At the outset of The Faerie Queene Book 5, Edmund Spenser defines justice as “Most sacred vertue” and proclaims that he would display the power of the justice in the work. The kind of justice Artegall carries out, however, does not seem to fulfill the poet’s initial declaration, for the knight of justice somehow fails to achieve neither justice absolute, nor equity through his adventures. Furthermore, when confronted with an ultimate injustice manifested in the person of Radigund in Canto 5, the knight gives up his battle and yields himself to her slavery despite the fact that he dominates the battle. What kind of justice, then, Spenser would want to portray in the work? This paper is to examine different aspects of justice that Artegall carries out-or fails to achieve-in Book 5 of The Faerie Queene, so as to understand the poet"s idea of justice. Although critics argue that while displaying an absolute justice, Artegall lacks equity, another important aspect of justice, the earlier episodes do not show that the knight carries out the fair justice in terms of the weight of the crimes. Whereas his justice becomes quite harsh towards those who usurp the social, political, and religious stability of the poet’s time, he shows leniency to the individuals who commit personal crimes or who belong to the same society as himself. Thus, we may conclude that Spenser’s justice portrayed in the work is arguably misogynic, imperialistic, and on the side of British throne. However, if Artegall’s justice is clearly within “God’s providence,” which cannot be fully understood by human beings, he has to keep trying to fulfill the justice in spite of his own inability to achieve it, and perhaps this is the message Spenser sends through Artegall’s adventures.
