A set of twelve concertos was published by
Estienne Roger in 1716-1717 under
Antonio Vivaldi's name, as his Opus 7. They were in two volumes, each containing concertos numbered 1-6. Of the set, ten were for violin solo; the other two were for oboe solo. The authenticity of some of the works included has long been doubted by scholars. Three are now considered spurious (i.e. not in fact by Vivaldi) for stylistic reasons. They are: No. 1 in B-flat major for oboe, RV Anh. 143 (formerly RV 465); No. 7 in B-flat major for oboe, RV Anh. 142 (formerly RV 464); and No. 9 in B-flat major for violin, RV Anh. 153 (formerly RV 373).
