Most scholarship places the poem’s composition somewhere in the early medieval period (often broadly c. 700–1000), reflecting its mix of Germanic heroic legend and Christian framing; the precise date remains debated.
The sole surviving manuscript of Beowulf (in the Nowell Codex portion of Cotton MS Vitellius A XV) was copied around the turn of the first millennium, in two scribal hands that divide at about line 1939 of the poem.
The Nowell Codex assembles Beowulf alongside related Old English prose/poetic works (e.g., Life of St Christopher, Wonders of the East, Letter of Alexander to Aristotle, and Judith), indicating an anthology interest in marvels, monsters, and heroic narrative.
Antiquary Laurence Nowell owned the manuscript in the mid-16th century and left a notable ownership mark by inscribing his name (often associated with the year 1563), giving rise to the modern nickname “Nowell Codex.”
At some point (in early modern collecting), the Nowell Codex was bound together with the separate “Southwick Codex” (a 12th-century Old English prose manuscript), creating the composite volume now known as Cotton MS Vitellius A XV.
The volume was acquired for the Cotton library (assembled by Sir Robert Bruce Cotton) and shelved under the distinctive Cotton pressmark system, becoming known as Cotton Vitellius A XV.
The Cotton manuscript collection (including Vitellius A XV) was effectively donated to the public, marking a major step toward national stewardship of the Beowulf manuscript.
Humfrey Wanley’s 1705 catalogue (published within George Hickes’s Thesaurus) includes the earliest well-known scholarly notice describing the poem in Vitellius A XV and excerpting lines—an important moment in Beowulf’s “rediscovery.”
A fire at Ashburnham House (where Cotton manuscripts were stored) singed and damaged Vitellius A XV, accelerating later edge-loss and illegibility; the event became central to the manuscript’s conservation and textual history.
Under the Act establishing the British Museum, the Cotton library became one of its foundation collections, institutionalizing curatorial access to Vitellius A XV for scholarship.
Grímur Jónsson Thorkelin arranged two complete transcripts (now in Copenhagen), which later proved crucial because they preserve readings subsequently lost or obscured in the fire-damaged manuscript.
A major printed catalogue of the Cottonian manuscripts (prepared at the British Museum) was issued in 1802, aiding systematic identification and access to items like Vitellius A XV.
Thorkelin published the editio princeps (first printed edition) of Beowulf in Copenhagen, enabling wider philological scrutiny beyond manuscript consultation.
To slow ongoing deterioration after the 1731 damage, the manuscript’s leaves were mounted in paper frames (a 19th-century conservation intervention), helping preserve the physical book while also affecting visibility of some margins.
