A swirl of red fabric flashes across a screen in a video installation, foregrounding the helical staircase of architect Lina Bo Bardi’s Museu de Arte Moderna da Bahia in Salvador, Brazil that mirrors the curving stairs opposite in the Frank Gehry–designed Williams Forum at the Philadelphia Museum of Art. It is on one of a pyramid of nine screens there across which Isaac Julien displays the life and work of Italian-born Bo Bardi (1914–92), in an arrangement suspended within the cathedral-like space.

Entitled Lina Bo Bardi—A Marvellous Entanglement, the London artist and filmmaker’s 40-minute video homage to this giant of Brazilian Modernism opened in late January and runs through May 29.
