The First Continuation added 9,500 to 19,600 lines (depending on the manuscripts) to the romance. It was once attributed to Wauchier de Denain, and is sometimes called the Pseudo-Wauchier Continuation for that reason. It exists in a short, a mixed, and a long version; the short was the earliest and the most loosely linked to Chrétien's work, while the mixed is considered to be the latest, drawing on both earlier versions. Roger Sherman Loomis believed that the short version, which was added to an existing "Perceval" manuscript ten or twenty years later, represents a version of the story that was originally independent of Chrétien's.
