On the evening of 15 August Dr Alexander Lingas offered a lecture on Greek Liturgical Manuscripts at the Ioannou Centre for Classical and Byzantine of the University of Oxford (where he is also a Fellow of its European Humanities Research Centre). Offered for the students and faculty of Oxford’s annual Greek Palaeography Summer School, this talk surveyed the contents and use of manuscripts relating to worship in Byzantium. Dr Lingas emphasised that Byzantine liturgical manuscripts first and foremost reflected the needs of their users: priests, readers, soloists, choristers, and so on. In response to a request from the Summer School’s director, he ended his presentation by singing an Alleluia from a 13th-century chant manuscript.
