3. The sacramentary in the cathedral library of Cologne (codex 88, fol. 3-9) contains a complete calendar for this cathedral. It is essentially the Roman Calendar of the ninth century, with the addition of the local saints of Cologne, the two Ewalds, Kunibert, Brictius, Quintinus, Severin, Gereon and his 318 companions, the 360 Moors, and the 11,000 virgins without Ursula, and designated simply as virgins. Other names deserving notice are: Briga (Brigida) 1st February, Arealis (?) 28th April, _Marcus episcopus_, Boniface the martyr, Medard, Lambert, and Mauricius with 6666 companions. The calendar belongs to the second half of the ninth century, and is proved to have belonged to the cathedral of Cologne begun by Hildebold and consecrated by Willibert in 873, by the fact that it gives the day of the consecration of the cathedral correctly (23rd September), and is described as belonging to the Church of St Peter, to whom the former cathedral was dedicated. The sacramentary, but not the calendar, has been printed by J. Pamelius in his “Liturgicon Ecclesiæ Latinæ,” tom. ii. (Col. Agr. 1571), but unfortunately with so many arbitrary alterations that it is quite useless as an edition of the text. 4. In the library at Düsseldorf there is a sacramentary, (codex D. I.) written in the lifetime of Bishop Altfrid of Hildesheim († 874), which contains (fol. 217-222) a calendar showing northern French influence. Only the 11,000 virgins are given of the local saints of Cologne, and here again Ursula is not named, and the virgins are not called martyrs. The book belonged to the Convent of Essen on the Ruhr founded by Altfrid. This MS. gives in fol. 64 A the order of the festivals observed within the jurisdiction of the monastery during the ninth century: “Istas præcipuas solemnitates in anno totus populus sabbatizare debet: In die Nat. Domini dies IV., in octabas Domini, in Teophania, in Purificatione Mariæ, in Pascha Domini dies IV., in Ascensione Domini, in Pentecoste dies IV., in Nat. S. Johannis, in Nat. Sanctorum Apostolorum Petri et Pauli, in Assumptione S. Mariæ, in Nat. S. Remedii [Remigii], in Missa Michahelis, in Solemnitate Omnium Sanctorum, in Nat. S. Martini, in Nat. S. Andreæ.” Binterim published a Cologne calendar, apparently of the ninth century, under the title _Kalendarium Ecclesiæ Germ. Coloniensis Sæculi Noni_ (Cologne, 1824), and Harless attributes it to the second half of the same century (Archiv. f. die Gesch. des Niederrheins, vi. 67). It is, however, much later, for it gives all the feasts of the apostles, and provides them with vigils, and all the days of the year are filled in with the names of saints. For these reasons I should date the calendar as belonging to the eleventh century at the earliest.
