I see no reason not to take tech midcuarta as drinking hall, but I would
also suggest that a Meath-mid-mead-Maeve connection -- drinking a health
to the local aspect of the Mother Goddess -- might also have been in the
minds of the inbibers as a multi-layered poetic pun.
The linear earthwork at the Hill of Tara known as Tech Midcuarta has for
some years now been described as a ceremonial entrance way, although the
old OPW "Tech Midcuarta" sign remains for reasons even the official
staff can't explain. Gerard Clarke (if I have his name right), who was a
guide and I think an archaeologist at Tara some 10 years ago, felt the
Banquet Hall was next to the churchyard where the statue of Saint
Patrick was recently erected.
A couple years ago, in a lecture to the Royal Society of Antiquaries of
Ireland, Richard Warner of the Ulster Museum in Belfast, who
mischievously ruffled a lot of feathers by re-mooting the
Romans-in-Ireland theory in the mid-90s, described the earthwork as a
god line. It is aligned north-south, and Warner said that if you
continue the line north to the Antrim coast it strikes a number of
significant ancient sites. It is meant to be a line travelled by gods or
super heroes, not humans, because it also passes over natural obstacles
such as cliffs.
In response to my question whether a line drawn south of Tara might
strike the lost Aenach Carmon, he said he had not considered what might
lie to the south.
