Chant van de mystici: #goddelijke Gregoriaanse "Signum Magnum"
Signum Magnum is the title of the Gregorian Chant for the Introit of the Feast of the Assumption of Virgin Mary, in August 15 and was given in 1951. It is similar to Puer Natus, the chant used for the Introit for Christmas Day. Joyous, while observing the solemnity of the feast, Signum Magnum is drawn from the opening of Revelation 12 in Sacred Scripture.
