The third book of the collection "Latin America: Thoughts" brings together texts written by Otavio Leonidio since 2005. Dispersed until now, the texts address three main themes: the thought and action of the great ideologist of Brazilian modern architecture – Lúcio Costa; the presence of Brazilian modern architecture in the contemporary production (here represented by the works of Angelo Bucci, Christian de Portzamparc, Álvaro Siza and Lelé); and, finally, the complex relation between contemporary art and architecture.
