ONE SEA, THREE NAMES
How did the northern sea come to be called black?
462 BC → TODAY · one sea, three compasses
Turkish kara means black and, archaically, north — so Kara Deniz is a compass point. Before the Turks, the Greeks turned Axeinos, “inhospitable”, into Euxeinos, “hospitable”.
- KARA
- one word, two senses: black and north

KARA
Four forms, in arrival order:
- AXEINOS inhospitable · Pindar, Pythian 4.263, 462 BC
- EUXEINOS hospitable · Pindar, Nemean 4.49
- KARA DENIZ the northern sea · since the 13th century
- BLACK SEA calqued on Kara Deniz · undated
The first name · Greek
The Unwelcoming
The sea's first written name comes from Persian and means “dark coloured”. Greek ears heard “inhospitable” in it — and remade it as “hospitable”.
*axšaina-
“dark coloured”
The Iranian root behind Axeinos, after Vasmer via Schmitt. Cognate with Avestan axšaēna- and Old Persian axšaina-.
RECONSTRUCTED
Póntos Áxeinos
“the inhospitable sea”
First attested: Pindar, Pythian 4.263, 462 BC. The “inhospitable” sense comes from popular etymology, “in all probability” in the north-shore cities.
ATTESTED
Eúxeinos
“hospitable”
The euphemism that replaces the ill-omened name. First attested: Pindar, Nemean 4.49; then into common use.
ATTESTED
Once, in Euripides (Iphigenia in Tauris, 107), the sea is Póntos Mélas — “may be” a poetic metaphor, not a foreign calque.

The second name · Turkish
The compass
Turkish kara keeps two senses: black and north. The second sense turns Kara Deniz into a sailing direction — and the proof that the north-sense sails is a wind.
What the dictionary says: kara
From Ottoman Turkish kara ← Old Anatolian Turkish qara ← Proto-Turkic *kara (“dark, black”).
- adjective: black, dark
- noun, archaic: north
The wind that proves it
karayel = kara + yel: “a wind blowing from the north-west, usually cold, sometimes of storm strength”. A compound built on kara points north at sea.
The second point: Akdeniz
Akdeniz = ak (“west”) + deniz (“sea”), from Ottoman Turkish Ak Deñiz. The Mediterranean is, in Turkish, the western sea.
The system: four colours, four points
After Schmitt, the steppe peoples paired colours with directions: black for north, red for south, white for west, green or light blue for east. “Black Sea” meant “Northern Sea”.
- Nblack · karanorthKaradeniz — the Black Sea
- Sred · kızılsouth, only inside the systemKızıldeniz — the Red Sea
- Wwhite · akwestAkdeniz — the Mediterranean
- Egreen or light blueeastno colour-sea carries this point
A note: an Anatolian variant (Calvet) reads ak as south. Noted; not adjudicated.
The compass reading is the leading account, though not uncontested.
Why not the Scythians: a people north of the sea cannot call its southern sea “northern” (Schmitt).
Three seas, four points, zero colours.



The third name · the calques
The calques
The modern forms — Kara Deniz, Marea Neagră, Chyornoye more, Black Sea — all descend from a single horizon: the 13th century. Who translated first, and exactly when, stays open.
After Schmitt, the modern names reach back no further than the 13th century. No single document is named here: the horizon stays “13th century (Schmitt)”.
Schmitt again: the old name “seems to have” survived in the Near East until the Turks borrowed and propagated it anew. An attributed continuity, still unproven.

The centrepiece · three dates
First the name. Then the master.
Three dates, three forms of the name, three source tags. This is how we read the row of names — an editorial reading, not a scholarly thesis.

EUXEINOS
The Greek shore gets its colony and its euphemism. Histria.

KARA DENIZ
The Ottoman closure makes Kara Deniz the sea's working name. Cetatea Albă + Kiliia.

The Romanian shore inherits Marea Neagră. Northern Dobruja.

The myths
Four things often said about the sea's name. All four fall.
The sea is called black because its deep water is oxygen-free.
No. The name is a compass point: “The name Black Sea is not derived from the color of the water or from any climatic particulars, as previously had been supposed” (Schmitt). The name predates oceanography by millennia. The deep-water measurements live at their source: The Black Sea, two storeys →
The Scythians named it.
No. The Scythians lived north of it — a northern people cannot call its southern sea “northern” (Schmitt).
Euxeinos was the friendly name all along.
No. The friendly name is the cover-up: the euphemism replaced an ill-omened Axeinos (C08–C09).
“Kızıl” means south.
No. Red is south only inside the colour-compass system; the dictionary gives kızıl no cardinal sense (C05).
