On a temperate spring day last week, works of art from Audrey Flack’s light and airy studio in East Hampton were being gently borne to the Gary Snyder Gallery in the Chelsea district of Manhattan, where they will be on view from next Thursday through May 19. They range from tabletop size to flat-out enormous, and they all showcase Ms. Flack’s passion for the “sacred feminine” — the women heroes of mythology and religious iconography.
