Inscription of Antanavarman, 5-6th century CE:

Om! He, Anantavarman who was the excellent son, captivating the hearts of

mankind, of the illustrious Sardula, {and) who, possessed of very great virtues, adorned by his own (high) birth the family of the Maukhari kings,— he, of unsullied fame, with joy caused to be made, as if it were his own fame represented in bodily form in the world, this beautiful image, placed in (this) cave of the mountain Pravaragiri, of (the god) Krishna.

(Line 3.)--The illustrious Sardula, of firmly established fame, the best among chieftains, became the ruler of the earth; -he who was a very Death to hostile kings; who was a tree, the fruits of which were the (fulfilled) wishes of (his) favourites; who was the torch of the family of the warrior caste, that is glorious through waging many battles; (and) who, charming the thoughts of lovely women, resembled (the god) Smara.

(L. 5.)— On whatsoever enemy the illustrious king Sardula casts in anger his scowling eye, the expanded and tremulous and clear and beloved pupil of which is red at

the corners between the uplifted brows,— on him there falls the death-dealing arrow, discharged from the bowstring drawn up to (his) ear, of his son, the giver of endless pleasure, who has the name of Anantavarman.
