[13.] "Power of harmony to calm the turbulent sallies of the soul. The thoughts are borrowed from the first Pythian of Pindar" (Gray).

[14.] Solemn-breathing airs. Cf. Comus, 555: "a soft and solemn-breathing sound."

[15.] Enchanting shell. That is, lyre; alluding to the myth of the origin of the instrument, which Mercury was said to have made from the shell of a tortoise. Cf. Collins, Passions, 3: "The Passions oft, to hear her shell," etc.

[17.] On Thracia's hills. Thrace was one of the chief seats of the worship of Mars. Cf. Ovid, Ars Am. ii. 588: "Mars Thracen occupat." See also Virgil, Æn. iii. 35, etc.

[19.] His thirsty lance. Cf. Spenser, F. Q. i. 5, 15: "his thristy [thirsty] blade."

[20.] Gray says, "This is a weak imitation of some beautiful lines in the same ode;" that is, in "the first Pythian of Pindar," referred to in the note on 13. The passage is an address to the lyre, and is translated by Wakefield thus:

"On Jove's imperial rod the king of birds
Drops down his flagging wings; thy thrilling sounds
Soothe his fierce beak, and pour a sable cloud
Of slumber on his eyelids: up he lifts
His flexile back, shot by thy piercing darts.
Mars smooths his rugged brow, and nerveless drops
His lance, relenting at the choral song."
