French historian Michel Pastoureau continues his large-scale project dedicated to the history of color in Western European societies from Ancient Rome to the present day. The UFO publishing house has already published the books "Blue", "Black", "Red" and "Green", as well as "Diabolical Matter. The history of stripes and striped fabrics". The new book is dedicated to the yellow color, which is little present in the daily life of modern Europe and is poorly represented in official symbols. However, this was not always the case. People of the past saw it as a sacred color — the color of light, warmth, wealth and prosperity. The Greeks and Romans gave it a special place in religious rituals, and the Celts and Germans associated it with wealth and immortality. The lowering of the status of yellow occurred in the Middle Ages. On the one hand, it has become the color of bitter bile and demonic sulfur - a sign of lies, avarice, sometimes even illness and insanity. At the same time, there is also a good yellow: gold, honey and ripe ears — a sign of power, joy, abundance. The book is dedicated to these and other semantic metamorphoses of yellow. Michel Pastoureau is a Medieval historian, professor at the Practical School of Higher Studies in Paris.
