Orthography of the mural paintings of San Miguel de Lillo

During the month of December 2014, we made the high-resolution orthographies of the mural painting of San Miguel de Lillo, to the Cultural Heritage Service of the Education Office of the Principality of Asturias.

The objective of this work was to create a documental basis of the current state in the shape of orthographies, which gives support to make previous studies and redacting the intervention project of the pre-Romanesque paintings that exist into the San Miguel de Lillo’s Church. It is important to remark that this project was made in coordination with Montserat Álvarez Fernández, restorer and responsible of the redaction of the intervention project of the paintings.

To the creation of the orthophotogrammetry we made a photogrammetric raising and a register of strengthen with a precision of +/- 5 mm, of the areas of concern of the temple which included fragment of the elevations of the south aisle ad the vaults of the south, north and centre aisle and lobby. Due to the space limitations, it was necessary to take more than 9000 photographs, to reach the wanted detail with a resolution of 1 mm per pixel, appropriate to its printing to real scale 1:5 with a resolution of 127 points per inch. To that purpose, we used a camera Canon EOS 600D with a lens Canon EF 24 mm f/1.4L ll USM, in addition to auxiliary enlightening with a controlled power. To access to the elevated zones in order to document all the mural paintings we made an elevated platform, chosen by the editors of the intervention projects, specifically to this purpose.
