Brihat Samhita
आश्लेषाअर्धाद्दक्षिणं उत्तरं अयनं रवेर् धनिष्ठाअद्यम् । नूनं कदा चिदासीद्येनौक्तं पूर्वशास्त्रेषु ॥ ३-०१ ॥
At one time, the Sun’s southward course commenced on his reaching the middle of Āśleṣā (the ninth constellation) and its northward course on its reaching the beginning of Dhaniṣṭhā (the twenty-third constellation). This must have been the case as we find it so recorded in ancient books.
