    Is it probable that this depression has arisen from the distorting effect of some form of head dress, similar perhaps to that which is still applied to the heads of infants in various parts of France, as described by Drs. Foville and Lunier? This consists of a neckerchief passed twice round the head from the corona either to the back of the neck, when the resulting deformity (which is that of the Charlcombe skull) is designated annular by Dr. Gosse; or is carried under the chin and jaw, when it is termed bilobed by the same writer.

    The ophthalmic division supplies sensation from the eyebrows to the coronal suture. The sensory innervation stops at the corona, not at the hairline, and this fact may help one to differentiate a true abnormality from a factitious one, since people who are “faking” sensory loss more often lose sensation at the hairline.

  The sun and moon, when partially covered by light, fleecy clouds, are often seen encircled by one or more colored rings, which are called coronæ. […] In order to examine coronæ about the sun, it is best to view them by reflection from a blackened mirror, by which means the brilliancy of the sun's light is very much reduced. […] Coronæ are produced by the diffraction of the rays of light in their passage through the small intervals between the particles of condensed vapor in a cloud.

corona³

/kəˈɹəʊ.nə/

noun
plural coronas or corone
1. (poetry) A series of sonnets linked together such that the last word of each is the first word of the next.
  Quotations
  A favorite and most attractive combination is that of the corona or series of sonnets, employed to frame or develop some one theme. A list of these corone is given by Biadene, who selects and publishes from among them a series of three by Petrarch, and the famous corona of the months by Folgore da San Gemignano.

  But the poets of Siena, and particularly the Academy of the Intronati, found the proper way of constructing coronas—since the ones mentioned above should really be called sequences ['catene'] rather than coronas.
  1997, Michael R. G. Spiller, The Sonnet Sequence: A Study of Its Strategies (Studies in Literary Themes and Genres; 13), New York, N.Y.: Twayne Publishers, page 144
  [Lady Mary] Wroth alludes to these contexts as the corona of sonnets that crowns the sequence opens: "In this strang labourinth how shall I turne?" (Wroth, Poems 127).

  Both sets of echoes derive from the poets' first poems, and since first poems in Petrarchan sequences set stylistic, tonal, and thematic expectations, Robert [Sidney]'s double allusion to first poems should color readings of this, the first poem of his corona.
