Some features were added to the Chandragupta basadi by famous Hoysala sculptor Dasoja in the 12th century. The decorative doorjambs and perforated screen windows which depict scenes from the life of King Chandragupta Maurya are known to be his creation. The Panchakuta Basadi at Kambadahalli (five towered Jan temple) of about 900 with a Brahmadeva pillar is an excellent example of Dravidian art. The wall niches here are surmounted by torana (lintel) with carvings of floral motifs, flying divine creatures (gandharva) and imaginary monsters (makara) ridden by Yaksas (attendants of saints) while the niches are occupied by images of tirthankars themselves. Other notable constructions were the Vallimalai Jain caves and the Seeyamangalam Jain temple during the reign of Rachamalla II, and the 5th or 6th century Parshvanatha temple at the Kanakagiri Jain tirth. The Gangas built many Hindu temples with impressive Dravidian gopuras containing stucco figures from the Hindu pantheon, decorated pierced screen windows which are featured in the mantapa (hall) along with saptamatrika carvings (seven heavenly mothers). Some well known examples are the Arakeshvara Temple at Hole Alur, Kapileswara temple at Manne, Kolaramma temple at Kolar, Rameshvara temple at Narasamangala, Nagareshvara temple at Begur and the Kallesvara temple at Aralaguppe. At Talakad they built the Maralesvara temple, the Arakesvara temple and the Patalesvara temple. Unlike the Jain temples where floral frieze decoration is common, Hindu temples were distinguished by friezes (slab of stone with decorative sculptures) illustrating episodes from the epics and puranas. Another unique legacy of the Gangas are the number of virgal (hero stones) they have left behind; memorials containing sculptural details in relief of war scenes, Hindu deities, saptamatrikas, Jain tirthankars and ritual death (such as the Doddahundi hero stone). Language The Western Gangas used Kannada and Sanskrit extensively as their language of administration. Some of their inscriptions are also bilingual in these languages. In bilingual inscriptions the formulaic passages stating origin myths, genealogies, titles of Kings and benedictions tended to be in Sanskrit, while the actual terms of the grant such as information on the land or village granted, its boundaries, participation of local authorities, rights and obligations of the grantee, taxes and dues and other local concerns were in the local language. The usage of these two languages showed important changes over the centuries. During the first phase (350–725), Sanskrit copper plates dominated, indicating the initial ascendancy of the local language as a language
