I present some few results of my study on the mathematical content of the published part (f. 11r–126r) [8] of the Codex Vindobonensis phil. Graecus 65 (Tractatus Mathematicus Vindobonensis Graecus or TractMathVindGr) which the author is anonymous. The other part f. 126v-140r. has been published by H. Hunger and K. Vogel in 1963. This 15th century (1436) Byzantine MS includes the solution of problems of practical arithmetic, and algebra, the roots of which can be traced back to antiquity and their comparison with modern mathematical methods and terminology [9] reveals -apart from some differences- many identities and similarities showing the unbroken continuity of mathematical tradition through the centuries.
