These intricate details of spring and summer flowers are from an 18th-century Japanese paper screen by artist Watanabe Shiko. Rinpa is a leading historical school of Japanese painting, established in 17th-century Kyoto, whose artists were known for working in a range of formats, notably screens, fans, hanging scrolls and kimono textiles.
