I am interested in compiling images of ambos in North America and commenting on them. You are welcomed to submit your example for consideration.
the difference between an ambo and a lectern is that
a lectern holds a book and
an ambo is a monument of the empty tomb.
the difference between an ambo and a pulpit is that
an ambo supports the ritual proclamation of the word of God and
a pulpit supports preaching doctrine.
Cathedral Basilica of St Louis, Missouri
Note the empty space below the loggia from which the word is proclaimed. This is the empty tomb. The medalion facing North is surmonted by the Eagle features the animals representing the four gospels, surmounted by the eagle.
Cathedral of St. Matthew the Apostle, Washington, D.C.
Note the empty space below the loggia from which the word is proclaimed. This is the empty tomb. The placement of the ambo and its ritual use, however, appear to be more like that of a pulpit than an ambo.
