Vasilissa ergo gaude

Vasilissa ergo gaude ("Therefore rejoice, princess") is an isorhythmic motet by the Renaissance composer Guillaume Dufay. In terms of its subject matter, it is sometimes grouped together with Lamentatio sanctae matris ecclesiae Constantinopolitanae, Apostolus gloriosus and Balsamus et munda cera which are generically called Dufay's Byzantine motets. Its composition was occasioned by the marriage on 21 January 1421 of Cleofa Malatesta, daughter of Malatesta di Pandolfo, to Theodore II Palaiologos son of the Byzantine emperor Manuel II and Despot of the Morea. It has been surmised that the actual motet was composed in 1420 and is perhaps the earliest example of this choral form if not the earliest work attributed to Dufay. In earlier scholarship it was assumed that the motet's first performance had taken place on May 19, 1419 during the festivities prior to the marriage

Vasilissa, ergo gaude,
Quia es digna omni laude,
Cleophe, clara gestis
A tuis de Malatestis,
In Italia principibus
Magnis et nobilibus,

Therefore rejoice, princess,
for you are worthy of all praise,
Cleofe, glorious from the deeds
of your Malatesta kin,
leading men in Italy,
great and noble,

Ex tuo viro clarior,
Quia cunctis est nobilior:
Romeorum est despotus,
Quem colit mundus totus;
In porphyro est genitus,
A deo missus celitus

More glorious from your husband,
for he is nobler than all;
he is Despot of the Rhomaioi,
he whom all the world reveres;
he was born in the purple,
sent by god from heaven
