most likely a misspelling of HRWTHSAN, ordinarily met as ERWTHSAN,
"(they) asked, inquired, queried." Mah very "own" pc can't come up
with anything else that looks nearly like it (of course, is well past
midnight in Athens and batteries kind of low right now, but I still would
wager on it. Trust it). Think now you can figure grammar, if you like.
