This exhibition at Trajan's Markets comprises images of four very different travel experiences by four photographers with contrasting styles. Curated by Arianna Rinaldo, the show features the work of Simon Norfolk from Britain, Elaine Ling from Canada, Giancarlo Ceraudo from Italy and Cristina De Middel from Spain. Through an eclectic mix of travel photos, each photographer interprets the concept of life "on the road", with images from countries as diverse as Afghanistan, Zambia and Cuba. Tues-Sun 10.00-19.00. Mon closed. Museo dei Fori Imperiali and Trajan's Markets, Via VI Novembre 94, tel. 060608.
