yes
Title: Sara Teasdale

Title: Gormenghast (castle)
Passage: Gormenghast is a fictional castle of titanic proportions that features prominently in a series of fantasy works penned by Mervyn Peake.  It is the setting for the first two books in the Gormenghast series, "Titus Groan" and "Gormenghast".  It incorporates many of the elements of both medieval castles and Regency period stately homes, though in practice it operates like a small city-state.  It has its own government, a Byzantine system of laws and rituals, a rigid class system, and is seemingly self-sufficient.  The castle is home to the ancient House of Groan who have, as the Earls of Groan, ruled for centuries without anything changing.
Title: Mervyn Peake
Passage: Mervyn Laurence Peake (9 July 1911 – 17 November 1968) was an English writer, artist, poet, and illustrator.  He is best known for what are usually referred to as the "Gormenghast" books.  The three works were part of what Peake conceived as a lengthy cycle, the completion of which was prevented by his death.  They are sometimes compared to the work of his older contemporary J. R. R. Tolkien, but his surreal fiction was influenced by his early love for Charles Dickens and Robert Louis Stevenson rather than Tolkien's studies of mythology and philology.
