I want to know the answer to the following question:
Which short narrative poem was attributed to Virgil as early as the 1st century AD?
All the background I'm provided with is that "One, the Catalepton, consists of fourteen short poems, some of which may be Virgil's, and another, a short narrative poem titled the Culex ("The Gnat"), was attributed to Virgil as early as the 1st century AD.". Is that enough to answer the question?
Answer: yes
