Brihat Samhita
चापं मघोनः कुरुते निशायाम् आखण्डलायां दिशि भूपपीडाम् । याम्यापरौदक्प्रभवं निहन्यात् सेनापतिं नायकमन्त्रिणौ च ॥ ३५-०७ ॥
If at night the rainbow should be seen in the east, kings will suffer; if in the south, the commander-in-chief will die; if in the west, masters will suffer; and if in the north, ministers will suffer.
