This volume presents the four chapbooks published by Huidobro in 1917-18 and offers, at first glance, an odd mixture. Chronologically, we have El espejo de agua, written in Spanish in 1914-16, first published in 1916, but, to all intents and purposes not distributed until 1918, Ecuatorial (written in Spanish, although the author also made a French version, Equatoriale, which is believed to be later), Hallali and Tour Eiffel. These last two publications, composed in French, were both marked by textual experimentation and were important influences on the nascent wave of the Spanish avant-garde. The four chapbooks were bookended, so to speak, by the French-language volume Horizon carré (2017) and the Spanish-language collection, Poemas árticos (2018), both of which have already appeared in translation in this series of Huidobro volumes from Shearsman Books.
