Gower was largely a religious court poet, his poems formed for recitation. Whether in Latin, French, or English, the poems are generally highly allegorical. Gower describes; he doesn't innovate - save for the first major use of English in poetry.
His most famous poem is The Lover's Confession, dignified in Latin as Confessio Amantis. For this poem, Gower was heavily influenced by Jean de Meun's Romance of the Rose.
Gower was born of a prominent and well-off family; his was a rich lifestyle from birth. There is some evidence for a strong friendship between Gower and Chaucer; for a time, they swapped dedications of new poems.
