  The canonical gospels are four accounts, each by a different author. The authors of the Gospels are pseudonymous, attributed by tradition to the four evangelists, each with close ties to Jesus: Mark by John Mark, an associate of Peter; Matthew by one of Jesus's disciples; Luke by a companion of Paul mentioned in a few epistles; and John by another of Jesus's disciples, the " beloved disciple ".
  
  According to the Marcan priority, the first to be written was the Gospel of Mark (written AD 60–75), followed by the Gospel of Matthew (AD 65–85), the Gospel of Luke (AD 65–95), and the Gospel of John (AD 75–100). Most scholars agree that the authors of Matthew and Luke used Mark as a source for their gospels. Since Matthew and Luke also share some content not found in Mark, many scholars assume that they used another source (commonly called the " Q source ") in addition to Mark.
  
  One important aspect of the study of the Gospels is the literary genre under which they fall. Genre "is a key convention guiding both the composition and the interpretation of writings". Whether the gospel authors set out to write novels, myths, histories, or biographies has a tremendous impact on how they ought to be interpreted. Some recent studies suggest that the genre of the Gospels ought to be situated within the realm of ancient biography. Although not without critics, the position that the Gospels are a type of ancient biography is the consensus among scholars today.
  
  Concerning the accuracy of the accounts, viewpoints run the gamut from considering them inerrant descriptions of Jesus's life, to doubting whether they are historically reliable on a number of points, to considering them to provide very little historical information about his life beyond the basics. According to a broad scholarly consensus, the Synoptic Gospels (the first three—Matthew, Mark, and Luke) are the most reliable sources of information about Jesus.
