I want to know the answer to the following question:
Who composed Vartikas on the Panini sutras?
All the background I'm provided with is that "Patanjali, who lived three centuries after Pāṇini, wrote the Mahābhāṣya, the "Great Commentary" on the Aṣṭādhyāyī and Vārtikas.". Is that enough to answer the question?
