Gutta cavat lapidem is found in Ovid's Epistulae ex Ponto (IV.x.5): gutta cavat lapidem, non vi sed saepe cadendo (the drop hollows the stone, not by force but by falling often). Students should note the crucial addition non vi sed saepe cadendo (not by force but by falling often): the drop does not hollow the stone by being harder or more powerful than the stone but purely through persistence and repetition. This is a fundamentally different model of achievement from that of aut Caesar aut nihil: it is not about intensity, genius, or overwhelming force but about patience, regularity, and the accumulation of small efforts. For poetry students, this is an important principle of the writing life: the poem that is worked on every day, however briefly, will eventually be finished; the grand gesture of writing only when inspiration strikes may produce nothing. The phrase is also found in a similar form in
Lucretius's De Rerum Natura. Related terms include perseverantia (perseverance), labor (work), and the concept of the via negativa applied to creative practice.
