An  inscription at Atkuru of the Rashtrakuta king Krishna III's period, depicts the heroic deeds of a brave hound, Kali. The illustration of the hero-stone is as informative as the inscription itself. Its master, Manalar, has made sure that his loved Kali is depicted stronger and mightier than the wild boar.

The memorials also provide an illustrated account on different facts of social and religious life of a given period. However, this unique source of information is not put to full use by scholars. Researchers interested in dress, ornaments, hair style, flags, weapons, emblems, musical instruments, domestic scenes, arts, crafts, utensils, pastimes of the period can rely upon this authentic information
