Vishakhadatta wrote which two famous works?

Vishakhadatta is credited with the political drama Mudrarakshasa and the fragmentarily preserved Devichandraguptam. This question belongs to the Gupta and post-Gupta phase, a period reconstructed through inscriptions, coins, monuments, literary works, scientific texts and accounts of foreign travellers. A reliable answer must connect the named ruler, author, work, institution, title or event with the correct chronology and source. The Gupta age is often described as a classical or golden age because of important achievements in Sanskrit literature, temple architecture, sculpture, astronomy and mathematics, but the label should not conceal regional diversity or social and political change. Contemporary inscriptions and coins are especially useful for royal genealogy, conquests, offices, titles and religious affiliation.
