The study of Kalendars brings one into constant contact with hagiology, the acts of martyrs, and the lives of saints. It would however have been obviously vain to deal seriously in the present volume with so vast a subject, even in broadest outline. A short Bibliography of some important or serviceable works dealing with various branches of the subject before us is prefixed. A SHORT BIBLIOGRAPHY ACHELIS, H. _Die Martyrologien, ihre Geschichte und ihr Werth._ (Berlin, 1900.) ACTA SANCTORVM. [Of the Bollandists. This vast collection, of which the first volume appeared in 1643, had attained by the middle of the nineteenth century, after various interruptions in the labours of the compilers, to 55 volumes, folio, and the work is still in process, having now reached the early days of November. Various Kalendars and Martyrologies have been printed in the work. The Martyrology of Venerable Bede, with the additions of Florus and others, will be found in the second volume for March; the metrical Ephemerides of the Greeks and Russians in the first volume for May; Usuard’s Martyrology in the sixth and seventh volumes for June, and also an abbreviated form of the Hieronymian. The second volume for November contains the Syriac Martyrology of Dr Wright edited afresh by R. Graffin with a translation into Greek by Duchesne. The same volume contains the Hieronymian Martyrology edited by De Rossi and Duchesne.] ASSEMANUS, JOSEPHUS SIMON. _Kalendaria Ecclesiae Universae, in quibus tum ex vetustis marmoribus, tum ex codicibus, tabulis, parietinis, pictis, scriptis scalptisve Sanctorum nomina, imagines, et festi per annum dies Ecclesiarum Orientis et Occidentis, praemissis uniuscujusque Ecclesiae originibus, recensentur, describuntur, notisque illustrantur._ 4to, 6 tom. Romae, 1755. The title raises hopes which are not verified. [This work of the learned Syrian, who for his services to sacred erudition was made Prefect of the Library of the Vatican, was planned on a colossal scale, but it was never completed, and indeed we may truly say only begun. The six volumes which alone remain are wholly concerned with the Slavonic Church. The first four volumes, together with a large part of the fifth, are devoted mainly to the history of Slavonic Christianity. The concluding part of the fifth and the whole of the sixth volume deal with a Russian Kalendar, commencing the year, as in the Greek Church, with 1 September. This is treated very fully, but the work ends here.] BAILLET, ADRIEN. _Les Vies des Saints._ 2nd Ed. 10 vols. 4to. 1739. [The ninth volume on the moveable feasts abounds in valuable information; and, generally, this work may be consulted on the history of the festivals with much profit.]
