Gupta age - The Classical Age refers to the period when most of North India was reunited under the Gupta Empire (ca. A.D. 320-550). Because of the relative peace, law and order, and extensive cultural achievements during this period, it was described as a "golden age" that crystallized the elements of what is generally known as Hindu culture with all its variety, contradiction, and synthesis. The golden age was confined to the north, and the classical patterns began to spread south only after the Gupta Empire had vanished from the historical scene.
The military exploits of the first three rulers--Chandragupta I (ca. 319-335), Samudragupta (ca. 335-376), and Chandragupta II (ca. 376-415)--brought all of North India under their leadership. From Pataliputra, their capital, they sought to retain political preeminence as much by pragmatism and judicious marriage alliances as by military strength.
Despite their self-conferred titles, their overlordship was threatened and by 500 ultimately ruined by the Hunas (a branch of the White Huns emanating from Central Asia), who were yet another group in the long succession of ethnically and culturally different outsiders drawn into India and then woven into the hybrid Indian fabric.
Under Harsha Vardhana (or Harsha, r. 606-47), North India was reunited briefly, but neither the Gupta Empire nor Harsha controlled a centralized state, and their administrative styles rested on the collaboration of regional and local officials for administering their rule rather than on centrally appointed personnel. The Gupta period marked a watershed of Indian culture: the Guptas performed Vedic sacrifices to legitimize their rule, but they also patronized Buddhism, which continued to provide an alternative to Brahmanical orthodoxy. The most significant achievements of this period, however, were in religion, education, mathematics, art, and Sanskrit literature and drama.
The religion that later developed into modern Hinduism witnessed a crystallization of its components: major sectarian deities, image worship, devotionalism, and the importance of the temple.
Education included grammar, composition, logic, metaphysics, mathematics, medicine, and astronomy. These subjects became highly specialized and reached an advanced level. The Indian numeral system--sometimes erroneously attributed to the Arabs, who took it from India to Europe where it replaced the Roman system--and the decimal system are Indian inventions of this period. Aryabhatta's expositions on astronomy in 499, moreover, gave calculations of the solar year , the shape and movement of astral bodies with remarkable accuracy. In medicine, Charaka and Sushruta wrote about a fully evolved system, resembling those of Hippocrates and Galen in Greece. Although progress in physiology and biology was hindered by religious injunctions against contact with dead bodies, which had discouraged dissection and anatomy, Indian physicians excelled in pharmacopoeia, caesarean section, bone setting, and skin grafting .
