Maria Chalkou, «The Mathematical content of the Codex Vindobonensis phil. gr. 65 of the 15th cent. Introduction, Edition and Comments, Byzantine Research Center, Thessaloniki 2006», at "LEXIKON ZUR BYZANTINISCHEN GRÄZITÄT"

The site "LEXIKON ZUR BYZANTINISCHEN GRÄZITÄT"  is the result of a collaboration between the Lexikon zur byzantinischen Gräzität (LBG) published by the Austrian Academy of Sciences (Die Österreichische Akademie der Wissenschaften) and the Thesaurus Linguae Graecae® (TLG®) at the University of California, Irvine.
The LBG is the foremost lexicographical resource in Byzantine Studies mainly covering the period from the 4th to the 15th century A.D. taken from more than 3,000 texts. Seven fascicles have appeared to date, with one more scheduled to appear in 2016. When completed the dictionary will consist of more than 2,000 printed pages, containing approx. 80,000 lemmata.
In March 2012, the LBG and TLG began conversations about digitizing the existing volumes of LBG and linking them to the TLG texts.  The TLG team (Nick Nicholas, Maria Pantelia and John Salatas) worked on converting the files into XML format and incorporating them into the TLG online system. The first six fascicles have been included in this release covering letters A-P. They can be accessed at:
The LBG was initiated by Erich Trapp – in collaboration with Wolfram Hörandner and Johannes Diethart – in the early 1990s. It became a joint project of the Commission for Byzantine Studies at the Austrian Academy of Sciences, the Department of Philology at the University of Bonn and the Department of Byzantine and Modern Greek Studies at the University of Vienna, financially supported by the Austrian National Science Fund (FWF).
Astrid Steiner-Weber, Sonja Schönauer and Maria Cassiotou-Panayotopoulos contributed to the project at Bonn University with the financial support of the German Research Foundation (DFG),. The Lexicon is now continued at the Division of Byzantine Research of the Institute for Medieval Research at the Austrian Academy of Sciences under the guidance of Erich Trapp (Vienna/Bonn). Members of the team in Vienna include Carolina Cupane, Andreas Rhoby and Elisabeth Schiffer.
LBG and TLG® wish to acknowledge the contribution of the Austrian Academy of Sciences that has generously supported the creation of the LBG and has now agreed to its online dissemination for the benefit of the scholarly community.

Byzantine metrology

Ἡ Μετρολογία στὸ Βυζάντιο
Στοιχεῖα ἀπὸ τὸν Codex Vindobonensis phil. Gr. 65 τοῦ 15ου αἰ.
Τὸ "μοδίον" εἶναι νόμισμα γῆς (κεφ. 224)[1] καὶ ἰσοδυναμεῖ μὲ τὴν ἀξία ἑνὸς  τετραγωνικοῦ ἀγροτεμαχίου πλευρᾶς 10 οὐργιῶν καὶ ἐμβαδοῦ 100 τετρ. οὐργιῶν. Ἰσχύουν οἱ σχέσεις[2]: 1 μοδίον= 2 σχοινία= 40 λίτρες= 200 οὐργίες= 888,73 (ἢ 939,18) τετρ. μέτρα. Τὸ "μοδίον" εἶναι φορολογικὸς ὅρος[3] καὶ ὄχι μονάδα βάρους[4],  γι' αὐτὸ καὶ ἡ ἰσοδυναμία του πρὸς τὶς οὐργίες ἐξαρτᾶται ἀπὸ τὴν ποιότητα τῆς γῆς, δηλαδὴ τοῦ ἐδάφους τοῦ ἀγροῦ. Ἔτσι 1 μοδίον ἀγροῦ μπορεῖ νὰ ἀντιστοιχεῖ σὲ 100, 200, ἢ 288 οὐργίες. Τὸ "μοδίον"  σὲ ὁρισμένα προβλήματα (κεφ. 231) λαμβάνεται καὶ ὡς μονάδα ὄγκου.
