Virent Ova! Virent Perna! is otherwise known as Green Eggs and Ham in Latin.
Whilst Green Eggs and Ham is certainly a lot more than just a fun book, it is funny to see it appear in such a scholarly language in Latin, which, of course, is no longer spoken by anyone as a first language.
I imagine that Virent Ova! Virent Perna! would make an interesting and amusing interlude for any youngsters at a school where Latin is still taught.
For the non Latin-learners amongst us we will have to do with the original English version of Green Eggs and Ham, or, take a look at one of the other translations of the book which include Spanish, French and Hebrew: Green Eggs and Ham in 8 Languages.
