Latin octosyllabic poem by Aldhelm, in which he describes a terrific storm that raged as he passed through Cornwall (Cornubia) on his way to Devon (Domnonia). It is addressed to a certain Lector, casses catholice / atque obses anthletice. The use of casses (helmet) and obses (hostage) has been interpreted as a reference to someone named Helmgisl. Lapidge suggests that Helmgisl may perhaps be identified with Hæmgisl, first abbot of Glastonbury.

Elaborate diagram of the ‘harmony of the months and elements’, which once occupied a single page in a largely computistical manuscript compiled by Byrhtferth of Ramsey (c. 970–c. 1020). The original of this compilation is lost, but two independent ‘copies’ made in the early 12th century remain. The diagram aligns different aspects of time (solstice, equinox, months, seasons, ages of man), the zodiac and the four elements, and in this way, introduces a number of key concepts relevant to computus. In the Oxford manuscript, the diagram comes right at the end of a section (ff. 3r-7v) which contains a miscellaneous variety of short texts and visual designs related to computus, and directly precedes another section (ff. 8r-15v) containing tables and texts on computus.

Encyclopaedic work written by the English jurist and cleric Gervase of Tilbury. It was dedicated to Emperor Otto IV and intended for his instruction and entertainment, although it is unclear if he ever heard or read the work. The work is divided into three books or decisiones: book I covers the early history of the world, from Creation onwards; book II offers a historical geography of the world (mappa mundi) and its provinces, with excursions on the Holy Land and the six ages of the world. While anecdotal material, including legends about marvels (mirabilia), is found throughout the first two books, book III is entirely devoted to marvellous phenomena.
