There is an ancient greek inscription on page 467r which reads (translated by chat gpt)
"Whoever removes this present book from the place where the humble body of me, Theodosius the Prince, lies, let them be anathema, separated from the Father and the Son and the Holy Spirit, and may their portion be with Judas the betrayer."
which is presumably used to assert the ownership of the book by Theodosius of Prinkipos
There's also another inscription on page 3r which translates as
"And this [is] from Paisios, Bishop of Vothrotou and Glykeos, among others."
