  The obscuration of a celestial body that covers another one in the background
will be called a ``hierarchical eclipse''. The most obvious case is that a star
or a planet will be hidden from sight by the moon during a lunar eclipse. Four
objects of the solar system will line up then. We investigate this phenomenon
with respect to the region of visibility and periodicity. There exists a
parallax field constraining the chances for observation. A historic account
from the Middle Ages is preserved that we analyse from different viewing
angles. Furthermore, we provide a list of events from 0 to 4000 AD. From this,
it is apparent that Jupiter is most often involved in such spectacles because
its orbit inclination is small. High-inclination orbits reduce the probability
to have a coincidence of an occultation of that object with a lunar eclipse.
