The present study offers a comparative analysis of colophons written in Arabic by Christian scribes at the monasteries of Saint Chariton, Saint Sabas, and Saint Catherine in the ninth and tenth centuries CE. These monasteries have played a crucial role in the formation of the early Christian Arabic manuscript tradition. The colophons of these manu- scripts provide the most immediate access to the socio-cultural milieu of their producers. The present study is based on a selection of 20 colo- phons, which are explicitly connected to one of the three monasteries. Our main aim is to draft a typology of early Christian Arabic colophons as a means to investigate the various issues surrounding emergent Chris- tian Arabic scribality. Additionally, we will discuss paleographical fea- tures of the handwriting of the scribes who authored the colophons dis- cussed here. As we will show, these can be used to connect anonymous colophons and manuscripts without colophons, at least with some prob- ability, to the workshops of these monasteries. Overall, our aim is to highlight the microhistorical significance of early Christian Arabic colo- phons, which not only offer spatio-temporal, prosopographical, social, intellectual, and, to some extent, economic coordinates for the contex- tualisation of early Christian Arabic manuscript production, but also al- low us to catch a glimpse of early Christian Arabic scribal self- perception.
