Perhaps the following may be of some use in clearing up this point.
In the _Graphic Illustrator_, a literary and antiquarian miscellany
edited by E.W. Brayley, London, 1834, at p. 14, towards the end of
an article on the Tudor Style of Architecture, signed T.M. is the
following:--
"This room (talking of the great halls in old manor-houses)
was in every manor-house a necessary appendage for holding
'the court,' the services belonging to which are equally
denominated 'the homage,' with those of the king's palace. The
_dais_, or raised part of the _upper end_ of the hall, _was
so called_, from the administration of justice. A _dais-man_
is still a popular term for an arbitrator in the North, and
_Domesday-Book_ (with the name of which I suppose every one to
be familiar) is known to be a list of manor-houses."
