Augustus' religious reformations raised the funding and public profile of the Vestals. They were given high-status seating at games and theatres. The emperor Claudius appointed them as priestesses to the cult of the deified Livia, wife of Augustus. They seem to have retained their religious and social distinctions well into the 4th century, after political power within the Empire had shifted to the Christians. When the Christian emperor Gratian refused the office of pontifex maximus, he took steps toward the dissolution of the order. His successor Theodosius I extinguished Vesta's sacred fire and vacated her temple.
Until what time did the Vestal retain their social distinctions?
A: 4th century

Ancient and medieval Hindu texts identify six pramāṇas as correct means of accurate knowledge and truths: pratyakṣa (perception), anumāṇa (inference), upamāṇa (comparison and analogy), arthāpatti (postulation, derivation from circumstances), anupalabdi (non-perception, negative/cognitive proof) and śabda (word, testimony of past or present reliable experts) Each of these are further categorized in terms of conditionality, completeness, confidence and possibility of error, by each school . The various schools vary on how many of these six are valid paths of knowledge. For example, the Cārvāka nāstika philosophy holds that only one (perception) is an epistemically reliable means of knowledge, the Samkhya school holds three are (perception, inference and testimony), while the Mīmāṃsā and Advaita schools hold all six are epistemically useful and reliable means to knowledge.
