See headnote to No. 68. Almost all Gill's examples, as he himself says (p. 97), are taken from Spenser's Faerie Queene. The two below are a little less specific than most.
(a) From Logonomia Anglica (1621), p. 99; repr. in edition of O.L. Jiriczek (Strasburg, 1903), pp. 104-5:
[Gill is talking about metaphor.] From this source, rise all allegories and similes (also most proverbs and enigmas). For allegory is nothing but a continued metaphor….
[quotes Faerie Queene III. iv. 8-91−3]
But all Spenser's poem is an allegory, by means of which he educates his readers morally with fables. Thus allegory, working like a metaphor, deals darkly with a whole world…. Proverb and enigma deal with it more obscurely yet. Simile operates more clearly, because the metaphor is first of all unfolded, and then set alongside its actual reference.
[quotes Faerie Queene I. ii. 161−7] 1
(b) Ibid., p. 142; repr. Jiriczek, p. 146:
In Spenser's Epic or Heroic Poem, every ninth verse, for the sake of its weight and a certain sureness of stance, is a hexameter. 2
1Ab hoc fonte Allegoriae omnes, & Comparationes,etiam pleraeque; et'. Allegoria nihil enim est, quam continuata Metaphora…. Sed & totum Spenseri poema allegoria est, qua ethicen fabulis edocet. Sic Allegoria rem totam per Metaphoram obscure tractât: Paroimia & Aenigma multo obscurius: Comparatio dilucidius, quia primo Metaforam explicat, postea cum re componit.
2Spenceri tamen Epicum, siue Heroicum, nonum quemque versum habet hexametrum; ad grauitatem, & quandam stationis firmitudinem.
