But last week, the Gem?ldegalerie Alte Meister in Dresden, Germany, where she's been housed for most of her long life, has finally unveiled an amorous secret, hidden long ago beneath layers of paint.Ahead of its upcoming show about the celebrated Dutch painter, the museum has released an image of a drastically changed "Girl Reading a Letter at an Open Window," which the Dutch artist painted between 1657 and 1659. Following a painstaking four-year-long restoration, the empty wall now shows a monumental painting of Cupid, discovered by X-ray in 1979, but now revealed for the first time.The Tokyo Paralympics officially came to an end on Saturday as the closing ceremony took place at the Olympic Stadium.While the ceremony -- which included singing, dancing, and a parade of nations -- drew to its conclusion in the Japanese capital, the Paralympic flag was formally passed on to Paris and accepted by the city's mayor, Anne Hidalgo, in anticipation of hosting the 2024 Games.It marks the end of nearly two weeks of Paralympic sport, during which China topped the medal table with 96 golds and 207 medals in total. Great Britain was second with 41 golds and USA third with 37."Together, against the odds, we did it," said International Paralympic Committee President Andrew Parsons during his closing ceremony speech."The Tokyo 2020 Paralympic Games have not just been historic -- they have been fantastic."In 12 magical days, athletes gave the world confidence, happiness, and hope. Athletes broke records, athletes won hearts, athletes opened minds. Importantly, athletes changed lives."The ceremony itself lasted about two hours and -- as has been the case for much of the Olympics and Paralympics -- took place in a near-empty stadium without spectators amid the Covid-19 pandemic.It celebrated youth culture with performances that included break-dancing, BMX biking, roller-skating, and choirs of children.Many of the performers were dressed in bright, fluorescent colors and displayed LED lights as they walked through the stadium.During the parade of nations -- which had fewer athletes participating compared to usual closing ceremonies as many had already returned home -- performers dressed in purple and white smocks danced, clapped, and waved athletes into the stadium.It took place around a model cityscape of Tokyo that had been erected inside the stadium, and parading athletes affixed silver badges onto a tower that had been laid down on the floor.Crown Prince Akishino, the heir to Japanese Emperor Naruhito, watched over proceedings from the stands.
