wrote at least three Gloria settings. Only two survive (RV588 and
RV589) whilst the other (RV590) is presumably lost. RV588 is the lesser
known of the two surviving Glorias, while RV589 is the most familiar and
popular piece of sacred music by Vivaldi. If you are looking for
Vivaldi's Gloria without specific reference to RV588, you should
probably consider RV589.
