From Alan Bowman and David Thomas, Vindolanda: the Latin writing
tablets London: Society for the Promotion of Roman Studies,

The two letters addressed to Lucius are assigned to different
periods (3 and 5 respectively), but we are tempted to refer them
to the same individual, who might have been at Vindolanda for a
period of several years, or on more than one posting. One of the
letters gives him the title of decurio (299);
the subject-matter of the other, the despatch of two cavalrymen,
would be appropriate to a decurion (300).
