Split Between Two Collections, Read as One Book

A single ancient manuscript now lives in two countries. The bulk of Papyrus 46's surviving leaves belong to the Chester Beatty Biblical Papyri, the collection assembled by the mining magnate and collector Alfred Chester Beatty and now held in Dublin, but a further block of leaves entered the University of Michigan's Papyrus Collection separately, six leaves acquired in 1931 and twenty four more in 1933. That split traces back to how the manuscript reached the modern antiquities market in the first place: dealers broke up finds and sold portions to different buyers, a common fate for papyri surfacing from Egypt in the early twentieth century, and reuniting the pieces on paper, through publication and cross-referencing, became the work of subsequent scholarship rather than a single acquisition.

Textual critics treat the Dublin and Michigan leaves as one manuscript for every scholarly purpose that matters, numbering them together as Papyrus 46 and reading across the institutional divide as a matter of course. The dating itself remains debated within a roughly fifty year window, the later two centuries CE, itself a reminder of how much interpretive work sits behind even a manuscript this early and this substantial: paleographic dating compares letterforms to other, better dated documents, and reasonable specialists working from the same evidence have not fully converged on one answer.
