Ephemera - from the Greek eph�meros - is the name given to all paper-based work with a specific purpose, not to outlive the contemporary nature of its message. This significant exhibition brings together works dating from 1850 to 1950 belonging to Spain's National Library. Some 700,000 works make up this explosion of colour in the shape of greetings cards, stamps, programs, ID cards, calendars, stickers and games, among other daily objects. Not only is this collection a run-through the evolution of graphic art during much of the 20th century, it also offers an entertaining journey through life.

The Fundaci�n La Caixa offers this exciting encounter with natural fragrances: from the aroma of cinnamon, myrrh or lemon to the nauseous secretion of the civet cat (a small African animal) with which, according to legend, King Solomon once perfumed himself. Por narices. Esencias y fragancias naturales celebrates the power of one of the most ignored senses in this type of events: smell. You simply need to close your eyes to enjoy the smell of the school (a mixture of mandarine, pencil, urea, dust and damp), of the church (dust, incense, wax and damp), of chewing gum or of a burnt forest. An interactive exhibition that will undoubtedly live long in the memory.

After visiting most of Latin America and other Spanish autonomous communities, the exhibition Three centuries of Neapolitan painting reaches Valencia. A total of 53 works by 43 artists, belonging to the artistic movement of 17th to 19th century Naples from the museums of San Martino and Capodimonte and the Valerio collection of Geneva make up this exhibition that begins with the influence of Caravaggio (from 1606 to 1610) and ends with gloomy naturalism. Reality and fantasy combine in these chromatically rich oil paintings and watercolours that surprise with their unique luminosity. ISABELLE BOIX
