"Ho, mia kor'" is considered to be the first literary text ever published in Esperanto. It is a short poem by L. L. Zamenhof, which was written a short time before he released Unua Libro (1887), in which it was published. In The Life of Zamenhof, Edmond Privat writes, "Zamenhof wrote at this time, very short verses. They sound much like the hard breathing of a person in a building, who runs to climb five flights of stairs and finally stops behind the door" (p. 35).

The iambic pentameter (and iambic dimeter) rhythm of this poem can be considered an illustration of its subject matter.
