Nymph and Faun

Aine and Rosin try to replicate the restored Charles Hodge Mackie sculpture in the National Museum. Cian pointed out that the title was technically incorrect as Nymph is Greek and Faun is Roman, so it should be Nymph and Satyr. What sort of books is that boy reading? We only ever buy him the Beano annual and I can't recall the Bash Street Kids ever debating classical etymology
