Adopting Blackburn's paradigm of epic aetiology in contemporary India as developed by Gregory Nagy where the epic is seen as evolving from 'uneven weighting' towards 'even weighting', McGrath finds Karna's epic being subsumed under the weightier Arjuna-epic in the written tradition. Underlying their confrontation is an ancient Vedic substratum: the antagonism between Surya and Indra pointed out by Georges Dumezil (Indra detaches Surya's chariot wheel; Surya's natural mother abandons him and the adoptive mother brings him up). McGrath does not notice that in the Ramayana the same rivalry is perpetuated through Bali and Sugriva, the sons of Indra and Surya respectively, the situation being reversed. It is Surya-Sugriva who has Indra-Bali slain by Vishnu-Rama while, usually, Vishnu helps Indra to slay his adversaries through a trick. This issue warrants deeper examination. 

A good point made is that we never find out how the name of Karna is given. Adhiratha and Radha name him Vasushena and appropriately he is indiscriminately liberal like the Sun. In a footnote, McGrath makes an important point that deserved exploration in the book: the only other 'ear-ringed' heroes are Skanda, and the Maruts. Indra makes the one general of the celestial host against the Titans and has the others as his assistants after an abortive attempt to destroy them in the womb. While in exile, Bhima refers to the enemies being led by Karna as a helmsman steering the Dhartarashtra boat across the raging sea of battle. In the same passage Skanda is celebrated as a great donor. Both unhesitatingly gift Indra what he craves. McGrath does not, however, investigate why Karna becomes infused with the demon Naraka following Duryodhana's capture by the Gandharvas. In the 18th century Tullal songs of Kerala he is the demon Sashrakavacha (thousand-armoured) reincarnated. No Indo-European hero has this demonic aspect. Yet, at the end of epic, Karna is very much a solar hero, celebrated by Kunti as 'A hero, ear-ringed, armoured, splendid like the Sun', seen by Yudhishthira as attended by twelve suns (dvadashaditya sahitam) and finally merging with the Sun (ravim).

McGrath overlooks how Surya browbeats adolescent Kunti into submit to his sexual needs. It is a measure of her strength of character that even as an adolescent girl that she is able to stand up to him partially and obtain boons ensuring her impaired virginity and her son being special. In this, she parallels her grandmother-in-law Matsyagandha vis-'-vis the importunate sage Parashara. In saying that Karna is seen in action first when he accompanies Duryodhana to count cattle in the forest, McGrath forgets the confrontation in Draupadi'ssvayamvara where he retreats, astonished at the 'brahmin' Arjuna's bowmanship. Nor does he note that Karna's much-vaunted prowess is decisively undercut here as also twice more in the cattle-counting and rustling episodes, which Bhishma, Drona and Kripa taunt him with. The contradiction between fidelity to Duryodhana as Karna's declared paramount value and his refusal to fight so long as Bhishma is in the field, and later not taking Yudhishthira prisoner despite having him at his mercy, also remains unexplored.

The most rewarding part of the book is McGrath's exploration of Karna's critical relationships. Like the typical epic hero, Karna has an opposite number who is designated as his 'share': Arjuna. The parallelism is articulated in the very first appearance where Karna does all that Arjuna has displayed in the tournament and then challenges him to a duel. At Kurukshetra, they kill each other's sons. Karna is the only hero on the Kaurava side who converses with gods (Surya, Indra), as Yudhishthira does with Dharma and Kubera, Arjuna with Indra and Shiva. The Krishna-Karna interaction before the war is a clear parallel to and a reversal of the Krishna-Arjuna dialogue that follows. The difference, as McGrath points out, is that here it is Karna who tells Krishna what is going to happen, including his own death, rising to an apocalyptic level that is never Arjuna's. The Karna-Shalya colloquy is yet another variation that stands the Krishna-Arjuna model on its head. Karna's last speech to Shalya is a unique passage in the epic conflating a multitude of emotions: insult, confession, boating, abuse, threat, forgiveness, summing up 'the strange imbalance between potence and irresolution that is so part of his make-up.' 

Karna's fidelity to his word and to liberality for winning fame ' his pre-eminent concern 'raise him to heroic levels that no other character reaches. Yet, Karna is far more mundane in his sufferings and conquests than Arjuna who destroys hosts of Daityas whom the gods cannot defeat, and duels with Shiva himself. Nor is Karna brutal and unfeeling like Bhima who does not even mourn Ghatotkacha and is quite demonic in his deeds. This humanity is what makes him more appealing as an epic hero and is the secret behind the numerous vernacular compositions celebrating him. Karna is defined by two crucial relationships: with Duryodhana it is one of inseparable confidante and advisor, paralleling that of Krishna with Arjuna; with Bhishma it is one of contention arising out of a curious similarity. The origin of both is linked to the heavens (Surya, Dyaus); both emerge out of the Ganga; both are Parashurama's disciples; both are advisors of the Hastinapura court'Bhishma of the titular monarch and Karna of the actual ruler; both command the Kaurava army in turn and are regarded as the major hindrances to Pandava victory.

McGrath isolates six crucial speeches Karna makes to Surya, Indra, Krishna, Kunti, Kripa and Shalya, concluding that his use of speech as a form of assault sets off the epic's movement towards the battlefield. Dhritarashtra refers to Karna as one characterised by bitter speech while Yudhishthira speaks of him as 'one whose teeth are spears and arrows and whose tongue is a sword'. McGrath identifies four levels in Karna's persona where loss increasingly overwhelms him. In the interactions with Indra and Kripa he lacks nothing. In the speech to Krishna a sense of doom looms which he repeats when declaiming to Duryodhana on fate, for he is no longer invincible. Ultimately, shedding tears at his son's death, he is vulnerable like Achilles weeping over Patroklos, and Ravana over Meghanada. His own death soon follows, for the epic hero needs must succumb to mortality to be celebrated eternally.

McGrath makes a valuable point regarding the cult of the hero that is common to occidental and oriental myth when he notes the large number of hero-stones existing in Maharashtra celebrating heroes killed while protecting cattle. He quotes Bhishma from the Shanti Parva stating that heroism is the supreme value in the three worlds, for all is based on the hero. Seeking for sculptural proof of this as in Greek society, he points us to two singular references in the Bhishma and Drona parvas to statues of Kuru kings housed in the temple trembling, laughing, dancing and weeping and to the banners of Draupadi's sons exhibiting images of the Ashvins, Indra, Martus and Dharma. Karna's qualification as a hero is borne out by the fact that both enemies and friends sing laments for him. Further, like the Indo-European hero, Karna is the eternal solitary. Like the Senecan tragic hero, he can very well have as his motto, 'I am myself, alone!'
