About the Hippocratic Oath, as quoted in “I do solemnly swear . . .,” “first, do not harm” is not in it, although it has been said so dozens of times. Dorland’s Illustrated Medical Dictionary‘s version of the oath states “. . . never do harm to anyone.” “First, do no harm” (Primum non nocere) has been attributed to Galen, who practiced 550 to 600 years later than Hippocrates.
