The dating of the ‘Earthquake of the Sabbatical Year’ of 749 C.E. in Palestine1

  • Yoram Tsafrir (a1) and Gideon Foerster (a1)

In the mid eighth century, towards the end of the Umayyad regime, a major earthquake occurred in Palestine and the East, of which we know from Christian, Jewish and Muslim sources. Archaeologists relate to destruction by this earthquake layers in several sites, such as Jerusalem, Gerasa in Arabia, and sites mostly along the Jordan valley, among them Kh. Mefjer near Jericho, Pella, Capernaum, Sussita-Hippos, and recently, Bet Shean-Scythopolis (see below).

The exact date of this earthquake is controversial; some scholars date it to 746, others to 747 or 748, In 1960, M. Margaliot suggested that the earthquake took place in 749. In this article we present new archaeological and numismatic evidence in support of this later date (see below p. 234, and pl.II).

23 Shalem, N. mentions briefly the existence of Christian sources for the earthquake dating it to 18 January 746, but with no further discussion: ‘On the date of the Tiberias earthquake’, Bulletin of the Jewish Palestine Society, 8,1941, 117 (in Hebrew). Shalem also mentions that Michael the Syrian describes an earthquake in the year 947 (misprinted for 749), but hedoes not explain this calculation.

24 Margaliot, art. cit. n. 9. See an additional list of fasts mentioning the 23rd of Shevat in: Fleischer, E., ‘Hadutha–Hadutahu–Chedweta–solving an old riddle, Tarbiz, 53, 1984, p. 95, n. 8 (in Hebrew).

25 Mahler, E., Handbuch der jüdischen Chronologie (Frankfurt, 1916; repr. Hildesheim, 1967), 546. According to Mahler, 18 January falls exactly on the 23rd of Shevat. According to another calculation it falls on the 24th of Shevat, Fried, N., Calendar for six thousands years, founded by A. A. Akavia (Jerusalem, 1976), 384 (in Hebrew).

In these earlier publications we used the dating of 747 or 748. Forthe new discoveries and the hoard, see ibid., 9,1990, 126–8.

28 One hypothesis for Theophanes's, inaccuracy in dating the year may be that he derived his information from a list of memorial days commemorated in churches during his period. This church calendar had to contain the exact day of the commemoration, but did not necessarily mention the precise year of the catastrophe, a task left to Theophanes. A similar phenomenon is found in the Jewish lists of fasts; they all mention the 23rd day of Shevat, but in only one case is the year of the earthquake mentioned (see above, p. 233–4). Compare the commemoration of an earthquake on 13 February in the church of St. Demetrius in Thessalonica, Garitte, G., Le calendrier palestinogèorgien du Sinaiticus 34 (X‘ siècle) (Brussels, 1958), 50, and discussion on p. 158. No such commemoration has hitherto been found in church calendars for 18 January; thus our suggestion must remain hypothetical.

33 One wonders whether this catastrophic event did not contribute to the fall of the Umayyad dynasty some time later; thisquestion, however, is beyond the scope of the present paper.

1 This is a revised version of an article published in Hebrew in Tarbiz, 58, 1989, 357–62. We owe thanks to M. Beit-Arieh, I. Hasson, J. Yahalom and I. Ta-Shema for their useful comments on that version. In particular, we owe thanks to A. El‘add and I.Karcz, who, after the publication of the Hebrew article, supplied us with many useful comments and further analyses of the various sources and traditions. These scholars also gave us access to typescripts of their own (as yet unpublished)papers, in which they consider the possibility that reports of more than one earthquake were conflated in the ancient sources.
