Letters read by a previous modern observer, but which cannot now be read.
The text which was visible to a previous editor but is now lost or illegible should be indicated with a supplied element with evidence with a value of "previouseditor".
In most epigraphic/papyrological styles this text will be displayed with underline only (similarly to Parallel Copy), and so it is largely academic whether the required reason attribute has a value of "lost" or the more generic "undefined", but in the Duke Databank the text may also be enclosed in square brackets to indicate the fact that the text is now completely lost (as opposed to merely unclear, corrupt or uncertain).
