   • 166 BCE, Publius Terentius Afer, Andria 907:

     CHREMĒS: Quid tū Athēnās īnsolēns? CRĪTŌ: Ēvenit.

     CHREMES: What [are] you [doing in] Athens, [since we’re so] unaccustomed [to seeing you here]?
     CRITO: It just happened [to turn out that way].
     (In context, Chremes is expressing his suspicions with dramatic irony, and Crito is hiding his true intentions. Cassell’s Latin Dictionary adds a word for clarification: Quid tu Athenas insolens venisti? — “What brings you to Athens so unexpectedly?” )
