VATICAN CITY • Putting more masterpieces in Michelangelo's Sistine Chapel to join his ceiling frescoes and Last Judgment wall might seem as superfluous as adding more diamonds to the Crown Jewels.

But the creator of those masterpieces is Raphael, Michelangelo's Renaissance contemporary and rival, so the Vatican has made an exception for a brief stay.

For the first time in centuries, all 12 tapestries designed by Raphael have been hung on the lower walls of the Sistine Chapel in Vatican City as part of celebrations marking the 500th anniversary of the artist's death.

Vatican Museums director Barbara Jatta said: "They were conceived for this space and so we thought it was the best way to celebrate."

The tapestries - which were woven in Brussels by the famed studio of Pieter van Aelst from Raphael's sketches - depict scenes from the Acts of the Apostles, such as The Stoning Of Saint Stephen and Saint Paul Preaching In Athens.

This week, they are back in the Sistine Chapel, where they were between the time Michelangelo finished painting the ceiling in 1512 and when he began painting the massive Last Judgment wall behind the main altar in 1536.

All 12 tapestries - made with silk, wool and gold and silver thread - have been painstakingly restored by Vatican Museum conservationists in the last 10 years.

"This place is of universal importance not only for visual arts, but also for our faith," Ms Jatta said, standing in the Sistine Chapel. "So we really want to share this beauty with people, even if only for one week."

Seven of the tapestries, commissioned by Pope Leo X, were hung in the chapel on Saint Stephen's Day, Dec 26, 1519.

Raphael was probably there to see them, but he died four months later at the age of 37. The others were finished after his death.

Exhibition curator Alessandra Rodolfo said: "The last record that we have of all of them being hung in the Sistine is from the late 1500s."

Previous exhibitions, some of which lasted only a few hours or a day, included only the 10 larger tapestries, some measuring about 6m by 5m.

Two of the 12 are narrow and hung vertically as borders.

Selected tapestries are normally on display on rotation behind glass in climate-controlled spaces in the Vatican Museums.

The Vatican Museums' conservationists and restorers allowed all 12 of the delicate tapestries to be put on show at the same time for only a week, in part to protect them and in part because some will be on loan to other museums.

One will soon be going to Rome's Quirinal Palace's Scuderie museums and another to the National Gallery in London later this year.

Said Ms Jatta: "It's exactly what Pope Francis is asking us, which is to share and to be a museum open to everybody, and to share our beauty."
