Who is Virgil?

I think this is referring to the ancient Roman poet:

Then we bestrode our steeds and with his last adieu M.Fridrikssen treated me to a line of Virgil eminently applicable tosuch uncertain wanderers as we were likely to be: "Et quacumque viam dedent fortuna sequamur." "Therever fortune clears a way, Thither our ready footsteps stray."
