This article is about the asterism Alkhiba in the constellation Corvus. For the similarly named asterism in the northern sky, see Alkhiba alshamai (Northern Tent). For the star with a similar name, see Alchiba (the Tent).

Alkhiba (Arabic: الخباء, “the small tent”; also transliterated as al‑Ḫibāʾ and referred to as الْخِبَاء اليماني “Southern Tent”) is an asterism of four stars forming a quadrilateral in the constellation Corvus.

Headword

Arabic: الْخِبَاء اليماني
Transliteration: al‑Ḫibāʾ al‑yamānī
Romanization: al-Khibāʾ al-yamānī
IPA: /ʔal.xɪ.baːʔul.ja.maːniː/

Names

The asterism is referred to in historical sources as al-Khibāʾ (Arabic: الخباء, “the Tent”) without a specifier, and as “Southern Tent” (Arabic: الخباء اليماني, al-Khibāʾ al-yamānī). To avoid confusion with the asterism in Hercules also known as al-Khibāʾ and with the star α Crv named Alchiba, this article uses the form “Southern Tent” (Arabic: الخباء اليماني, al-Khibāʾ al-yamānī), following Ibn Qutayba.

The asterism is also called عجز الأسد (romanized: ʿajuz al-asad, “the Lion’s Hindquarters”), عرش السماك (romanized: ʿarsh al‑Simāk, literally “the Throne of al‑Simāk”; al‑Simāk is a proper name connected with being high or elevated) in works by Ibn Qutayba, al-Marzūqī, and al-Ṣūfī, while the form الأجمال/الأحمال (romanized: al-Ajmāl/al-Ahmāl, “the camels/the loads on camels”) is reported only by al‑Ṣūfī.

Etymology

al-Khibāʾ (Arabic: الخباء, from the Arabic root خبي) denotes a small tent. Lisān al-ʿArab defines al-Khibāʾ as:

الخِباءُ مِنَ الأَبنية: وَاحِدُ الأَخْبية، وَهُوَ مَا كَانَ مِنْ وَبَر أَو صُوفٍ وَلَا يَكُونُ مِنْ شَعَر، وَهُوَ عَلَى عَمُودَيْنِ أَو ثَلَاثَةٍ، وَمَا فوقَ ذَلِكَ فَهُوَ بَيْت.

Al-Khibāʾ (الخِبَاء) is a tent made of camel wool or sheep’s wool, never of goat hair. It usually stands on two or three poles; anything larger than that is called a bayt (large tent).

Concordance

al-Khibāʾ al-yamānī is an asterism of the quadrilateral γ, ε, β, δ Crv in the constellation Corvus, corresponding to the brightest stars 2^nd, 4^th, 5^th, and 7^th of the 7 star Ptolemaic Corvus.

History

Three primary sources describe the Arabic Southern Tent (الخِبَاء اليماني, al-Khibāʾ al-yamānī): Ibn Qutayba, al-Marzūqī, and al-Ṣūfī. Their accounts largely agree, allowing the stars to be identified with high confidence and clarifying how the Arabs envisioned al-Khibāʾ as a celestial figure.

Ibn Qutayba (d. 276 H / 889)

The complete text describing the Southern Tent (al-Khibāʾ al-yamānī) reads:

Original Arabic

قال ابن كناسة: وربما عدل القمر فنزل بعَجُزِ الأَسَدِ، وهي أربعة كواكب بين يدي السِّمَاكِ الأَعْزَلِ، منحدرة عنه في الجنوب، مربعة على صورة النَّعْشِ، يقال لها: عَرْشَ السِّمَاكِ، وتُسَمَّى: الخِبَاءَ.

English translation

Ibn Kunāsa [d. 207H/822AD] said: "Sometimes the moon deviates and alights at the Hindquarters of the Lion ('Ajuz al-Asad). These are four stars situated before the Unarmed Simāk (al-Simāk al-A'zal), sloping down from it toward the south, squared in the shape of the stars of (Na'sh) [the bowl of the Big Dipper α, β, γ, δ UMa]; they are called the Throne of al-Simāk('Arsh al-Simāk) and are also named the Tent (al-Khibā')."

