While her racked soul repose and peace requires,
The fierce Thalestris fans the rising fires.

And continued at the 94th verse of this Canto.—Pope.

[459] Garth in the Dispensary, canto iv.:

The bat with sooty wings flits through the grove.

[460] Spleen was thought to be engendered by the east wind. Cowper, in the Task, Bk. iv. ver. 363, speaks of

the unhealthful east
That breathes the spleen.

[461] In this description our poet seems to have had before him the Cave of Envy in Ovid, Met. ii. 760:

Protinus Invidiæ nigro squallentia tabo
Tecta petit. Domus est imis in vallibus antri
Abdita, sole carens, non ulli pervia vento.

Shut from the winds and from the wholesome skies,
In a deep vale the gloomy dungeon lies;
Dismal and cold, where not a beam of light
Invades the winter, or disturbs the night. Addison's Trans.— Wakefield.

[462] For "Megrim," the first edition has "Languor."
