must be viewed as the climax of a movement that had its roots in the spirituality of the Christian concept of the divinity." The events of the seventh century, which was a period of major crisis for the Byzantine Empire, formed a catalyst for the expansion of the use of images of the holy and caused a dramatic shift in responses to them. Whether the acheiropoieta were a symptom or cause, the late sixth to eighth centuries witnessed the increasing thinning of the boundary between images not made by human hands, and images made by human hands. Images of Christ, the Theotokos and saints increasingly came to be regarded, as relics, contact relics and acheiropoieta already were, as points of access to the divine. By praying before an image of a holy figure, the believer's prayers were magnified by proximity to the holy. This change in practice seems to have been a major and organic development in Christian worship, which responded to the needs of believers to have access to divine support during the insecurities of the seventh century. It was not a change orchestrated or controlled by the Church. Although the Quinisext council did not explicitly state that images should be prayed to, it was a legitimate source of Church authority that stated images of Christ were acceptable as a consequence of his human incarnation. Because Jesus manifested himself as human it was acceptable to make images of him just like it was acceptable to make images of the saints and other humans. The events which have traditionally been labelled 'Byzantine Iconoclasm' may be seen as the efforts of the organised Church and the imperial authorities to respond to these changes and to try to reassert some institutional control over popular practice. The rise of Islam in the seventh century had also caused some consideration of the use of holy images. Early Islamic belief stressed the impropriety of iconic representation. Earlier scholarship tried to link Byzantine Iconoclasm directly to Islam by arguing that Byzantine emperors saw the success of the early Caliphate and decided that Byzantine use of images (as opposed to Islamic aniconism) had angered God. This does not seem entirely plausible however. The use of images had probably been increasing in the years leading up to the outbreak of iconoclasm. One notable change came in 695, when Justinian II put a full-faced image of Christ on the
