Reference to it has been made routinely throughout Western culture ever since its inception; two notable literary examples are Horace's ode 1.14 and "O Ship of State" by Henry Wadsworth Longfellow. Roger Williams, the founder of Rhode Island, used the metaphor in his "Letter to the Town of Providence" (1656). The Jacobins of the French Revolution frequently used this reference for the new French Republic as it defended itself from several European monarchies.
