Perfume begins in smoke-and then refuses to stay put. From Egypt's kyphi and Mesopotamian resins to Greek oils, Roman spectacle, Hebrew anointing, Islamic distillation, Renaissance intrigue, Versailles excess, modern chemistry, and today's clone culture and fragrance influencers, The Scent of Time traces how smell has steered religion, medicine, politics, trade, and desire. D. M. Gross moves era by era across the globe-India's attars and Ayurveda, China's incense philosophies, Japan's kodo, the Middle Eastern oud tradition, the rise of Grasse and French houses, and the 20th-21st century boom-revealing the economies, empires, and everyday lives built on invisible plumes. The result is a page-turning cultural history that treats perfume not as vanity, but as a force. If you've ever chased a memory through a scent trail, this book explains why-and how humanity has bottled its ambitions for 5,000 years.
