It's only the size of a shoebox, carved with the broken-off foot of an ancient Greek goddess.

But Greece hopes the 2,500-year-old marble fragment, which has arrived on loan from an Italian museum, may help resolve one of the world's thorniest cultural heritage disputes and lead to the reunification in Athens of all surviving Parthenon Sculptures — many of which are in the British Museum.

Pope Francis suggested Monday that getting vaccinated against the coronavirus was a "moral obligation" and denounced how people had been swayed by "baseless information" to refuse one of the most effective measures to save lives.

Francis used some of his strongest words yet calling for people to get vaccinated in a speech to ambassadors accredited to the Holy See, an annual event in which he takes stock of the world and sets out the Vatican's foreign policy goals for the year.

Israel's national library says the number of visitors to its Arabic website more than doubled last year, driven by a growing collection of digitized materials and an aggressive outreach campaign to the Arab world.

Around 650,000 users, predominantly from the Palestinian territories, Egypt, Saudi Arabia, Jordan and Algeria, visited the National Library of Israel's English and Arabic sites in 2021, said library spokesman Zack Rothbart.

Employees and schoolchildren juggled work and studies with weekly Muslim prayers on the first ever working Friday in the United Arab Emirates as the Gulf country formally switched to a Saturday-Sunday weekend.

One of the Israel Museum's biggest patrons, American billionaire Michael Steinhardt, approached the flagship Israeli art institution in 2007 with an artifact he had recently bought: a 2,200-year-old Greek text carved into limestone.

Orthodox Christians in Russia, Serbia and other countries began Christmas observances Thursday amid restrictions aimed at dampening the spread of the coronavirus, but few worshipers appeared concerned as they streamed into churches.

The majority of Orthodox believers celebrate Christmas on Jan. 7, with midnight services especially popular. The churches in Romania, Bulgaria, Cyprus and Greece mark it on Dec. 25 along with other Christian denominations.

Pope Francis risked the ire of the world's childless dog and cat owners Wednesday, suggesting people who substitute pets for kids exhibit "a certain selfishness" 

Rembrandt van Rijn's iconic and huge painting "The Night Watch" is now also a supersized museum photo delivered right to your laptop in unsurpassed detail.

The Amsterdam Rijksmuseum on Monday put on its digital portal what it called "the most detailed photograph of any artwork" ready for assessment by scientists and art lovers alike. It is expected to draw widespread interest especially since the museum is closed because of coronavirus measures.

Pope Francis urged the world to "roll up our sleeves" for peace in a New Year's message Saturday, telling the faithful to keep positive while working to build a better society.

They both carved out sterling reputations as military and political leaders over years of public service. But both also saw their legacies tarnished by their actions in the long, bloody war in Iraq.
