I've been enjoying leading some seminars for the Logos Summer School in Oxford. Yesterday we looked in some detail (!) at a page of Codex Vaticanus and enjoyed reading some of the text of Romans. Some interesting details are seen in one small portion of the page we were looking at (page 1460 according to the codex; page 1464 according to the online images).
The NA28 text has: Ἀσπάσασθε Πρίσκαν καὶ Ἀκύλαν τοὺς συνεργούς μου ἐν Χριστῷ Ἰησοῦ, οἵτινες ὑπὲρ τῆς ψυχῆς μου τὸν ἑαυτῶν τράχηλον ὑπέθηκαν.
Feel free to discuss this in the comments: 'what do you see here?'
