  • Sculptures of Gupta Period

    The Gupta period saw the mighty upsurge of national art. This period is popularly known as the Golden Age in the history of India. The famous Gupta emperors were Samudra Gupta who ruled in 325-375 CE, Chandragupta Vikramaditya 376 -413 CE, and Kumara Gupta 413 - 455 CE. Indian literature, religion, art and literature attained the great height of their glory. The Gupta art and culture not only spread to every nook and corner of India but also reached the Himalayan region and Central Asia. This cultural phase extended towards the south-east across the ocean into the islands of Indonesia or what was known at that time as Dvipantara. This cultural development was due to economic prosperity. This had a direct relation on the spirituality, which India had not seen before.
