Emprunté dès l’an mil pour l’étoile la plus brillante de la constellation, ce qui lui vaut sans doute de figurer sur l’astrolabe, il vient de Ḏanab al-Ğady, « la Queue du Chevreau » (voir Fig. 40a), avant qu’au début du XIXe siècle ce nom ne soit également attribué à γ Cap. C’est en tout cas aujourd’hui le nom proposé par l’UAI. Ar. : 1. Ḏanab al-Ğady, al-Ṣūfī. Lat. Denebaliedi, Llobet, puis Deneb Algedi p/ γ Cap, Stöffler, Bayer. 2. Uluġ Bēg > ‘Danab AlGjedi’, Hyde, Deneb Algedi, Allen, puis Rumrill, Rhoads, Hoffleit, etc., UAI. 2. Ḏanab al-Ğady, Uluġ Bēg > ‘Dsanab el-Dscheddi’, Lach, d’où Deneb el dscheddi, Bode, repris p/ Allen. Scheddi, Widmann-Schütte, Welcher Stern ist das ? (1949), Scheddi, Nit. 01.
AUTRE NOM : Nashira [Post.]. [سعد] ناشرة Sacd Nāšira, « la Propice de Nashira ». Introduit par Pïazzi p/ le couple γδ Cap, cette étoile étant pour lui Nashira Posterior, voir γ Cap. Mais cette appellation s’est progressivement effacée p/ γ Cap au profit de Deneb Algedi, ainsi que le consacre Allen. NB : on trouve ‘al-Muḥibbain’, accus. de المحبّان, al-Muḥibbān, « les Deux amis » (cas sujet / nominatif), p/ γδ Cep, M. A. Sédillot, MémB►, 225, là où, à partir d’al-Qazwīnī, Ideler donne ‘El-muhhibbain’ (cas objet / accusatif) Allen ‘Al-Muḥibbain’, repris p/ Nit. 02.
in English:
Coined as early as the year 1000 to refer to the brightest star in the constellation – which is no doubt why it appears on the astrolabe – the name derives from Ḏanab al-Ğady, ‘the Tail of the Kid’ (see Fig. 40a), before this name was also applied to γ Cap in the early 19th century. In any case, this is the name currently proposed by the IAU. Arabic: 1. Ḏanab al-Ğady, al-Ṣūfī. Latin: Denebaliedi, Llobet, then Deneb Algedi for γ Cap, Stöffler, Bayer. 2. Uluġ Bēg > ‘Danab AlGjedi’, Hyde, Deneb Algedi, Allen, then Rumrill, Rhoads, Hoffleit, etc., UAI. 2. Ḏanab al-Ğady, Uluġ Bēg > ‘Dsanab el-Dscheddi’, Lach, hence Deneb el dscheddi, Bode, adopted by Allen. Scheddi, Widmann-Schütte, Welcher Stern ist das? (1949), Scheddi, Nit. 01.
ALTERNATIVE NAME: Nashira [Posterior]. [سعد] ناشرة Sacd Nāšira, ‘the Auspicious One of Nashira’. Introduced by Pïazzi for the pair γδ Cap, this star being, for him, Nashira Posterior; see γ Cap. However, this name gradually fell out of use for γ Cap in favour of Deneb Algedi, as established by Allen. NB: ‘al-Muḥibbain’ is found, the accusative of المحبّان, al-Muḥibbān, ‘the Two Friends’ (subject / nominative case), for γδ Cep, M. A. Sédillot, MémB►, 225, whereas, following al-Qazwīnī, Ideler gives ‘El-muhhibbain’ (object / accusative case) and Allen ‘Al-Muḥibbain’, as cited in Nit. 02.
