Codex Sangermanensis designated by Dabs1 or 0319 (in the numbering Gregory-Aland), α 1027 (Soden), is a tenth-century diglot manuscript, formerly in the library of St. Germain des Prés, Paris, hence its name Sangermanensis, "of Saint Germanus".

It is particularly notable as one of the two such copies which display clear evidence of having had Claromontanus as exemplar (another is Uncial 0320).

[3][4] Because it is a diglot, Sangermanensis is also valuable for the study of the Latin bibles, namely the Vetus Latina.

[citation needed] The manuscript was examined and described by Bernard de Montfaucon, Johann Jakob Wettstein, Giuseppe Bianchini, and Johann Jakob Griesbach, who designated it by siglum E.[5] In 1805 it was collated by Matthaei.

The St. Germain Library suffered severely during the French Revolution, and Peter Dubrovsky, Secretary to the Russian Embassy at Paris, acquired this manuscript together with many other manuscripts stolen from the ecclesiastical libraries.
