Claude Monet’s older sibling is the focus of a landmark Paris exhibit illuminating the hitherto unknown role Leon Monet played in the French impressionist painter’s life and art. Leon was a color chemist and is now understood to have been critical in the emergence of Claude’s commercial success and the famed color palette that created masterpieces like the Water Lilies series. The exhibit curator says “it’s never been known before but without Leon there would not have really been a Monet the artist the world knows today." Leon financed Claude and also employed him as a color assistant. That was a pivotal moment for the painter but also possibly for the emergence of impressionism.

Tourists in Rome checking out the Pantheon, Italy’s most-visited cultural site, will soon be charged a 5-euro ($5.28) entrance fee under an agreement between Italian culture and church officials. The country's Culture Minister said Thursday that the move was a matter of “good sense.” The introduction of an entrance fee comes five years after a previous government shelved plans to start charging visitors 2 euros. Proceeds will be split, with the culture ministry receiving 70% and the Rome diocese 30%, officials say. Entrance will be free to Rome residents, minors, people attending Mass and personnel of the basilica, among others. No date was given for the introduction of the fee.
