[1] The title, which the book shares with the second poem, refers to Ballylee Castle, a Norman tower which Yeats purchased and restored in 1917.
[5] All of the poems included in The Tower had previously appeared elsewhere in print collections and periodicals.
The gold wood-cut style image depicts Thoor Ballylee and its reflection in waters below the tower all on a light green background.
The poet praised Moore's artwork, noting that the cover was both a true representation of Thoor Ballylee and a successful symbolic design for the collection.
Moore's work on The Tower and other collections solidified Yeats's modern image in both American and English print editions [8] Many of the poems in The Tower demonstrate Yeats's disillusionment with the limitations of the physical world and his withdrawal from ordinary life.
