For a charmingly naive example of the primers referred to, see the little Anglo-Saxon manual of astronomy, sometimes attributed to Aelfric; it is in the vernacular, but is translated in Wright's Popular Treatises on Science during the Middle Ages.

Bede is, of course, its chief source.

For Honorius, see De imagine mundi and Hexaemeron (Migne, Patr.Lat., vol.clxxii).

The De philosophia mundi, the most rational of all, is, however, believed by modern scholars to be unjustly ascribed to him.

See note above.
The strength of this current which overwhelmed the thought of Honorius is seen again in the work of the Dominican monk, John of San Geminiano, who in the thirteenth century gave forth his Summa de Exemplis for the use of preachers in his order.
