shaft of the column arises. 6th, The a7ro$E<rK; S means a
icotia upright under the annulet in "which it terminates.
N. B. The apothesis is less than the apophygis, from whence
the shaft is gradually diminished : not indeed as some imagine
like the srustum of a cone, but in the most approved models
it exhibits a small swelling downwards. This is called by the
Greeks the entasis of the pillar, and may be most conveniently
described by the same instrument with which Nicomedes drew
the figure in geometry, called by him a conchoid.^
Of this class are thole channellings in the shaft of the co-
lumn, which are called by the several names of f stride,
striges, or as others name them from their shape, stri-
giles. For the sake of distinUion we will call those stride
which meet in an acute hollow, as T, and are twenty in,
number ; striges, which meet in an obtuse one, as V3
and are twenty four. These have also their swelling and di-
minution in proportion to that os the column. Sometimes
they are filled with a small twig, as it were, to the third part
of their height, as X, called by Aristotle Where-
fore a shaft of this kind we denominate a virgated one.
Some particles os an Order are formed with a waving ap-
pearance, i. e. convex and concave as the gsrmSij, Aumy,
xv/xa-not/,* sima upright and inverted, unda, cyma, cymatium,
Doric and Lesbian, which words writers varioully confound.
That we may form a distinct notion the larger undulated one
shall be called sima, or cyma, from its figure \ the less srom its
\ A name of a curve, which always approaches nearer to a sfcrait line to which
it inclines, but never meets it.
j- In this and some other instances the translator has been under the necessity
of retaining the Latin names, as he sinds none in English which will fully come
up to their meaning. Columns of this kind are ranked by the English Architects
under the. general name of fluted columns. See Baldi’s Lexicon Vitruvianum,
under the articles Striae and Striges.
* EjnnSiq, 'h-jo-ig, are synonimous words, saving the variation proceeding from
their situation. See Baldi’s Vitruvius, under the articles e7t;ti9a? and Xuiriq.
Cyma, cymatium and sima, signify a wave of a smaller or greater degree,
