respecting which they had such exact information.
They were doubtless learned in all the wisdom of
their Chaldaean kinsmen. They were masters, in
fact, of the astronomy of their day, a science for
which the Chaldœans had shown from the earliest
ages the most remarkable aptitude. What the
actual extent of their astronomical knowledge may
have been it would be difficult to say. But it is
certain, from the exact knowledge which later
Chaldaeans possessed respecting long astronomical
cycles, that astronomical observations must have
been carried on continuously by that people for
