manuscript

The earliest known owner is the 16th century scholar Laurence Nowell, after whom the manuscript is named, though its official designation is Cotton Vitellius A.XV because it was one of Robert Bruce Cotton's holdings in the middle of the 17th century. Kevin Kiernan argues that Nowell most likely acquired it through William Cecil, 1st Baron Burghley in 1563, when Nowell entered Cecil’s household as a tutor to his ward, Edward de Vere, 17th Earl of Oxford.
