It contains a double ending for the Gospel of Mark. Textual critic F.H.A. Scrivener described it as 'by far the most remarkable document of its age and class' despite noting it was 'carelessly written by an ignorant scribe'.

Codex Basilensis is probably the oldest manuscript containing an almost complete text of the Gospels. Three of its leaves are palimpsests that were overwritten by a later hand, and it features early systems of dividing the gospels into referential sections.
