Fly, envious Time, till thou run out thy race,
Call on the lazy leaden-stepping hours,
Whose speed is but the heavy plummet's pace;
And glut thyself with what thy womb devours,
Which is no more than what is false and vain,
And merely mortal dross;
So little is our loss,
So little is thy gain.
For when as each thing bad thou hast intombed,
And last of all thy greedy self consumed,
Then long Eternity shall greet our bliss
With an individual kiss,
And Joy shall overtake us as a flood;
When every thing that is sincerely good
And perfectly divine,
With truth, and peace, and love, shall ever shine
About the supreme throne
Of Him, t' whose happy-making sight alone
When once our heav'nly-guided soul shall climb,
Then, all this earthly grossness quit,
Attired with stars, we shall for ever sit,
Triumphing over Death, and Chance, and thee, O Time. 

John Milton

        On Time,” by the English poet John Milton 1608-1674, deals with one of the most common themes in all of medieval or Renaissance literature: the theme of mutability, or the idea that life on earth is full of constant and mainly negative change. The inevitable passage of time was a particularly painful example of such change, especially since it ultimately involved physical deterioration and then, eventually, physical death. Milton’s poem is a response to such gradual but certain decay. Like many other writers of his era an era dominated by Christian thinking, Milton emphasized that humans can escape the ravages of time by attaining an eternal life in heaven that is full of joy.Line 1 begins with the vigorous verb “Fly” that is, “flee”, which immediately asserts the speaker’s vigor and self-confidence. Rather than being intimidated by time, he attacks and mocks it. Time is “envious,” a word which in Milton’s era mainly meant being hateful, malignant, and/or spiteful. But perhaps it also here suggests that Time, which is limited and bound to end, envies human beings, who are capable of existing eternally. In any case, by personifying time as “Time,” Milton makes it almost seem a living thing an assertion which already implies a bit of irony since he soon suggests that Time will die. Time, in this poem, seems not merely an abstract philosophical concept; it is a malevolent, active being whom one must resist and defeat. The speaker, however, immediately implies that he feels no fear of Time; from the very first line, he suggests that Time is fated to suffer death.Line 2 shows Milton’s talent for using sound effects. In this case, the effects involve not only  alliteration (repetition of similar consonant sounds) but also assonance (repetition of similar vowel sounds), as in the repetition here of “l’s” and short “e’s”: “Call on the lazy leaden-stepping hours.” Having already mentioned the word “race” in line 1 (a word implying speed), the speaker now implies (through the use of the particular adjectives here) that Time moves very slowly. It is as if the speaker feels contempt for the “lazy leaden-stepping hours,” as if he is almost eager for Time to run its race as quickly as possible.
