Introduction: Metaphysical poetry was firstly coined by the English writer Samuel Johnson basically to define lyric poets. John Donne and George Herbert are the important poets and pillars of the English literature in seventeenth century.Metaphysical poetry is a literary term coined by Samuel Johnson.It has its roots in 17th century England. Metaphysical poetry deals with the concept of love, faith, soul, death, and God. It uses arguments and logic instead of emotion or passion. This type of poetry deals with the psychological concepts of love, religion, and faith. Donne is called the chief of metaphysical poetry and his poetry is filled with metaphysical conceits as compare to George Herbert that is to a lesser extent as we can see the resemblance of George Herbert poem with donne’s poem it includes the similarities of common language in their poems in the rythms of speech for example the poems “ The Altar” and “Easter Wings” Their poetry was characterized by style, imagery, intellectual complexity and it is the blend of emotion that is charcaterized by wit. The comparative analysis of the poets John Donne and George Herbert will help us explore themes, use of metaphysical conceits, philosophical ideas, the use and concept of imagery, symbolism in poetic language. Major themes and concerns: Firstly, the poems of john Donne and George Herbert are different from one another as we see different themes in these poems. John Donne’s poem focuses on love themes such as a love of a beloved. The lovers are experiencing their love out of the world where no one can interfere or disturb their existence for example in the poem “ The sun rising” the speaker is against the sun rising on him and his beloved as he thinks that no one can disturb them not even the sun. The lovers are so in love that nothing else matters. Donne’s poem also addresses themes of death and faith that is reflecting the personal experiences. Where as the poem of George Herbert focuses on the themes of spirituality. His poems are often written for religious purposes involves the religious themes and practices. For example, in the poem Altar, the word Altar has been used as stone heart, representing the personal experiences and offerings of himself as a sacrifice to God and in the poem “The Priesthood” it describes the importance of holy men. It shows that how a priest is said to have direct contact with God describing the purity of priest. The writings of John Donne and George Herbert differs in a way that George Herbert accepted the concept that everything in nature is created in a simple way without questioning things and wrote the poetry that was simple according the previous rules while on the other hand we see the concept of John Donne was completely different he used to question things before writing he used to question things about humanity and nature he used to bring new theories and philosophies in his poems. Moreover, Donne sees death as defeat and challenge whereas Herbert view it as peaceful journey to God and the life hereafter. Use of metaphysical conceits: A metaphysical conceit is a generally a literary device such as metaphor and simile. It is used to analyze and describe the sensory information of the reader as it is used by the poets of 17nth century such as John Donne and George Herbert. Metaphysical conceits basically involve comparing things that are different from each other using various kinds of comparisons. Metaphysical poetry is a special branch of poetry that deals with an educational method and use of intellect and emotion in a peaceful manner. The most famous metaphysical poet was John Donne, he used to write about love, religion, and used to write new philosophical ideas. George Herbert was greatly affected by Donne. His work is marked by metaphysical conceits. In one of his poem “prayer” is called the spiritual feast. In George Herbert’s poem there are unique circular images the imperfect nature of love between human and divine God. While we see that John Donne poems are philosophical, reasoning, and logical. The use of metaphysical conceits are very common in John Donne’s poems and we find unique features of conceits in his poetry. Firstly, strange effect and new perspective in his poems, then we see common image, special kind of emotion. Some images can be found in the poetry but they are equipped with different colors of emotion. Donne plays an important and creative role in adding new meaning to the original image. For example, the sun as it brings light and heat to the earth and provide energy for the growth of living organisms but in his poem “ The sun rising” the sun has been declared as busy old fool and harsh sun. This shows that same sun has different meaning for the same word. The poem Flea by John Donne which is published in 1633 is a passionate metaphysical poem in which the concept of flea serves as an extended metaphor for the relationship between speaker and the beloved as in comparison the George Herbert’s poem, “The Altar” also published in 1633 illustrates the conceit of an Altar that how one should sacrifice himself to the lord. Both poets present the different ideas by using of poetic device as in the poem “ The Flea” the metaphysical conceits began when the poet say ‘And in his flea, our two bloods mingled be’. The metaphor suggests that the speaker believes the mixing of two bloods is similar to devotion of marriage. The speaker uses direct address when he says ‘how little that which thou deniest me’ here little word shows how he is trying to convince his lover. In contrast, the speaker in The Altar, is confused as Herbert refers a servant which shows that anybody could be speaking whether it is the poet, reader or anyone else. It is important that how John Donne and George Herbert have a distinct contrast in how they use religious as a theme to know the meaning of the poems.
