One must strike the iron while it is hot. Opportunities must be seized at the right moment, when conditions are favorable, before the chance cools and becomes impossible to act upon. Hesitation at the crucial moment wastes the opportunity entirely.
The smithy was one of the most important and universal of medieval trades, and the blacksmith's daily reality gave Italian folk wisdom one of its most durable metaphors. Iron must be heated to a specific temperature — glowing orange or yellow — before it can be shaped; a moment too soon or too late and the blow of the hammer either does nothing or breaks the metal. Every smith knew that working the iron was a matter of precise timing, and that hesitation was costly in fuel, time, and wasted effort. The metaphor transferred naturally to human affairs: military commanders knew that a retreating enemy must be pursued immediately; merchants knew that a willing buyer could change his mind overnight; lawyers knew that a favorable judge might be replaced; lovers knew that the moment of mutual openness was brief. The proverb was documented in Italian collections from the 15th century and was widely used by Renaissance humanists in political writing, advising princes and condottieri to exploit favorable moments. Machiavelli's analysis of political opportunity (virtù and fortuna) is a sophisticated philosophical elaboration of the same basic insight.
Documented in Italian collections from the 15th century; related to classical Latin equivalents; the smithing metaphor was universal in pre-industrial European culture.
