Abundius was born at
Thessalonica. Around 448 Abundius became the fourth
Bishop of Como, succeeding
Amantius. He was present at the
Council of Constantinople in 448, and took an active part against the
Eutychian heresy at
Chalcedon (451), where he was the representative of
Pope Leo the Great. In 452 he also took part in the
Council of Milan, convened to refute the same heresy. Abundius is one of those to whom the authorship of the
Te Deum is attributed. The
Romanesque church of Sant'Abbondio at Como, consecrated in 1095 by
Pope Urban II, is dedicated to him, and his
relics are conserved beneath its principal
altar. ==References==
