Asterix Conquers Rome (French: Les 12 Travaux d'Asterix, literally "The 12 Tasks of Asterix"), first published in 1976, is the comic book adaptation of the animated Asterix film The Twelve Tasks of Asterix and "unofficially" the twenty-third Asterix volume to be published. The comic follows the movie very exactly. It has very rarely been printed and is not widely known even amongst Asterix fans. The English translation has only been printed as part of a one-off comic book annual, the Asterix Annual 1980. It is thus often excluded from "canonical" lists of Asterix volumes with the subsequently published Obelix and Co. typically being listed as the "official" twenty-third volume. An unauthorized English language digital edition in CBR format, titled The Twelve Tasks of Asterix, is also known to exist. Source: Wikipedia (en)
