314 ESTHETIC CONSIDERATIONS.

 which she appears only by way of simile, or comparison ; 

 the movement of the poem being meanwhile interrupted. 

 The most interesting of the latter class is to be found in 

 Shakspere's ' Venus and Adonis/ a piece in which the

But after taking this hurried glance from the summit
