Gustave Moreau painted mythology as treasure — Salome dancing in a wall of jewels, the severed head of John the Baptist floating in its own light — and became the painter the Symbolists claimed as a father. He was born in Paris in 1826, died there in 1898, and in between rarely left the house at 14 rue de La Rochefoucauld in the 9th arrondissement that he shared with his parents and rebuilt, at the end, into his own museum.
The second career was the surprise. Appointed professor at the École des Beaux-Arts in 1892, the reclusive Symbolist proved the rarest kind of academic teacher — one who pushed students toward themselves rather than toward him. Henri Matisse and Georges Rouault came out of his studio, and Matisse repeated his advice for decades. The house-museum opened in 1903 with Rouault as its first curator, and still holds some fourteen thousand works arranged much as Moreau left them.
