Brihat Samhita
पर्यन्तेषुअतिबहुलं स्वल्पं मध्ये तमस्तमोन्त्यऽख्ये । सस्यानां ईतिभयं भयं अस्मिंस्तस्कराणां च ॥ ५-५२ ॥
If all round the disc, the darkness be thick and in the middle, it be slight, the eclipse is technically known as Antyātma (terminally dark): the crops will be injured and mankind will suffer from robbers.
