None of the works of Chrysococces have been printed, although their publication would
apparently be a valuable acquisition to the history of astronomy.
Works in MS
His principal works extant in MS. are:
Expositio in Constructionem Persarum per Capita 47, cum
Astronomicis Designationibus, et Geographicis TabulisἘξήγησις εἰς τὴν σύνταξιν τῶν Περσῶν ἐν κεφαλαίοις
μξ́, σὺν τοῖς Ἀστρονομικοῖσδιαγράμμασικαὶ
Γεωγραφικοῖς πίναξιν,
Expositio in Constructionem
Persarum per Capita 47, cum Astronomicis Designationibus, et Geographicis Tabulis,
in the Bibl. Ambrosiana. It seems that this work is the same which we find in the Royal
Library at Paris, under the title
Γεωργίου τοῦ Χρυσοκόκκη τοῦ
ἰατροῦ Ἀστρονομικά.>
De inveniendis Syzygiis Lunae solaribus per singulos Anni
MensesThere is another Codex in the same library, entitled
Γεωργίον
ἰατροῦ τοῦ Χρυσοκόκκη περὶ τῆς εὑρήσεως τῆς ἡμέρας τῆς ἁπλῶς συξυγίας
ἡλίου καὶ σελήυης,
De inveniendis Syzygiis Lunae
solaribus per singulos Anni Menses. In the Royal Library at Madrid is *Pw=s dei=

Quomodo
construendum sit Horoscopium, aut Astrolabium. Editio et Expositio Syntagmatis Canonum Astronomicorum
JudaicorumA codex in the Ambrosian Library, inscribed Ἔκδοσις εἰς τὸ
ʼιουδαικον Ἐξαπτέρυγον,
Editio et Expositio Syntagmatis
Canonum Astronomicorum Judaicorum, is attributed to Georgius Chrysococces, who has
also left a MS. of Homer's Odyssey, written and accompanied with scholia by himself, in the
year of the world 6844 (
A. D. 1336), as it is said in the copy of
this work which was formerly in the Bibl. Palatina at Heidelberg, whence it was sent to
Rome by the Spaniards, and kept in the Vatican library till 1815, when it was sent back to
Heidelberg with the rest of the Palatine library by order of pope Pius VII.
History of the Byzantine Empire
It is doubtful if Georgius Chrysococces is the same Chrysococces who wrote a history of
the Byzantine empire, of which a fragment on the murder of sultan Mürad I. in A. D. 1389 is given by Fabricius. The complete astronomical works of
Chrysococces, as stated above, have not been published, but several of his Astronomical and
Geographical tables have been inserted in various modern works on Astronomy and
Geography.
