Brihat Samhita
रोगान्करोति परुषः कपिलस्त्ववृष्टिं धूम्रो गवां अशुभकृत्स्फुरणो भयाय । माञ्जिष्ठरागसदृशः क्षुधं आहवांश्च कुर्यादणुश्च पुररोधं अगस्त्यनामा ॥ १२-१९ ॥
If the disc of the star Canopus should present a disagreeable appearance, there will be disease in the land; if yellow, there will be drought; if of the colour of smoke, cows will suffer; if of unsteady light, mankind will be afflicted with fears; if white red, they will suffer from hunger and from starvation; and if of very small disc, the chief towns will be surrounded by the enemy.
