The Kolobi (also rendered Colobi) were an ancient people of northeastern Africa mentioned in both PtolemyâÂÂs Geography and StraboâÂÂs Geographica. Although classical sources provide only brief descriptions, both authors place the Kolobi near the Red Sea coast, and likely refer to the same group. Their name and position in ancient geographical texts suggest they were one of the coastal or near-coastal populations known to Greco-Roman writers navigating the African shorelines of the Red Sea.
The earliest reference to the Kolobi appears in Geographica by Strabo (1st century AD), who names a âÂÂGrove of the Colobiâ along the Red Sea route south of Egypt:
The term kolobi (Greek: úÿûÿòÿï) may be derived from kolobos (úÿûÿòÃÂÃÂ), meaning âÂÂmutilatedâ or âÂÂcut short.â This suggests that the Kolobi were known for bodily ritual practices, such as circumcision, castration, or asceticism, though no specific cultural practices are recorded. The mention of a grove suggests a ritual or cultic site, perhaps recognized by Red Sea travelers.
A century later, Claudius Ptolemy (2nd century AD) listed the Kolobi in Geography 4.7.21, as part of a geographic sequence of peoples from north to south in northeast Africa:
PtolemyâÂÂs sequence positions the Kolobi in the northern Red Sea corridor, possibly near modern-day Eritrea or eastern Sudan, and notably north of the Axoumitai (Axumites). This geographic correspondence with StraboâÂÂs âÂÂColobiâ further supports their identification as the same people.
In both accounts, the Kolobi are placed in the coastal or subcoastal regions of the western Red Sea, near known ancient ports and waystations used by Roman and pre-Roman maritime traffic.
Later in the same chapter (çç4.7.23âÂÂ25), Ptolemy describes the sources of the Nile, including Lake Koloe, and interior cities such as Auxoume (Axum) and Koloe city. These southern inland regions lie significantly further south than the Kolobi. While the similarity between the names Kolobi and Koloe attracts attention, there is no clear evidence of a direct connection, and it is possible that the resemblance is merely linguistic.
