Warton says that `John Some and Nicholas Lynne' were both Carmelite friars, and wrote calendars constructed for the meridian of Oxford.  He adds that Nicholas Lynne is said to have made several voyages to the most northerly parts of the world, charts of which he presented to Edward III.  These charts are, however, lost.  See Hakluyt's Voyages, i. 121, ed. 1598; Warton, Hist. E. P. ii. 357; ed. 1871.

Tyrwhitt, in his Glossary to Chaucer, s. v. Somer, has the following.  `The Kalendar of John Somer is extant in MS. Cotton, Vesp. E. vii.  It is calculated for 140 years from 1367, the year of the birth of Richard II, and is said, in the introduction, to have been published in 1380, at the instance of Joan, mother to the king.  The Kalendar of Nicholas Lenne, or Lynne, was calculated for 76 years from 1387.  Tanner in v. Nicolaus Linensis.  The story there quoted from Hakluit of a voyage made by this Nicholas in 1360 ad insulas septentrionales antehac Europæis incognitas, and of a book written by him to describe these countries a gradu .54. usque ad polum, is a mere fable: as appears from the very authorities which Hakluit has produced in support of it.'  It seems probable, therefore, that the `charts' which Warton says are `lost' were never in existence at all.  The false spelling `Some' no doubt arose from neglecting the curl of contraction in Somere.
