El vibracionismo de Rafael Barradas: genealogía de un concepto
No full textVibrationism was an art movement developed by the painter Rafael Barradas (1890-1929) between 1917 and 1920, and this period remains one of the most recognized and recognizable of his artistic legacy. The aim of this paper is to look further into the concept of vibrationism in an attempt to reveal which elements of Barradas' artistic vision he sought to highlight by choosing this particular word. The author begins by addressing the frequent use of the concept of vibration in European avant-garde circles and then focuses on its emergence in Barradas' works from 1917 onwards. Finally, the meaning given to vibrationism in a text published by Torres- García is analyzed and his artistic interpretation of the style in his own paintings is discussed.El vibracionismo fue el movimiento pictórico practicado por el pintor Rafael Barradas (1890-1929) entre 1917 y 1920, y constituye una de las etapas artísticas más reconocidas y reconocibles de su trayectoría.

OS ESPELHOS DE BARRADAS DE CARVALHO: CRÔNICA POLÍTICA E HISTORIOGRAFIA DE UM EXILADO
No full textEste trabalho investiga a produção historiográfica e os artigos políticos do
historiador português Joaquim Barradas de Carvalho no período em que viveu no
Brasil na condição de exilado político (entre os anos de 1964 e 1970). O principal
objetivo é demonstrar que a produção acadêmica de Barradas é influenciada e
influencia sua visão política. O pesquisador e professor da USP é um espelho do
membro do Partido Comunista Português e opositor do Salazarismo – espelho que
reflete e, ao mesmo tempo, é refletido. Verificou-se que experiência de Barradas
enquanto exilado no Brasil tem uma importância fundamental na definição de suas
posições acadêmica e política (influindo tanto na imagem que traça do Regime
Salazarista como na sua própria auto-imagem enquanto intelectual). Procura-se,
também, entender a singular forma como o historiador caracteriza o período dos
Descobrimentos – entendido como auge da História Portuguesa, e centro em torno
do qual se organizam todos os outros períodos. Com esse objetivo analisam-se as
influências teóricas na obra de Barradas, especialmente a do discurso
decadentista – grupo de autores portugueses que tinham em comum uma
denúncia da decadência da sociedade lusitana relacionada a um sentimento de
saudade do seu passado glorioso. Por fim, constatou-se que essa visão histórica
de Barradas determina e é determinada pela sua oposição ao salazarismo
(entendido como verdadeira antítese da cultura dos Descobrimentos).This work investigates the historiographic production and
the political articles from the Portuguese historian
Joaquim Barradas de Carvalho in the period
that he lived in Brazil in exile (from 1964 to 1970). The
main goal is to show that Barrdas` academic production is
influenced and it also influences his political point
of view. The researcher and USP`s professor is a mirror
from the member of the Portuguese Communist Party and
opponent to Salazarism - mirror that reflects
and is reflected at the same time. It was noticed that
Barradas - experience as an exile in Brazil has a
fundamental importance on the definition of his academic and
political positions (influencing either on the image that
he creates of the Salazarist scheme or on his own auto-
image as an intellectual person). It is also sought to
understand the singular way the author characterizes the
discoveries period seen as the peak of the Portuguese
History, and the center in which all the other
periods are organized. With this objective, it is verified
the theoretical influences on Barradas` work, specially on
the decandestist speech group of Portuguese
authors that had in common a warning for the decadence of
the Portuguese society related to a saudade feeling from
its glorious past. Finally, it is noticed that this
Baradas` historical view determines and is determined by
his opposing to salazarism (seen as a truly antithesis from
the culture of the discoveries)
