ΑΡΤΗΡΙΑ (arthria) — Lexarithmos 520 · Etymology, Meanings

Definition

According to the Liddell-Scott-Jones Lexicon, ἀρτηρία originally meant 'the windpipe, the respiratory artery, the air-duct.' This was its predominant meaning in classical Greek literature, from Homer to early medical writers like Hippocrates. The word denoted a conduit carrying air, reflecting the observation that arteries appeared empty of air post-mortem.

This misconception arose because arteries, due to their elasticity, contract after death, pushing blood into the veins and heart, thus appearing empty upon dissection. Consequently, ancient Greek physicians, such as Praxagoras of Cos, believed they transported 'pneuma' (air or vital spirit) rather than blood, in contrast to veins (φλέψ) which were clearly filled with blood.

The definitive correction of this anatomical misunderstanding came with Galen in the 2nd century CE, who, through experimental dissection, conclusively demonstrated that arteries contain blood, not air. From then on, the meaning of the word definitively shifted to 'a vessel that carries blood from the heart to the periphery of the body.'

In modern medical terminology, ἀρτηρία retains the meaning of a vessel that carries oxygenated blood from the heart to the tissues, with the exception of the pulmonary artery which carries deoxygenated blood to the lungs. Metaphorically, it can refer to a 'main conduit' or 'vital pathway,' such as the 'artery' of a city.

Etymology

ἀρτηρία ← ἀρτήρ ← root ἀρτ- (from the verb ἀείρω 'to lift, suspend')

The etymology of ἀρτηρία is linked to the root ἀρτ-, which derives from the verb ἀείρω, meaning 'to lift, suspend, hang up.' This connection suggests the idea of an organ that is 'suspended' or 'hung' within the body. The trachea, as an air-duct, is visibly suspended in the neck, while arteries, as a network of vessels, are also 'suspended' and distributed throughout the body. The initial meaning of 'air-duct' was likely reinforced by the perception that air is 'lifted' and 'transported' through these pathways.

Cognate words include ἀρτήρ ('suspender, lifter, windpipe, artery'), which is considered the direct source of ἀρτηρία. Also, derivatives such as ἀρτηριακός ('of or pertaining to the artery or windpipe'), ἀρτηριώδης ('artery-like, windpipe-like'), and medical terms like ἀρτηριοτομία ('incision of an artery or windpipe'), ἀρτηριάζω ('to suffer from arterial disease'), and ἀρτηρίασις ('arterial disease'). All these words retain the basic concept of a conduit or something related to it.

Main Meanings

Windpipe, trachea — The primary meaning in classical Greek, referring to the tube that carries air to the lungs. (e.g., Homer, Iliad)
Vessel carrying air (misconception) — The initial belief of ancient physicians that arteries carried air or 'pneuma' rather than blood, due to their appearance as empty post-mortem. (e.g., Praxagoras)
Vessel carrying blood (anatomical accuracy) — The meaning established by Galen, referring to the vessels that carry blood from the heart to the tissues. (e.g., Galen, 'On the Usefulness of the Parts of the Body')
Main conduit, vital pathway — Metaphorical use for an important road, channel, or means of transport, such as the 'arteries' of a city.
Significant source or flow — In a broader metaphorical sense, something that constitutes a vital source or continuous flow for something else.
A vein (rare, erroneous usage) — In some texts, rarely and erroneously, the word might be used to denote a vein, due to the general concept of a vessel.

Word Family

ἀρτ- (root of the verb ἀείρω, meaning 'to lift, suspend')

The root ἀρτ- derives from the verb ἀείρω, meaning 'to lift, suspend, hang up.' This fundamental concept of suspension or elevation forms the core of this word family, as it describes something that is in an elevated position or is hung. In the case of ἀρτηρία, the initial connection was to the trachea, which is suspended in the neck and carries 'lifted' air. Later, the concept extended to the blood vessels that traverse and are 'suspended' throughout the body, carrying vital substances. Each member of the family develops this initial idea of a conduit or a suspended element.

Philosophical Journey

The history of the word ἀρτηρία is inextricably linked to the evolution of anatomical knowledge and the understanding of the human body in antiquity.

8th-7th C. BCE

Homeric Era

In the Homeric epics, ἀρτηρία refers to the windpipe, the air-duct, without clear anatomical distinction from other vessels. Its use is primarily descriptive.

5th-4th C. BCE

Hippocratic Medicine

Physicians of the Hippocratic school primarily use ἀρτηρία for the trachea. There is confusion with veins, and the belief that arteries carry air or 'pneuma' is widespread.

4th C. BCE

Aristotle and Praxagoras

Aristotle distinguishes between veins and arteries but still believes arteries contain air. Praxagoras of Cos is the first to recognize the pulse of arteries, but he too maintains they carry pneuma.

3rd C. BCE

Herophilus and Erasistratus

In Alexandria, Herophilus and Erasistratus conduct dissections and experiments. Erasistratus begins to suspect that arteries contain blood, but the 'pneuma' theory remains strong.

2nd C. CE

Galen

Galen, through extensive dissections and vivisections, definitively proves that arteries carry blood and not air. His work establishes the modern anatomical understanding for centuries.

Byzantine Era and Beyond

Consolidation of Terminology

Galen's terminology and understanding are adopted and maintained. ἀρτηρία is established as the term for the blood vessel that carries blood from the heart.

In Ancient Texts

The historical evolution of the understanding of ἀρτηρία is reflected in significant ancient medical texts:

«τὸν δὲ πνεύμονα ἀρτηρίαι μὲν καὶ φλέβες καὶ σάρκες καὶ ἀρτηριώδεις φλέβες περιέχουσιν.»

The lung is surrounded by arteries and veins and flesh and arterial veins.

Hippocrates, 'On the Heart' 1

«τὸν μὲν γὰρ ἀέρα διὰ τῆς τραχείας ἀρτηρίας ἀναπνέομεν, τὸ δὲ αἷμα διὰ τῶν φλεβῶν καὶ τῶν ἀρτηριῶν φέρεται.»

For we breathe air through the rough artery [trachea], but blood is carried through the veins and arteries.

Galen, 'On the Usefulness of the Parts of the Body' VI.10

«τὸ δὲ πνεῦμα διὰ τῶν ἀρτηριῶν φέρεται.»

The pneuma is carried through the arteries.

Isopsephic Words (520)

Words from the Liddell-Scott-Jones Lexicon with the same lexarithmos (520) as ἀρτηρία, but different roots, offering interesting semantic connections and contrasts:

ἄδεσμος

ἄδεσμος means 'unbound, unfettered.' In contrast to the artery, which is a vessel 'bound' within the body, this isopsephic word suggests the absence of restriction, perhaps referring to the free flow of blood or air.

ἀνάκλησις

ἀνάκλησις means 'calling back, recall.' It can be linked to the pulse of the artery, which is a continuous 'recall' of life, or to respiration, which is a 'recall' of air.

Ἰλισός

Ἰλισός is the name of a river in Athens. The flow of the river symbolizes the continuous flow of blood in the arteries, a vital pathway traversing the body like a river through the land.

μῖσος

μῖσος means 'hatred.' This isopsephic word offers a strong emotional contrast to the purely biological and vital function of the artery, highlighting the difference between the physical and the psychological.

πόρος

πόρος means 'passage, way, ford.' This word is particularly apt, as an artery is literally a πόρος, a pathway for the transport of blood, confirming its functional significance.

δουλεία

δουλεία means 'slavery, subjugation.' In contrast to the free and uninterrupted flow of life ensured by arteries, δουλεία implies restriction and lack of freedom, offering a strong conceptual antithesis.
