Read the following excerpt:

Moreover,
in 
the 
middle 
of 
the 
city 
there 
is 
a 
great 
clock ‑‑ that 
is 
to 
say,
a 
bell ‑‑ which 
is struck 
at 
night. 
And 
after 
it 
has 
struck 
three 
times
 no 
one 
must 
go 
out 
in 
the 
city,
 unless 
it 
be 
for
 the 
needs
 of
 a 
woman 
in 
labour,
or 
of
 the
 sick. 
And 
 those 
who 
go
 about 
on
 such
 errands
 are
 bound
 to 
carry 
lanterns 
with
 them. 
Moreover,
 the 
established 
guard 
at 
each 
gate 
of
 the 
city
 is
 1,000 
armed 
men;
not
 that 
you 
are
 to 
imagine
 this 
guard 
is 
kept 
up
 for
 fear 
of 
any 
attack,
but
 only
 as
 a
 guard
 of 
honour
 for
 the
 Sovereign, 
who
 resides
 there,
 and
 to
 prevent
 thieves
 from
 doing 
mischief 
in 
the 
town.

-Marco Polo’s description of Cambaluc
