Can you imagine what people once did for a living?From "walking toilets" to balladeers "who belted out the daily news," Rottmann covers dozens of professions that were once perhaps not popular but possible. Short entries ranging in length from one to three pages describe each profession and when and why it died out. Callouts illuminate noteworthy facts, provide historical or social context, or give more logistical details. Some jobs could be found in multiple cultures and countries; a few crossed gender lines. Some, like bematists (step counters who measured vast distances), disappeared due to advancements in technology and tools (hodometers in this case). Others went out of vogue with changing social, geological, or political dynamics: "What people find useful is always changing. So, certain professions disappear, but new ones come into being." Alchemists fell out of favor, superseded by chemists; natural historians, biologists, archaeologists, and professional treasure hunters are modern-day explorers. Rottmann notes that some jobs, such as professional mourners, might be making a comeback. Bold, almost caricature-esque, cartoony illustrations capture the gamut of professions featured in this Swiss import, from the bleak, beak-wearing plague doctor to the showy festival pyrobolists. Occasional anecdotes provide wry commentary-alchemists brewed Qin Shi Huang, the first emperor of China, an elixir of life only to accidentally kill him with poisonous mercury.
