Abstract
Aloe vera is a popular herbal product and its extracts are part of a multi-million-dollar (US) industry. Aloes have been used as a remedy worldwide for centuries. To elucidate the accumulation of knowledge from the Greco-Roman period to the Renaissance, we have sought the earliest surviving illustrations and preserved herbarium specimens of flowering Aloe. This search for illustrations of Aloe vera in Medieval manuscripts and early printed books up to 1590 shows that most of these sources depict and describe only vegetative material. The first illustration we identified of an unambiguously flowering Aloe vera is from an Arabic manuscript dated to the 12th century. The first printed illustration of a flowering plant appeared in 1562 and is based on paintings executed no later than around 1560. The earliest records of flowering Aloe vera are provided by Italian herbarium specimens from the period 1539–1554, but Aloe was successfully cultivated in Italy (Venice) as early as around 1445–1448, and in Germany (Nürnberg) in 1542.
