Which lines in this excerpt from "easter, 1816" by w. b. yeats suggest that the speaker had only a limited acquaintance with the people he is writing about?

i have met them at close of day
coming with vivid faces
from counter or desk among grey
eighteenth-century houses.
i have passed with a nod of the head
or polite meaningless words,
or have lingered awhile and said
polite meaningless words,
and thought before i had done
of a mocking tale or a gibe
to a companion
around the fire at the club,
being certain that they and i
but lived where motley is worn:
all changed, changed utterly:
a terrible beauty is born.
. .
hearts with one purpose alone
through summer and winter seem
enchanted to a stone
to trouble the living stream.

the thousand and one nights – or, as i prefer to call them in the following forpurely practical reasons: the arabian nights – as we perceive them three hundredyears after antoine galland’s epochal french adaptation bear a distinct arabicimprint. meanwhile, the commonly accepted model for their textual historyacknowledges various stages in the conceptualization and effective formation ofboth the collection’s characteristic frame story and the embedded repertoire. thevast majority of tales in the preserved manuscripts of the nights has beenintegrated into the collection during two periods of arabic influence, the so-calledbaghdad and cairo periods (gerhardt 1963: 115–374). these “arabic” stages arepreceded by an iranian version, probably dating to pre-islamic times, which in itsturn profits from both structural devices and narrative contents originating fromindian tradition. considering the eminent position that iran and iranian culturehold in the early stages of the textual history of the arabian nights, surprisinglyfew details are known concerning the collection’s relation to and its actualposition within the iranian cultural context. in the following, i will discuss linksbetween the arabian nights and iranian culture on several levels. in surveyingthese links, i will treat five major areas: (1) the iranian prototype of the nights; (2) tales of alleged persian origin; (3) persian characters within the tales; (4)persian translations of the arabian nights; and (5) the position of the arabiannights in modern iran
