Surya Siddhanta
स्वच्छत्वाद् द्वादशाम्शो +अपि ग्रस्तश् चन्द्रस्य दृश्यते । लिप्तात्रयम् अपि ग्रस्तम् तीक्ष्णत्वान् न विवस्वतः॥
Owing to her clearness, even the twelfth part of the moon, when eclipsed (gmsta), is observable; but, owing to his piercing brilliancy, even three minutes of the sun, when eclipsed, are not observable. [The commentator regards the negative which is expressed in the latter half of this verse as also implied in the former, the meaning being that an obscuration of the moon's disk extending over only the twelfth part of it does not make itself apparent. We have preferred the interpre- tation given above, as being better accordant both with the plain and simple construction of the text and with fact.]
