L'ÉVEQUE, Henri.- Costume of Portugal.- [London: Colnaghi and Edmund Lloyd, 1812-1814].- [1, 52] f.: [50] gravuras color.; 35 cm.- E. Henri l’Éveque (1769-1832), Swiss traveller, painter, watercolourist and engraver, born in Geneva, was in Portugal several times, having graphically recorded, among other subjects, numerous episodes of the French Invasions. His "Costume of Portugal" is considered the most beautiful book of Portuguese usages published during the 19th century and an important source for the iconography of Portuguese costume of his time. Without the title page, which was never printed, the edition consists of a page with the title, followed by another with the dedication printed to the councilor, minister and secretary of state António de Araújo de Azevedo, first Count of Barca (1754-1817) and a third sheet with the index of the engravings in Portuguese. Next, 50 numbered aquatints, coloured by hand, interspersed with 52 sheets of bilingual texts, in English and French, describing the respective images. Copy with stain on the edge, progressively affecting the outer margins of the last 11 engravings and respective text sheets (maximum 140x60 mm). The copy has a crowned oval stamp (on the first page) and a circular book stamp, also crowned, gold engraved, at the foot of the spine, ownership marks that, in the pencil inscription on the free endpaper, are attributed to Augustus Frederick (1773-1843), Duke of Sussex, sixth male child (ninth son) of King George III of the United Kingdom (attribution that could not be confirmed). The remaining plates are very clean and well preserved. Full brown morocco binding, with peripheral ornamental borders with three simple fillets and florets in the corners of the covers, closed panels on the smooth spine and rolls on the squares (protective case). Duarte de Sousa, 422.
