"Barlow's intellectual and scholarly qualities are arguably most evident in his editions of complex and technically difficult Latin texts, whose meaning he would elucidate with an almost unrivalled brilliance, and in the writing of biography, a genre about which he thought very deeply, as befitted someone who had contemplated a career as a novelist in his youth. Edward the Confessor (1970), William Rufus (1983) and Thomas Becket (1986) are all very important, and demonstrate a profoundly insightful and carefully reasoned determination to penetrate the religious attitudes of the historians of the 11th and 12th centuries in order to reveal the secular world beneath."
