   Synonym: perlūstrō

2. (figuratively) to circle, move in a circle around. (because the priest offering such sacrifice did so)
   • 9 CE, Ovidius, Ibis 111–112:

     Exul inops errēs aliēnaque līmina lūstrēs,
         exiguumque petās ōre tremente cibum.

     May you wander as a poor exile and go round others' thresholds,
         and ask with a trembling mouth for a bit of food.

In sense 1, from lustra (“brothel, place of debauchery”) +‎ -ō (noun-forming suffix) (compare lustror (“to frequent brothels”)).^[1] Sense 2 is possibly a reinterpretation based on the alternative sense of lustra (“wilds, woods, forest”) or influenced by the etymologically unrelated verb lūstrō (“wander over, traverse, roam”) (see above).
