Here is another painting by Lawrence Alma-Tadema I just had to post, it is so incredible, as are the story behind it and his biography. Because Alma-Tadema was painting this picture during the winter, he arranged to have roses sent weekly from the French Riviera for four months to ensure the accuracy of each petal. en.wikipedia.org/wiki/Lawrence_Alma-Tadema#Personality
The Roses of Heliogabalus(1888) Roman emperor from AD218 to 222 The painting is in the collection of Juan Antonio Pérez Simón of Mexico. Helio must have said, "It's a warm day. Let's have a picnic."
