The Catholic cathedral of St. Joseph in Buffalo, New York, recently discovered a long-lost piece of its own history, tucked away in the corner of the building's sacristy. A rare tapestry - apparently a gift from Pope Pius IX (d. 1878) to the diocese's first bishop, Bishop John Timon (d. 1867).
The design of the tapestry displays the feasts on the Church calendar (as it stood in the 1860s) for all 365 days of the year. For each feast day, a relic is sewn into the fabric. Relics of hundreds of saints are joined to the tapestry and, in the center is a relic of the True Cross - a tiny sliver of wood from what it believed to be the Cross of Christ. The relic of the True Cross is surrounded by the Latin words: "In hoc, vinces" (In this, conquer) - an ancient motto connected with Constantine, the first Christian Roman Emperor.
You can read the full article from the Buffalo News about the historic find here. Just an all around cool Catholic story. FWIW, the reliquary/tapestry is now hanging prominently in the cathedral's sacristy.
