The very long tail of a at the beginning of the line is noteworthy.
impetrauerim: although the first two letters are very faint, the reading is not in doubt (cf. 255.ii.12).
mi: for the contracted form cf. 343.i.10, ii.23. After ut only the tops of letters survive.
his .b[: the last letter might be l. Thereafter only traces of the tops of letters survive.
Both elements of the name are extremely common. For Vettius cf. 214.1 note; Severus occurs in 349.6 and 301.i.1 (the latter probably a slave). Vettius Severus does not occur elsewhere in the Vindolanda texts and is not likely to be identical with either of the other individuals with this cognomen. The attestation of T.Vettius Severus, the prefect of cohors iv Hispanorum (PME V81), is too late to be relevant. See next note.
..[: the only certain traces are of the tops of two letters (there may be some further traces to the right but it is impossible to be sure whether these are ink). It is probable that these belong with the name of the addressee rather than the sender, since they are not written on an upward slant. The traces are compatible with pr and the spacing would allow pr[aef(ecto) coh(ortis). It must be stressed, however, that this is extremely uncertain (cf. VRR II, 27, 30).
