Constantinople was in a state of renewal and reconstruction from the second half of the ninth century to the end of the tenth century. Old manuscripts of ancient texts were being surveyed and collected in a campaign commissioned usually by imperil authority. In the process of transliteration, many manuscripts of old uncial were converted to minuscule. This process allowed extensive content to be copied and recopied more efficiently. Transliteration can be viewed on the parchment of the oldest manuscript of the Apocalypse of Anastasia dated to 1340. Palimpsest, the folios of Bodleian Selden Supra 9 was compiled from four earlier manuscripts which consisted of two-tenth century liturgical works, an Old Testament lectionary dated near the turn of the eleventh century which the Apocalypse of Anastasia appears on top, and a ninth century New Testament lectionary.
