Howard, Michael C. (2012). Transnationalism in Ancient and Medieval Societies: The Role of Cross-Border Trade and Travel. McFarland. стр. 21. ISBN978-0-7864-9033-2., Quote: "Sanskrit was another important lingua franca in the ancient world that was widely used in South Asia and in the context of Hindu and Buddhist religions in neighboring areas as well. (...) The spread of South Asian cultural influence to Southeast Asia, Central Asia and East Asia meant that Sanskrit was also used in these areas, especially in a religious context and political elites."
Pollock, Sheldon (2006). The Language of the Gods in the World of Men: Sanskrit, Culture, and Power in Premodern India. University of California Press. стр. 14. ISBN978-0-520-24500-6., Quote: "Once Sanskrit emerged from the sacerdotal environment ... it became the sole medium by which ruling elites expressed their power ... Sanskrit probably never functioned as an everyday medium of communication anywhere in the cosmopolis—not in South Asia itself, let alone Southeast Asia ... The work Sanskrit did do ... was directed above all toward articulating a form of ... politics ... as celebration of aesthetic power."
Woodard, Roger D. (2008). The Ancient Languages of Asia and the Americas. Cambridge University Press. стр. 1—2. ISBN978-0-521-68494-1., Quote: "The earliest form of this 'oldest' language, Sanskrit, is the one found in the ancient Brahmanic text called the Rigveda, composed c. 1500 BC. The date makes Sanskrit one of the three earliest of the well-documented languages of the Indo-European family - the other two being Old Hittite and Myceanaean Greek - and, in keeping with its early appearance, Sanskrit has been a cornerstone in the reconstruction of the parent language of the Indo-European family - Proto-Indo-European."
Woolner, Alfred C. (1986). Introduction to Prakrit. Motilal Banarsidass. стр. 3—4. ISBN978-81-208-0189-9., Quote:"If in 'Sanskrit' we include the Vedic language and all dialects of the Old Indian period, then it is true to say that all the Prakrits are derived from Sanskrit. If on the other hand 'Sanskrit' is used more strictly of the Panini-Patanjali language or 'Classical Sanskrit,' then it is untrue to say that any Prakrit is derived from Sanskrit, except that Sauraseni, the Midland Prakrit, is derived from the Old Indian dialect of the Madhyadesa on which Classical Sanskrit was mainly based."

[...] According to the colophon, it was copied in the year 252, which some scholars judge to be of the era established by the Nepalese king Aṃśuvarman (also known as Mānadeva), therefore corresponding to 828 CE." - a Palm Leaf manuscript at the Cambridge University Library in Late Gupta in black ink, MS Add.1049.1
