you missed one key word: “during” Her Assumption.
She died during her assumption?
That would be awkward to depict on an icon. I’m thinking of popular UFO images with the limp body being sucked into the green light.
Instead, we celebrate her Dormition, or falling asleep. It is so important that it is one of the strictest fasts in the east, lasting two weeks before the feast day. The term falling asleep is consistently used throughout the Bible to emphasize that a physical death is not the end, but the beginning of life everlasting. Every use of it refers to a physical death, just as it does with Mary’s. That’s why the icon of the Dormition has her lying on a funeral bier, being carried through the streets for her funeral, with all the apostles (minus Thomas) mourning her death.
In front of her funeral bier, we see an angel chopping off Jephonius’ hand. He was a Jewish priest who was trying to disrupt the funeral procession as they took Mary’s body to the Garden of Gethsemane to be buried. Jephonius repented and his hand was restored.
Behind, we see Mary’s soul, wrapped in a burial shroud, being “born” into eternal life and being received by Jesus into heaven.
Mary was buried in the Garden along with her parents, Saints Joachim and Anna, and with St. Joseph. St. Thomas, ever late, came three days later. He was so sad that he had missed her funeral that the other apostles opened the tomb to allow St. Thomas to say goodbye and to venerate her body. When they opened the tomb, she was not there and only a small piece of the burial shroud remained. Later that night, Mary appeared to them in her heavenly glory and told them, “Rejoice! I am with you always and will pray for you before God.” The apostles responded to her by saying, “Most-holy Mother of God, help us!” Some icons show Mary crowned in heaven to depict this scene as well.
