Variation of St. Bartholomew's Day (Double Repost)

From my 1911 Missale Romanum

You will recall a few days ago a post displaying a photo of my 1911 Missale Romanum, which indicates that within the city of Rome St. Bartholomew's feast is to be celebrated on August 25th, as opposed to the broader celebration on August 24th. The other day, at Sunday Divine Liturgy, we commemorated the Saint, which I assumed to be a lingering Latinization that had not yet been discarded. A quick look revealed that the Antiochian Orthodox and the Greek Orthodox also observe St. Bartholomew on the Roman day. According to Rubricarius of the St. Lawrence Press the differing dates have to do with the transfer of the Apostle's relics the date of which was observed as the feast in Rome and in the Eastern rites. Gregory DiPippo relates that while the Latin Church observed the feast on the 24th a major celebration would take place at the Basilica of St. Bartholomew on Tiber Island with the help of Rome's Greek community. The Sacred Congregation for Rites, not always a historically informed committee, axed this variation on October 28th, 1913 in accordance with the reforms Divino Afflatu began two years prior. The record of the relevant decree can be found here on page 463, section V, item d.
