The Aeneid
From Memory Alpha, the free Star Trek reference.
The Aeneid is an epic poem written by the Roman poet Virgil that tells the story of the Trojan Aeneas who traveled to Italy to become the forefather of the Roman people.
In the mid-22nd century, a quote from The Aeneid, "audentes fortuna juvat" appeared on the Columbia's dedication plaque. (ENT: "Home", "Affliction" set artwork) Translated into the English language as "Fortune favors the bold," this quote has become an Earth proverb.
Prior to traveling back in time to the 20th century aboard the HMS Bounty, James T. Kirk cited a variation of this quote to himself, stating "May fortune favor the foolish," moments before giving the order to engage the slingshot effect. (Star Trek IV: The Voyage Home)
The saying was also cited by Benjamin Sisko when he launched his assault to recapture Deep Space 9 in early 2374. (DS9: "Favor the Bold")
Leonard McCoy paraphrased The Aeneid when he brought birthday presents (including Romulan ale) to Kirk, announcing "beware Romulans bearing gifts." (Star Trek II: The Wrath of Khan)
