In the daily newspaper "El Constitucional" (Barcelona) July 3, 1841 page 4 and in the daily "El Guardia nacional" (Barcelona) July 3, 1841 page 4 as well, is the listing of the concert at the Teatro Nuevo on Saturday July 3, 1841, where we see the Classical Guitarist, Buenaventura Bassols (1812-1868), using the Tripodion, invented by his colleague and friend, Dionisio Aguado, in concert. He played the "Fantasia for Guitar over the theme from Semiramis", in the first part of the program.
The text indicating this usage is: "Fantasía de Guitarra sobre un
tema de la Semiramís ejecutada por Buenaventura
Bassols que tocará sobre el pie inventado por el celebre
Guitarrista Dionisio Aguado."
These Tripodions had been available for purchase in Madrid since 1838, see the other historical article on the subject, with the prices.
In the sketch of Dionisio Aguado, we see him holding a guitar made in Paris by Etienne Laprevotte. We sold one made in 1839 over a year ago.
The other photo shows the cover of the 1843 method book.
