Christ Glorified in the Court of Heaven, Fra Angelico - 1428-30
"The glorious company of the apostles praise Thee.
The goodly fellowship of the prophets praise Thee.
The white-robed army of martyrs praise Thee.
All Thy saints and elect with one voice do acknowledge Thee,
O Blessed Trinity, one God!"
(Feast of All Saints, Antiphon at Lauds from the Te Deum)
