Agripina Casimira de los Dolores Samper Agudelo[1] (4 March 1833 — 22 April 1892)[2] was a Colombian poet. Having a literary family, she received an education not easily accessible to women of her time and country. She wrote prose and poetry under the pseudonym "Pía-Rigán", an anagram of her given name. Her work remained unpublished during her lifetime and was only anthologized and published posthumously.
Born Agripina Casimira de los Dolores on 4 March 1833 in the city of Honda, then part of the Department of Cundinamarca, her parents were José María Samper Blanco and María Tomasa Agudelo y Tafur,[2] she was their only daughter and seventh out of the eight children born to José María and María Tomasa.[1] Two of her siblings stand out: José María, who married Soledad Acosta Kemble, both were writers and journalists in their own right; and Miguel, writer and prominent politician. On 4 July 1857 she married Manuel Ancízar Basterra, a scientist and writer, and out this marriage were born Roberto, Pablo, Inés, Jorge, and Manuel.[3] When she widowed in 1882, she moved with her children to Paris, where she died on 22 April 1892.[1]
