditional aulos.
Rare instrument in Classical Greece — Its limited mention suggests it was not as widespread as other wind or string instruments.

Word Family

PLAG- + AUL- (roots of πλάγιος 'oblique' and αὐλός 'flute')

The word «πλαγίαυλος» serves as a characteristic example of a compound word in Ancient Greek, where two distinct roots, PLAG- (from πλάγιος) and AUL- (from αὐλός), combine to create a new concept. The root PLAG- describes the notion of oblique movement or position, while the root AUL- refers to hollow pipes, primarily musical instruments. The word family presented here highlights both the autonomous developments of these two roots and their combinatorial power in naming specific objects, such as the transverse flute.

Philosophical Journey

The history of the «πλαγίαυλος», though not as rich in written testimonies as other instruments, can be outlined through archaeological findings and rare mentions.

6th-5th C. BCE

Archaic and Classical Period

Probable emergence and use in pastoral settings. While the vertical aulos dominated religious ceremonies and theatrical performances, the «πλαγίαυλος» may have been used in more informal occasions.

3rd C. BCE

Theocritus, Idylls

Theocritus, in his pastoral poetry, refers to musical instruments reminiscent of the «πλαγίαυλος», though he more often describes the syrinx. The atmosphere of his idylls is ideal for the sound of such an instrument.

1st C. BCE

Diodorus Siculus, Historical Library

Diodorus mentions the invention of the aulos by the Egyptians and its evolution, without, however, clearly distinguishing between vertical and transverse types, perhaps suggesting the existence of various variations.

1st-2nd C. CE

Plutarch, On Music

Plutarch, discussing the history and theory of music, refers to various types of auloi and their uses. Although the «πλαγίαυλος» is not a central topic, the mention of a variety of instruments leaves room for its existence.

2nd C. CE

Athenaeus, Deipnosophistae

Athenaeus, in his extensive work on symposia, describes a plethora of musical instruments and their uses. While the «πλαγίαυλος» is not explicitly named, the discussion of wind instruments implies their wide variety.

Modern Musicology

Recognition as ancestor

Recognized as one of the oldest types of transverse flute, with archaeological findings from Greece and Rome confirming its existence, bridging ancient and modern musical traditions.

In Ancient Texts

Although the «πλαγίαυλος» is not frequently mentioned explicitly in classical texts, its presence is implied in descriptions of musical instruments and pastoral scenes.

«καὶ πλάγιοι δὲ αὐλοὶ ἐπινοηθέντες ὕστερον»

and transverse flutes having been invented later

Athenaeus, Deipnosophistae IV, 182f
