It has been a bad week for Louvre director Laurence des Cars but next week could be even worse.

That is when she is due to give evidence to the official inquiry into the $102 million daylight jewelry heist that rocked the Paris museum last year.

Her appearance in front of the committee, along with Culture Minister Rachida Dati, comes after it released its interim assessment which said the theft revealed "systemic failures at the museum".

The inquiry's co-leader Alexandre Portier said management was "failing", before adding that in other "countries and institutions" those failings would have led to the director stepping down.

Des Cars offered her resignation after the October 19 break-in, but it was refused by President Emmanuel Macron. Arrests have been made in the case but none of the stolen jewelry has been found.

Tributes have been paid to mosaic artist Isaiah Zagar who died yesterday aged 86.

He created more than 50,000 square feet of mosaic works in his home city of Philadelphia with hundreds of other works as far afield as Mexcio and Chile.

His lasting legacy is Philadelphia's Magic Gardens which is based in the former studio where he worked with his wife Julia and which is now run as a non-profit museum open to the public.

Its executive director Emily Smith said: "In his 86 years, Isaiah became one of the most renowned mosaicists on earth, working from sunrise to sunset each day; creating hundreds of public mosaics, dozens of buildings and facades, and thousands of drawings, paintings, prints, and photographs."

The number of works by 135 Afro-Brazilian artists being voluntarily returned to the country having been part of the collection of artist Barbara Cervenka and art historian Marion Jackson in Detroit.
