The English king Georg III (1738-1820) was a dutiful sovereign, a loving family man, a good rider and sportsman, temperate in drink and food, refusing the orgies of his contemporaries. He patronized science and was a dedicated collector of book and pictures. In spite of his healthy living he four times after the age of 50 suffered from periods of illness, causing political crises. His symptoms were confusion, pains and discoloured urine. Each time he completely recovered after 3-4 months. These enigmatic fits have now been diagnosed as porphyria. Reference is given to the outstanding research by Swedish scientists regarding this disease.
英国国王乔治三世（1738 - 1820）是一位尽职的君主，一位慈爱的家庭成员，一名优秀的骑手和运动员，饮食节制，摒弃了同代人的放荡行为。他资助科学事业，是书籍和画作的热心收藏家。尽管生活健康，但他在50岁之后四次患病，引发了政治危机。他的症状包括神志不清、疼痛和尿液变色。每次他都在3至4个月后完全康复。这些神秘的发作现在已被诊断为卟啉症。文中提及了瑞典科学家关于这种疾病的杰出研究。
