Carpets displaying this striking design of stylized vegetal arabesques in yellow on a red ground are called "Lotto," after a famous altarpiece by the Italian Renaissance painter Lorenzo Lotto that includes a similar carpet. The motifs of the central surface show additional hooks and curls and render the overall impression more decorative, leading to the name "ornamental Lotto" given to this and similar carpets. The border of this example contains a design of cartouches and rosettes alternating on a deep blue background—a border pattern typical of "Transylvanian" carpets. Turkish in origin, so-called Transylvanian carpets were donated as pious gifts to churches throughout Romania and Hungary.
