Lectures by visiting art authorities, and occasionally by members of the
Gallery staff, are given at 4 p.m. on Sunday afternoons in the
Auditorium.
The subjects are often grouped to form a series treating a single aspect
of art history. Admission is free and no reservations are required. The
A. W. Mellon Lectures in the Fine Arts, a special series commissioned by
the National Gallery, which are subsequently published in book form,
take place during the spring.
