 Catullus 2 and 2b differ significantly in their tone and subject.Catullus 2 is addressed directly to the bird ("with you") and describes its loving, playful relationship with the poet's girlfriend.By contrast, Catullus 2b mentions neither bird nor girlfriend, introducing a simile to the story of Atalanta, and seems to be written in the third person ("it is as welcome to me"), although some scholars have suggested that the text was corrupted from the second person ("you are as welcome to me").
