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 archi tecture – 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 contempora ry art and architecture.
