"Upper limit" of PIE

[Hans Holm]

LT>The archaeologists' calendar runs backward in time from the bottom of
LT>the page to the top.  So, a "high" date is earlier than a "low" date,
LT>and an "upper" limit is a *terminus non ante quem*, while a "lower"
LT>limit is a *terminus non post quem".

.. <simple reason: from an archaeologists's view a higher layer of earth
is younger;-)
