Brihat Samhita
मृगघटसंस्थे सवितरि गृह्णीयाल् लोहभाण्डधान्यानि । स्थित्वा मासं दद्याल्लाभार्थी द्विगुणं आप्नोति ॥ ४२-११ ॥
If the phenomena should occur when the Sun is in the signs of Makara (Capricornus) and Kuṃbha (Aquarius) the tradesman shall store up iron and other metals, vessels and grains; if he should dispose of them at the end of a month they would fetch double their price.
