The existence and literary use of these Prākrits is most interesting in the history both of the language and the literature, for they present archaic features which place them on the same plane of change as Pāli and the dialects of the older inscriptions. They may be set beside the inscriptions in the Sītābengā and Jogīmārā caves on the Rāmgarh hill, which both show lyric strophes. The influence of the Kāvya style in Sanskrit can be traced obviously in the later Nāsik inscription in Prākrit of the second century A.D., and even in the inscription of Khāravela of Kalin̄ga perhaps in the second century B.C. [159] We cannot, therefore, see any plausibility in the idea of the gradual adaptation of Sanskrit, a sacred language, to belles lettres; on the contrary the dramas show that the Prākrits in literature were already under the influence of the Sanskrit Kāvya. 4. THE METRES Scanty as the fragments are, they display another feature significant of the development of the drama on the classical lines. The metres employed are very numerous, as is natural in a poetry in which the verse serves essentially the purpose of displaying the skill of the writer. In addition to the Çloka we find the Upajāti (⏓ - ⏑ - - ⏑ ⏑ - ⏑ - -), the Çālinī (- - - -, - ⏑ - - ⏑ - -), Vaṅçasthā (⏑ - ⏑ - - ⏑ ⏑ - ⏑ - ⏑ -), Praharṣiṇī (- - -, ⏑ ⏑ ⏑ ⏑ - ⏑ - ⏑ - -), Vasantatilaka (- - ⏑ - ⏑ ⏑ ⏑ - ⏑ ⏑ - ⏑ - -), Mālinī (⏑ ⏑ ⏑ ⏑ ⏑ ⏑ - -, - ⏑ - - ⏑ - -), Çikhariṇī (⏑ - - - - -, ⏑ ⏑ ⏑ ⏑ ⏑ - - ⏑ ⏑ ⏑ -), Hariṇī (⏑ ⏑ ⏑ ⏑ ⏑ -, - - - -, ⏑ - ⏑ ⏑ - ⏑ -), Çārdūlavikrīḍita (- - - ⏑ ⏑ - ⏑ - ⏑ ⏑ ⏑ -, - - ⏑ - - ⏑ -), Sragdharā (- - - - ⏑ - -, ⏑ ⏑ ⏑ ⏑ ⏑ ⏑ -, - ⏑ - - ⏑ - -), and Suvadanā (- - - - ⏑ - -, ⏑ ⏑ ⏑ ⏑ ⏑ ⏑ -, - - ⏑ ⏑ ⏑ -), the last of these metres being almost a stranger to the drama, though it appears in Bhāsa, in the Mudrārākṣasa, and once in Varāhamihira. The tendency to seek sound effects is clear in a Çikhariṇī verse.
