Iam Christus Astra Ascenderat

views updated


Office hymn that was historically prescribed for Matins on the feast of Pentecost. It dates from the fourth or fifth century and some ascribe the hymn to St. am brose. Others disagree, however, basing their opinion in part on metrical variations that are unusual in Ambrosian hymns. The hymn, in eight strophes, is a somewhat pedestrian metrical setting of Acts 2.116, describing the coming of the Holy Spirit upon the Apostles, the miracle of tongues, and St. Peter's response to the charge of drunkenness made by some of the mystified hearers. The meter is iambic dimeter.
