However, it is not the old Mass, as Gänswein calls it. The first Mass was the Last Supper, and I previously traced the roots of the form before all the changes to A.D. 199 (Pope St. Victor 1). That made the Mass timeless and continuous until Vatican II severely damaged those roots.
P.S. I learned today that my brilliant student, age 9, has read H.P. Lovecraft (1890-1937), author of fiction classified as weird, science, fantasy, and horror. I said, "You never told me that." His answer, "You never asked." A couple of Lovecraft's narrated short stories are in the English category.
