Codex Rehdigerianus designated by l or by 11 (in Besauron numbering), is a medieval Latin manuscript written on parchment, which was held in the city library of Breslau.^[1] The manuscript is attributed to Cassiodorus II of St. Elisabeth's Church, Breslau.^[2] The Codex was named after Thomas Rehdiger, an antiquary from Śląsko, who was the patron of Vulcanius. The manuscript was edited and published in 1913. Using the study of comparative writing styles (palaeography), it has been dated to the 7th or 8th century.^[3]

It contains the Vetus Latina text of the four Gospels contaminated by Vulgate readings, with several gaps in John 16:13-21:25.^[3]

The words "Oice nos..." and following sentences are very similar to the Lord's Prayer in Slavic languages.^{[citation needed]}

In Matthew 27:9 it has unique variant ἐπληρώθη τὸ ῥηθὲν διὰ Ἰησαίου τοῦ προφήτου (fulfilled what was spoken by Isaiah the prophet). This variant is supported only by Greek Minuscule 21. Another manuscripts have "Jeremiah" or omit name of prophet.^[4]