Ibn Qutayba also named this asterism the Southern tent (Arabic: الخباء اليماني، al-Khibāʾ alyamānī) in his description of the Northern Tent. The complete text reads:

Original Arabic

وأولاد الظباء كواكب صغار، فيما بين الظباء والنفزات، وعن يمين نفزات الظباء كواكب مستديرة غير متقارنة، تسمّى: الحوض. والخباء أسفل من الحوض، كواكب في مثل هيئة الخباء اليمانية.

English translation

The fawns, awlād al-Zibāʾ (أَوْلادُ الظِّبَاءِ), are small stars located between al-Zibāʾ (الظِّبَاءِ) and the Gazelle Leaps (النَّفَزَاتِ). To the right of the Gazelle Leaps (نَفَزَاتِ الظِّبَاءِ), there are round, non-aligned stars called al-Hawd (الحَوْضَ, "the Pool"). Below al-Hawd lies al-Khibāʾ (الخِبَاءُ, "the Tent"), a group of stars shaped like the Southern tent (الخِبَاءِ اليَمَانِيَّةِ, al-Khibāʾ alyamāniyah).

Al-Ṣūfī (d. 376 H / 986)

The complete text describing the Southern Tent (al-Khibāʾ al-yamānī) reads:

Original Arabic

والعرب تُسَمِّي هذه الكواكب: عَجُزَ الأَسَدِ، وتزعم أن القمر ربما قصر فنزل بعجز الأسد، وتسمّيها أيضًا: عَرْشَ السِّمَاكِ الأَعْزَلِ، وتسميها أيضًا: الأَجْمَالَ، وتسميها أيضًا: الخِبَاءَ.

English translation

The Arabs call these stars [the seven stars of Ptolemaic Corvus]: the Hindquarters of the Lion (‘Ajuz al-Asad). They claim that the moon sometimes falls short and alights at the Hindquarters of the Lion. They also call them: the Throne of the Unarmed Simāk (‘Arsh al-Simāk al-A‘zal); they also call them: the Camels (al-Ajmāl); and they also call them: the Tent (al-Khibā’).

The name al-Ahmāl (Arabic الأحمال, “the Camel Loads”) appears in some manuscripts, but it seems to be a scribal error. The two forms الأجمال and الأحمال are graphically similar and differ by only a single dot, while al-Ajmal (“the Camels”) is preferable because it lies in the same area as the Arabian constellations al-Sharāsīf (Arabic الشراسيف, “the Tied Camels”) = Hydra and al-Maʿlaf (Arabic المَعْلَف, “the Camels’ feeding trough”) = Crater.

Al-Marzūqī (d. 421 H / 1030)

The complete text describing the Northern Tent (al-Ḫibāʾ ash-Šāmī) on the authority of Ibn al-Aʿrabī (d. 230 H / 845) reads:

Original Arabic

"وقال [ابن الأعرابي]: فيما بين الفَرْدِ وبين زُبَانَى العَقْرَبِ الخِبَاءُ. قال أبو حنيفة: إن كان عنى بالخِبَاءِ عَرْشَ السِّمَاكِ، فذاك، وإلَّا فليس هناك خباء غيره، وقال: على أثر الخِبَاءِ كواكب يقال لها: الشَّرَاسِيفُ، وهي كواكب مستطيلة مثل الحبل. وقال: بين الشَّرَاسِيفِ والخِبَاءِ كواكبُ مستديرةٌ متبدّدةٌ على غير نظام يقال لها: المَعْلَفُ."

English translation

“[Ibn al-Aʿrabī] (d. 230 H / 845) said: Between al‑Fard (Alphard α Hya) and al-Zubānā (α2, β Lib, the claws of the Scorpion) is al‑Khibāʾ. Abū Ḥanīfa (d. 282 H / ~895) said: If by al‑Khibāʾ he meant the throne of al‑Simāk, then that is correct; otherwise, there is no other Khibāʾ there. And he said: Following al‑Khibāʾ are stars that are called al-Sharāsīf (Arabic الشراسيف, the Tied camels); they are elongated stars like a rope [stars of Hydra]. And he said: Between al‑Sharāsīf and al‑Khibāʾ are round, scattered stars, without order, that are called al‑Maʿlaf (Arabic المَعْلَف, the Camels feeding trough) [stars of the constellation Crater].”
