Antonio Vivaldi composed three settings of the Latin: Dixit Dominus|italic=no (The Lord said [unto my Lord]), the Latin version of Psalm 110. They include a setting in ten movements for five soloists, double choir and orchestra, RV 594, another setting in eleven movements for five voices, five-part choir and orchestra, RV 595, and a recently discovered setting in eleven movements for five soloists, choir and orchestra, RV 807, which had been attributed to Baldassare Galuppi. It is said to be one of his "most significant sacred works."
There are three recorded compositions of Dixit Dominus – Psalm 110 in Latin (or Psalm 109 in the Vulgate) – by Vivaldi. Each is an extended setting of the vespers psalm for five soloists, choir and orchestra; one only having been identified as his work in 2005.
Psalm 110 is regularly included in Vespers services, usually as the opening psalm. Dixit Dominus has been said to be one of his "most significant sacred works".
Vivaldi's best-known setting, catalogued as RV 594, is structured in ten movements, eight psalm verses and two movements for the doxology. It is set for soloists, double choir and orchestra. Set in D major, it is scored for two sopranos, alto, tenor and bass soloists, two SATB choirs and orchestras. The first choir (Coro I) is accompanied by two oboes, two trumpets (with timpani), two violins, viola, organ and Italian: [[basso continuo]]|italic=no, while the second choir (Coro II) is accompanied by strings, organ and continuo. The duration is given as 25 minutes.

The setting discovered next was catalogued as RV 595. Also in D major, it is structured in eleven movements, eight psalm verses and three movements for the doxology. It is scored for two sopranos, alto, tenor and bass soloists, a choir which also calls for divided soprano in some movements, and an orchestra comprising strings, two oboes, trumpet, and continuo bass.
The eleven movements are:
The Vivaldi setting catalogued as RV 807 was identified as his work only in 2005, having been thought to have been written by Baldassare Galuppi. A handwritten copy held by the Saxon State and University Library Dresden (Sächsische Staatsbibliothek) in Dresden is titled "Dixit a 4: con strumenti / del Sig: Baldasar Galuppi, detto Buranello / Fatto per l'Ospedale delli Mendicanti / 1745". Set in D-major, it is scored for two sopranos, alto and two tenor soloists, choir and an orchestra of two bassoons, trumpet, strings and continuo. A reviewer of its first recording described it as a masterpiece with "bold, intensely coloured rhetoric".
