GA 473 is the same manuscript that was known to F. H. A. Scrivener in 1853 as Lambeth Palace MS 1178 when he collated it (as Gospels-MS “d”) for his book about A Full and Exact Collation of About Twenty Greek Manuscripts of the Holy Gospels.
“It is one of the most splendid manuscripts extant,” Scrivener wrote about GA 473. He also mentioned that GA 473’s text “contains many remarkable variations, such as Scholz would refer to his Alexandrian recension.” Robert Waltz has briefly updated Scrivener, noting that GA 473 is part of von Soden’s “family IKC,” and thus an imperfect representative of Family Π, which constitutes, for the most part, the earliest stratum of the Byzantine Text of the Gospels.
Scrivener listed 32 notable unusual readings attested by GA 473. Because he collated the entire text, there is no need to go through them all here, but a few may be pointed out as examples:
At Matthew 23:27, GA 473 reads
τοῖς ἀνθρώποις after φαίνονται, a reading shared by F and 33 (sorta).
At Mark 16:19, GA 473 reads ἐν δεξια instead of ἐκ δεξιῶν, a reading shared by C and Δ.
At Luke 14:32, GA 473 reads εις before πρεσβείαν, yielding a minor tweak of the meaning.
At Luke 17:17, GA 473 reads ευκοποτερον (relieved) instead of the usual εκαθαρίσθησαν (cleansed). Perhaps an overly scrupulous scribe did not think that those who did not express thanks for the miraculous healing Jesus had given merited being called clean.
At John 2:14, GA 473 is missing the words καὶ περιστερὰς (and doves). This was very extremely probably due to simple parablepsis from the καὶ before περιστερὰς to the καὶ that comes after περιστερὰς.At John 13:15, GA 473 reads ποιω instead of ἐποίησα.
At John 19:21, GA 473 is missing the first occurrence of τῶν Ἰουδαίων. This is probably not accidental, but a case of stylistic adjustment to remove perceived superfluity.
