Why Spenser is Called "The Poet’s Poet”?

Spenser as "The Poet’s Poet":

It was Charles lamb who called Spenser “the poet’s poet” and lamb was not wrong in giving him that honored title. Spenser is regarded as the poet’s poet and the second father of English poetry and Chaucer is the first. The poetic faculty in Spenser is so abundantly and predominantly present that we cannot think of any other poet without Spenser to occupy the pride of place among English poets.
