and attended church "on a date and in a place where [the feast] was celebrated". Jacques Pantaléon of Troyes was also won over to the cause of the Feast of Corpus Christi during his ministry as Archdeacon in Liège under the diocesan bishop Robert of Thourotte. It was he who, having become Pope as Urban IV in 1264, instituted the Solemnity of Corpus Christi on the Thursday after Pentecost as a feast for the entire Latin Church, by the papal bull Transiturus de hoc mundo. The legend that this act was inspired by a procession to Orvieto in 1263, after a village priest in Bolsena and his congregation witnessed a Eucharistic miracle of a bleeding consecrated host at Bolsena, has been called into question by scholars who note problems in the dating of the alleged miracle, whose tradition begins in the 14th century, and the interests of Urban IV, a former Archdeacon in Liège. Though this was the first papally imposed universal feast for the Latin Church, it was not in fact widely celebrated for half a century, although it was adopted by a number of dioceses in Germany and by the Cistercians, and in 1295 was celebrated in Venice. It became a truly universal feast only after the bull of Urban IV was included in the collection of laws known as the Clementines, compiled under Pope Clement V, but promulgated only by his successor Pope John XXII in 1317. While the institution of the Eucharist is celebrated on Holy (Maundy) Thursday, the liturgy on that day also commemorates Christ's washing of the disciples' feet, the institution of the priesthood and the agony in the Garden of Gethsemane. So many other functions took place on this day that the principal event was almost lost sight of. This is mentioned in the Bull Transiturus as the chief reason for the introduction of the new feast. Hence, the feast of Corpus Christi was established to create a feast focused solely on the Holy Eucharist. Three versions of the office for the feast of Corpus Christi in extant manuscripts provide evidence for the Liège origins and voice of Juliana in an original office, which was followed by two later versions of the office. A highly sophisticated and polished version can be found in BNF 1143, a musical manuscript devoted entirely to the feast, upon which there is wide scholarly agreement: the version in
