In the state of siege imposed by Argentina’s military government during
the latter part of the 1960's, Silo’s first attempt to speak publicly
was forbidden. When the authorities were consulted about whether Silo
could give the speech at a location far removed from any urban center,
they granted permission with the sarcastic remark that there was no ban
on “speaking to the stones.” And so on May 4, 1969, high in the Andes at
a place known as Punta de Vacas, Silo spoke before a small group that
had had to endure interrogation and harassment by armed security forces.
