Tirso de Olazábal appears in the Fifth Series (Spain Without a King) of Benito Pérez Galdós's Episodios Nacionales.
It is also possible that Olazábal has also been acknowledged in world literature; the 1919 novel of Joseph Conrad, The Arrow of Gold, features a person referred to as "Lord X", whose activities as arms smuggler resemble those of Olazábal [REF].
