Brihat Samhita
गुरुर्भृगुश्चापरपूर्वकाष्ठयोः परस्परं सप्तमराशिगौ यदा । तदा प्रजा रुग्भयशोकपीडिता न वारि पश्यन्ति पुरन्दरौज्झितम् ॥ ९-३७ ॥
If Jupiter and Venus should be opposite to, that is, 180° apart from each other and if they should be at the same time due east and west of each other, mankind will suffer from disease, from fears and from sorrow, and there will be no rain.
