The Golden Treasury of Scottish Poetry was edited by Hugh MacDiarmid, and published in 1940. From the introduction:
The difference … between this anthology and all previous anthologies of Scottish poetry — is that some little effort has been made to present an "all-in view" of Scottish poetry and in particular to give some little representation to its Gaelic and Latin elements.
It contained a number of ballads, and other anonymous verse. The introduction also makes the case for Lallans as a poetic language, contraEdwin Muir.
