AN elegant woman gazes out from her portrait with expressive eyes, a gilded wreath worn in her hair and a gentle, questioning look on her face.

She is one of the 2,000-year-old "Faces of Fayum", startlingly realistic funerary – or mummy – portraits painted after Egypt became part of the Roman empire.

The fragile portraits dating from the first to third centuries AD – painted on thin wooden panels and designed to be placed over the face of mummies – will go on display in Rome in what organisers hail as a "milestone" collaboration between Italy and Egypt.

"Egypt and Rome, the Faces of Fayum", opening Wednesday at Rome's Ara Pacis museum, also includes mummies, masks, shrouds, jewellery, marble busts and statuary.
