But sudûs and sundus denote a garment the colour of which is regularly mentioned as achḍar ‘greenish.’ So, e.g., twice in the Ḳorân (Sûr. XVIII. 30, LXXVI. 21), where the joys and delights of Paradise are described, _green sundus garments_ are promised to the faithful; and similarly in a tradition mentioned by al-Ġazâli[428] we find it said of men who become brethren in God, ‘Their beauty shines like the sun, and they are clothed in _green sundus garments_’ (wa-ʿaleyhim thiâb sundus chuḍr). But this uncertainty of the colour which is associated with the Night is far less prominent than the fluctuation which prevails when the colour of the Day has to be described. In the former case, with a few exceptions based on the impression which a certain peculiar night may have made on the mind of the speaker or poet, black is by far the prevailing colour. Not so with the colour-distinctions of the solar phenomena. Here usage wavers among three colours, which are usually connected with the various stages of the Sun himself: _golden-yellow_, _red_, and _white_. The greatest definiteness is found to exist with reference to the first. It refers mostly to the dawn and sunset. In Aramaic the early morning is ṣafrâ. Etymologically this word is capable of many explanations which justify the above-expounded mythical conceptions of the dawn. It may be explained, as the soundest lexicographers on Semitic ground do explain it,[429] to denote _curled locks of hair_, or _one who springs, leaps_. Both explanations take us back to mythic attributes of the morning-sun; in the second we see the morning-sun springing up to heaven from behind the hills like a bird (ṣippôr). But I believe that the word ṣafrâ is related to aṣfar, a colour-name in Arabic, which, though like all such it has an extremely vague signification, and may even mean _nigredo_, prevailingly indicates a golden-yellow colour. Now while the Aramaic ṣafrâ is exclusively the morning-sun (compare Ἢὼς κροκόπεπλος, Iliad, VIII. 1, and μελάμπεπλος of the night), in Arabic the colour-word in question is prevailingly applied to the evening-sun: ‘Until upon him came the end of the day, and the Sun put on the garment of yellowness’ (ila an atâ ʿaleyhi âchir al-nahâr wa-labisat al-shams ḥullat al-iṣfirâr, Rom. of ʿAntar, VI. 244. 1). Another example, in which the succession of time comes out with still greater clearness, is: ‘They had defeated al-Noʿmân at noon; then they took rest till the Sun put on the garment of yellowness, and towards evening dust appeared before them’ (wa-kânû ḳad sabaḳû al-Noʿmân bi-niṣf al-nahâr wa-achaḏû râḥâ ḥatta labisat al-shams ḥullat al-iṣfirâr wa-ʿind al-masâ ṭalaʿ ʿaleyhim ġobâr, Rom. of ʿAntar, VI. 35. 2). It is remarkable that in Egyptian the setting sun is said to throw out rays of _tahen_—a metal distinguished for its saffron colour, which is frequently contrasted with the colour red.[430] Chabas finds this contrast to constitute a difficulty in the comparison with the setting
