"Baile en Tehuantepec". By Diego Rivera, 1935.

There is a poetry that I really like, It is titled "Diidxazá" written by Gabriel López Chiñas.

Diidxazá

Naacabe 'ma chee diidxazá,

guiruti ma 'Zani' la ';

ma birábilushe naacabe '

diidxa 'Guni binnizá.

Diidxa 'Guni binnizá,

binidxaba the zine '

yanna ca binni nuu xpiaani '

Güirá 'hriní' diidxaxtiá.

Ay !, diidxazá, diidxazá,

ca or bidiideche lii,

qui gannadica 'Fabia'

nñaaca 'gunashiica' lii.

Ay !, diidxazá, diidxazá,

diidxa 'hrusibani na'

na 'nanna zanitilu'

dxi initi gubidxaca '.

Zapotec
People say that Zapotec is dying,

and no one will speak it;

It is already finished, people say,

the language of their ancestors.

  

The language of the Zapotecs,

it will be taken by the evil,

Now the educated people

all speak Spanish.

  

Ay !, Zapotec, Zapotec,

those who gave the back to you,

do not know how

their mothers loved to you.

  

Ay !, Zapotec Zapotec,

language that revives me,

I know you will you die,

the day that the sun dies.
