Galician Letters Day

Today, May 17th, is "Galician Literature Day" or "Galician Letters Day". It's a day of celebration around the Galician language and its literature.
The first celebration took place in 1963 to commemorate the centenary of Cantares gallegos, the first work written in Galician language by Rosalía de Castro (1837–1885), who later became one of the most important poets in the history of Galicia. Cantares gallegos was first published on May 17, 1863.
Since 1963, each Galician Literature Day has been dedicated to a different writer in the Galician language. This writer must be dead, and is chosen by the Real Academia Galega (Royal Galician Academy).
This year is dedicated to Uxío Novoneyra, a poet from El Caurel, who died in 1999. He wrote many poems like the one in this video.
