Veni, Sancte Spiritus, reple tuorum corda fidelium, et tui amoris in eis ignem accende: qui per diversitatem linguarum cunctarum, gentes in unitatem fidei congregasti, alleluia, alleluia, alleluia.

The Pentecost Dome of the Basilica of Saint Mark in Venice.

Come, Holy Spirit, fill the hearts of Thy faithful, and kindle within them the fire of Thy love; who through the variety of all tongues, didst gather the nations into the unity of the faith, alleluia, alleluia, alleluia.  (The antiphon for the Psalms of First Vespers of Pentecost in the Dominican Breviary.)
