We have some facts described in Gospels - First was St Mary Magdalene, then 12 Apostles, 2 other Disciples going from Jerusalem to Emmaus. But St Paul collected information about that facts together and added some, that are not written in Gospels: "He showed up to Peter, and the Twelve, and later 500 brothers together. Some of them live today, some died. Eventually he showed up to me" Authors of gospels didn't mention about those 500 disciples and about St Paul, because his conversion took place long after history in gospels ends* , but is described in their continuation - Acts of Apostles, chapter 9.
