Which period is associated with challenging Galen's authority?

• A. The Medical Renaissance
• B. The Classical Era
• C. The Industrial Revolution
• D. The Enlightenment

Answer: (D)

The move away from Galen’s authority began with a revival of careful, evidence-based study of the human body. In the Medical Renaissance, scholars returned to direct observation and dissected human bodies to check old texts. A turning point was Vesalius’s work, De humani corporis fabrica, which laid out accurate human anatomy and showed where Galen’s descriptions, based on animal dissections, were incorrect. Later, Harvey’s findings on blood circulation further challenged Galen’s humoral theory. While the Enlightenment promotes questioning authorities more broadly, the specific challenge to Galen’s authority starts in the Medical Renaissance. The other periods don’t fit as well: the Classical Era is too early, the Industrial Revolution centers on industry, and the Enlightenment comes after the initial medical shift.
