Portrait of John George Robertson John George Robertson,  1911 Encyclopædia Britannica (1911)

“ Such are the decadent aspects of the once rich literature of the Middle High German period in the 14th and 15th centuries. Turning now to the more positive side of the literary movement, we have to note a revival of a popular lyric poetry—the Volkslied—which made the futility and artificiality of the Meistergesang more apparent. Never before or since has Germany been able to point to such a rich harvest of popular poetry as is to be seen in the Volkslieder of these two centuries. ”
