Safe Luxury

Why so many archaic poems entitled "From The Vault" ?

Such as follow: from the vault: Ode on a Grecian Urn by John Keats; From the vault: The Quiet Life by Alexander Pope; From the vault: The Windhover by Gerard Manley Hopkins; from the vault: To His Coy Mistress by Andrew Marvell; Thanks in advance !

1. "from the vault" means that this piece is both historic and stored (i.e., vault) as treasured by mankind. It is not a part of the title, but instead is notating its source.
