RESOURCESlogia Orientalia in Memoriam Ernst Herzfeld (Locust Valley, N.Y.,
1952), pp. 235--43, and "Monnaies sassanides et arabes proven ant
des fouilles de Bichapour," in Fouilles de Chap our, vo!. 11 of R. Girsh-
man's, Les Mosai'ques sassanides (Paris, 1956), pp. 185-91. The hoards
published by M. A. al-'Ush in The Silver Hoard of Damascus (Da-
mascus, 1972) and in Tresor de monnaies d'argent trouve a Umm
Hajarah (Damascus, 1972) contain both Sasanian and early Islamic
coins. P. Schinaja's "A Coin Hoard from Choche," Mesopotamia 2
(1967): 105-33, concerns 205 Sas ani an silver coins.
The Arab-Sasanian coins struck by the Muslims in the Sasanian style
following the conquest provide unique contemporary evidence for the
complexities of continuity and change. Serious scholarship appears to
begin with J. Walker's "Notes on Arab-Sasanian Coins," Numismatic
Chronicle (1934) and J. M. Unvala's "Quelques monnaies arabes a
l€gendes pehlevies et que!ques autres monnaies bilingues pehlevie-
arabes," Numismatic Chronicle (1937), pp. 280-96. However, the
classic presentation of such coins is J. Walker's A Catalogue of the
Arab-Sassanian Coins (London, 1941) for coins in the British Museum.
A. Guillou's Les monnayages pehlevi-arabes (Paris, 1953) does the
same for such coins in the Cabinet des M€dailles of the Bibliotheque
Nationale, but it was reviewed unfavorably by G. Miles in Ars Ori-
entalia 2 (1957): 591. More up-to-date general treatments are provided
by N. Naqshabandi in ad-Dirham al-islamt, al-Guz' al-awwal: ad-
Dirham al-islamt al-mafjrub 'ala t-tiraz as-saSant (Baghdad, 13 89/
1969), and H. Gaube's Arabosasanidische Numismatik (Brunswick,
1973).
More specialized studies include R. Girshman's "Une monnaie de
Zyad I. Abu Safian, Gouverneur du Fars," in Melanges Syriens offerts
a Monsieur Rene Dussaud (Paris, 1939), 11: 697-701; J. Walker's
"Some New Arab-Sassanian Coins," Numismatic Chronicle (1952),
pp. 106-110; and G. Miles's "Some Arab-Sasanian and Related Coins,"
ANSMN 7 (1957): 187-209. The three studies by R. Curie! called
"Monnaies Arabo-Sasanides," in Revue numismatique (1965), pp.
321-28; (1966), pp. 61-69; (1967), pp. 103-16, are particularly use-
ful in discussing the historical significance of certain coins. For Arab-
Sasanian coins struck at Basra, see W. al-Qazzaz, "an-Nuqiid al-is-
lamiyya al-ma4riiba bi-I-Ba~ra 'ala !-?riiz as-sasanI," Sumer 24 (1968):
127-29. Such a coin struck by Ibn al-Ash'ath during his rebellion and
now in the Iraq Museum is discussed in the article by al-Qazzaz on
"ad-Dirham al-islamI al-ma4riib 'ala !-?riiz as-sasanIli-'Abd ar-Ral)-
