I have to disagree about Schmidt's translation. Riley's is often somewhat free, and occasionally wrong, but he does know Greek, and his English is clear and comprehensible. Schmidt's is the opposite of that, and he still misunderstood a lot. I think the impression of Schmidt staying close to the original is mostly a result of his English phrasing and terminology being so idiosyncratic. 'Cryptic and enigmatic' may actually be a better description of Schmidt's translation than of Valens' original! (Valens is disorganized, which he remarks on himself, but that's another matter.)
I haven't read Andrea Gehrz's translation, but Schönberger & Knobloch has its own problems...
That is of course your own prerogative, Martin. Having command of the language (ancient Greek in this case) is enough for translators in the vast majority of cases. However, when we get to technical concepts, when we get to concepts that are nowhere defined, it becomes mandatory to stay as close as possible to the original. Schmidt is by far the best here, because he worked with astrologers and eventually became a practising astrologer himself, whereas the translators are merely academics. I am not saying Schmidt is infallible.
What I am saying is because the topic of being abroad and emigration has not been treated by any other author in history (Ptolemy's few sentences is the only exception. I have given it, but it is so brief that it cannot be used unless the chart matches the exact configuration), while I was working on my tutorial and showing how the method is applied, I wanted to make sure I had the best version of the 4 translations.
The text itself is about 2300 words. My interpretation and explanation of the text is 9914 words. I urge any astrologer to try and understand what the text is saying. You will not be able to, not unless you dedicate yourself, and it will take a long time. And even if/when you do, then you will have to test and apply to method to actual charts, which Valens and the source he is quoting does not show. And on top of this, an absolutely vital piece of informaton is missing. I mean the Lot of Being Away from Home. Without figuring out which Lot this is, it is pretty much impossible to apply the method.
No surviving author is as cryptic and enigmatic as Valens. Ptolemy is not even close. And that is
one reason why astrologers teach Ptolemy, Dorotheus, Rhetorius, but not Valens.
There is a reason Valens demands oaths from his reader that contain curses those who fail to keep them. Unlike the above three authors and almost all others.
