A fragment containing two lines of a letter. If the lines are complete, as they appear to be, the column will have been quite narrow and this suggests that we may have part of the right-hand portion of a diptych. A trace at the top left corner may either belong to a previous line in this column or to the end of a line in the left-hand column which overran the fold. The content, though exiguous, is important since the reference to a conturmalis, who is most naturally taken to be at Vindolanda, provides evidence for the presence of cavalry (cf. 159.1 and the correspondence of Lucius the decurion, 299-300).
