Here we will note a couple of comments about the mss as well.
... two new attestations (add it to the long list) for the "Long Ending of Mark" :
Palladius of Ratiara (4th century) and Romanos the Melodist (6th century)
PALLADIUS : he says that in the gospel of Mark it is written (so and so from the long ending)
ROMANOS : In his hymn for the mission of the apostles, he uses the same wording of Mark 16.15 "poreuthentes eis panta ton kosmon" / "poreuthentes eis ton kosmon hapanta"
