The practice of idolising kings by making their life-sized portraits, however, did not settle well in pre-modern India and the Kushan period emerges as a sort of parenthesis in this respect. No free-standing big portrait of Ashoka, the Maurya emperor, was ever made in his lifetime (or after, until the modern times) even though he had a well-thought-out distribution of tall stone columns and rocks carrying his voice across his vast empire in the form of edicts.
Small, generic portraits of the Magadha king Ajatashatru, Maurya king Ashoka, and some Satavahana and Ikshavaku kings are indeed found as part of the iconographic programme of Buddhist stupa complexes. These are to be seen in the sculptural remains from Bharhut and Sanchi in Central India, and Kanaganahalli in Karnataka, for example, and belong to the early centuries before and after the Common Era.
The important point here is that these rather small sculptural representations are not portraits of political power. Nor are they ‘portraits’ in the sense that specific portraits of kings were produced in Rome. Rather, royalty is postured in all of these early Indian instances as being in service of the Buddha and the Sangha, conveying the voice of the Buddhist community who patronised the making the of stupa complexes. The Buddha himself, who was born as Siddhartha, the Shakya prince, was idolised and deified many centuries after his death as the enlightened being and as a chakravarti (universal ruler) but only in the sense of a religious head and not as a king.
After the Kushans, the Gupta kings who ruled over a large empire did not carry forward the Kushan practice of idolising kings through the commissioning of large portraits, even though Gupta coins carried different typological images of their kings. The aesthetics of political power in the courts of these kings and of their successors in various parts of India was exercised by an assertion of kingly power through divine intervention: as gods in heaven, so the kings on earth who were sanctioned divine authority to rule.
Consequently, generic (and not specific) portraits of kings were almost always found as a relatively insignificant part of, and in the larger context of, religious monuments. This is true of the seventh-century portraits of Pallava kings Mahendravarman-I and Narasimhavarman-I at Mamallapuram and the 11th-century painted portrait of Rajaraja Chola-I in the interior of the Great temple of Brihadishvara at Tanjore in Tamil Nadu; the 12th-century image of King Vishnuvardhana at the Chennakeshava temple in Belur, Karnataka; and the 13th-century portrait sculptures of the Ganga King Narasimhadeva from the Sun temple in Konark, Orissa.
