Is a composition of two translations another translation?

Answer 1

In simple terms, there are two types of complex translations: one involving one source language and the other involving two source languages or more. To make a composite translation uniformed, a good editor, being a professional in both languages is required. If we take a piece of fiction containing poems, songs or other inclusions in any other than main foreign language, they might be translated separately and incorporated later, still the the translator of the body text would be considered as a prime translator of that piece of writing, even if there are lots of other language inclusions (while their translator's name must be mentioned somewhere in the book). If a composition or combination of two translations of a single piece of writing is dealt with, it can be viewed as a single translation, because one integral piece of, say, fiction is the object of translation. If a single piece of writing in one source language has been translated by two or more translators, still this would be one translation. At this point, an experienced translator should proof-read and overview the translation done. Those two translator might yield their own translations of certain chapters, sections, it would not be another translation since the book as a piece of art is indivisible. As a rule especially, in printing media, no indication of many translators of several contributions in ONE article is not made. So in this case, it's one translation.

Answer 2

Yes, the composition of two translations is also a translation. When you combine two translations, the resulting transformation is also a translation, because translations preserve the shape and orientation of the original object.
