The Arabic Roots of Celestial Terminology
Many prominent stars visible in the night sky today bear names of Arabic origin, a testament to the significant contributions of Islamic astronomers during the Golden Age of Islam. This rich nomenclature reflects a blend of ancient Arabian star lore and translations of classical Greek astronomical texts.
Approximately two-thirds of the commonly used star names in modern astronomy are of Arabic origin. This includes both names derived from indigenous Arabic traditions and those that are Arabic translations or interpretations of Ptolemy’s descriptions.
History and Origin of Arabic Star Names
The history of Arabic star names is multifaceted, stemming from two primary traditions.
Indigenous Arabic Star Lore:
Before the widespread translation of Greek texts, people in the Arabian Peninsula had their own traditional names for stars and asterisms, often associating them with animals, people, or natural phenomena observed in their environment. These names were deeply embedded in their cultural heritage and practical navigation. For instance, the stars we know as Alpha and Beta Ophiuchi were seen as a shepherd and his dog.
Scientific Islamic Arabic Tradition:
A significant influx of Arabic star names came from the translation and study of Claudius Ptolemy’s 2nd-century astronomical treatise, the Almagest. This work, which tabulated 1,025 stars, was translated into Arabic in the 8th and 9th centuries . Muslim astronomers adopted some of Ptolemy’s descriptive phrases, which identified stars by their position within constellations (e.g., “in the right shoulder of The Hunter”), and transformed them into proper names.
A pivotal figure in systematizing and preserving Arabic star names was the 10th-century Persian astronomer Abd al-Rahman al-Sufi (known as Azophi in the West). His Book of Fixed Stars (Kitab suwar al-kawakib al-thamaniya wa-‘l-arba’in), completed around 964 CE, systematically revised Ptolemy’s catalogue, adding his own observations, descriptions, and magnitudes, alongside a listing of Arabic star names. Al-Sufi’s work was groundbreaking as it was the first scientific effort to identify traditional Arabic star names with astronomically located stars .
The transmission of these names to Europe occurred in waves:
First Wave (10th-13th centuries):
Direct borrowings from Arabic star catalogues into European astronomical works, often through translations of astrolabe manuals.
Second Wave (16th-17th centuries):
Introduced by scholars like Johann Bayer, who incorporated popular Arabic names from various sources, including translations of al-Sufi’s work and the Alfonsine Tables, into his Uranometria star atlas (1603).
Third Wave (19th century):
A large number of Arabic-origin names entered European star charts, primarily through the work of astronomers like Giuseppe Piazzi, who relied on earlier translations of Ulugh Beg’s star list
Despite some distortions and misinterpretations during the translation process over centuries, the majority of star names adopted since the Renaissance are Arabic in origin. In 2016, the International Astronomical Union (IAU) officially designated many commonly used Arabic names as proper star names to standardize nomenclature.
