Abstract P. Oxy. I 30 (LDAB 4472, London, British Library, Papyrus 745) is a small fragment of a Latin historical text that is probably the oldest surviving example of a codex. This paper challenges the evidence for dating the fragment to c. 100 CE, and argues on the basis of comparable papyrus fragments that a likelier date is in the first half of the 1 st century CE.
Cillian O’Hogan (Fri,) studied this question.
