Certain exploration and excavation missions conducted by the Archaeological Department in and around the Keesaragutta temple have brought to light, a number of brick temples, cells and other structures encompassed by brick prakaram along with coins, beads, stucco figures, garbhapatra, pottery, and Brahmi label inscriptions datable to 4th and 5th centuries CE.
On top of one of the rock-cut caves, an early Telugu label inscription reading as ‘Thulachuvanru’ can be noticed.
The 16th-century Venetian explorer Niccolò de' Conti, who visited the Vijayanagara Empire, found that the words in the Telugu language end with vowels, just like those in Italian, and hence referred it as "The Italian of the East"; In the late 19th and the early 20th centuries, the influence of the English language was seen, and modern communication/printing press arose as an effect of the British rule, especially in the areas that were part of the Madras Presidency.
Literature from this time had a mix of classical and modern traditions and included works by such scholars as Gidugu Venkata Ramamoorty, Kandukuri Veeresalingam, Gurazada Apparao, Gidugu Sitapati and Panuganti Lakshminarasimha Rao.
During this period the split of the Telugu from Kannada alphabets took place. The Vijayanagara Empire gained dominance from 1336 to the late 17th century, reaching its peak during the rule of Krishnadevaraya in the 16th century, when Telugu literature experienced what is considered its Golden Age.
A distinct dialect developed in present day Telangana region, due to Persian/Arabic influence: the Delhi Sultanate of the Tughlaq dynasty was established earlier in the northern Deccan Plateau during the 14th century.
On the basis of palaeography, the inscription is dated around the 4th to 5th centuries CE.
A Rajeswara Sarma discussed the historicity and content of Kanva's grammar.Telugu literature was initially found in inscriptions and poetry in the courts of the rulers, and later in written works such as Nannayya's Mahabharatam (1022 AD).During the time of Nannayya, the literary language diverged from the popular language.Further, Tummalagudem inscription of Vishnukundinas belongs to 5th Century CE. The period from 575 CE to 1022 CE corresponds to the second phase of Telugu history, after the Andhra Ikshvaku period.This is evidenced by the first inscription that is entirely in Telugu, dated 575 CE, which was found in the Rayalaseema region and is attributed to the Renati Cholas, who broke with the prevailing custom of using Sanskrit and began writing royal proclamations in the local language.
