The "Divine Comedy" is composed of 14,233 lines that are divided into three "cantiche" (singular "cantica") – "Inferno" (Hell), "Purgatorio" (Purgatory), and "Paradiso" (Paradise) – each consisting of 33 cantos (Italian plural "canti"). An initial canto, serving as an introduction to the poem and generally considered to be part of the first "cantica", brings the total number of cantos to 100. It is generally accepted, however, that the first two cantos serve as a unitary prologue to the entire epic, and that the opening two cantos of each "cantica" serve as prologues to each of the three "cantiche".
