Was Mary on the road to Emmaus?

No. The Gospel of Luke tells the story of two disciples who encounter the risen Jesus on their way from Jerusalem to Emmaus. We know the name of one of the disciples (Cleopas), while the other is unnamed. There’s no reason to believe that it was Mary, though, who would be unlikely to be making such a journey in the first place and who would surely have been identified by name if she had, given the prominence that she has elsewhere in Luke’s Gospel.
