During this holiday season, the National Gallery of Art has brought "tidings of great joy" to many art lovers. It has opened blockbuster exhibits "Titian, Prince of Painters," "Anthony van Dyck," "Eva-Ave: Woman in Renaissance and Baroque Prints" and others.

- The Titian exhibition commemorates the 500th anniversary of his birth. In fact, it is the first exhibition in more than 50 years to cover the artist's long, influential career.In addition to nearly 50 of Titian's portraits, mythologies and religious compositions are three of his ceiling paintings. One is mounted with 19 panels that originally surrounded it.

Masterpieces from all over the world were gathered for the exhibition: 10 from Venice, six from the Museo del Prado and paintings from other museums and private collections.

Thirteen paintings were recently cleaned and restored - many expressly for the exhibition. They include "Eleonora Gonzaga," "Francesco Maria della Rovere" and "Feast of the Gods." The latter is attributed to Bellini. However, Titian painted the impressive landscape.

"Titian, Prince of Painters" will continue through Jan. 27 in the West Building of the National Gallery of Art.

- On display in other rooms of the West Building are more than 100 oil paintings and oil sketches by Flemish master Anthony van Dyck. The exhibit commemorates the 350th anniversary of the artist's death.

J. Carter Brown, director of the National Gallery of Art, proudly said, "A Van Dyck exhibition of this magnitude has not been mounted since 1899 in Antwerp and London. This show demonstrates Van Dyck's extraordinary artistic talent - not only his brilliance as a portraitist, but the evocative qualities of his religious and mythological paintings.

"Cupid and Psyche," an exquisite oil painting owned by Queen Elizabeth, was cleaned specially for this show. This and other mythological scenes and religious paintings created during his second Antwerp period, 1622-1632, are among his greatest works.

But Van Dyck's portraiture are equally impressive. In fact, he remains one of the greatest portrait-painters of all time.

This exhibition of Van Dyck masterpieces remains at the National Gallery of Art through Feb. 24, 1991.

- Another exhibition drawing crowds, "Eva/Ave: Woman in Renaissance and Baroque Prints," is composed of 154 prints of the 15th through the 17th centuries. It is divided into thematic sections, including the Virgin and saints, the Worthies, Eve, Venus, Fortuna and lovers. The prints are by a wide range of master printmakers including Durer, Mantegna, Rembrandt and Schongauer.

This exhibit will remain on display through April 28, 1991, in the east tier, ground floor of the West Building.

- Other exhibits being featured at the gallery are "The Art of Paul Strand," through Feb. 3, 1991; "The Art of Glass: Masterpieces from the Corning Museum," through March 17.
