Xanthus of Lydia who lived around the same time Pericles lived was the first Greek to actually mention Zoroaster.
According to Pearson, the leading scholar on Xanthus and his contemporaries, as cited in
the Wiki article, "It is believed that Xanthus had some knowledge of Persian traditions, and it is plausible that he, a Lydian, would write about Persian religion, but it seems unlikely due to the available evidence." As with many ancient authors, Xanthus got a lot of "pseudepigrapha" attributed to him (books claiming to be by some ancient authority, actually freshly composed). His genuine work, although composed in a peculiar dialect of Greek, was all about the Lydians (speakers of a language somewhat like Hittite, the branch of Indo-European most distant from all the others) and in the "chauvinist" style: that is, claiming that every great idea in the world originated in Lydia; I have mentioned the "Hindu chauvinists" who claim that India is the origin of all civilization; and you, my friend, are a prime example of "Iranian chauvinism." Examples of "Greek chauvinism" are the quote from Strabo you mentioned some pages back, where he says Persians call worship
yasna because Jason and the Argonauts taught them how to worship (that is, those barbarous Persians wouldn't know anything about religion if Greeks hadn't shown them!) or the only passage in Plato I can find about Persians, where he says that Achaemenes (the dynastic founder) was the son of Perseus and Andromeda (how could he have been great if he didn't have a Greek father?)
We do not have any extract from Xanthus talking about Zoroaster, or Persia at all. What we have is that strange quote in Diogenes Laertius where he says Zoroaster was "6000" or "600" years before Xerxes, and claims Xanthus as his source: but Pearson thinks this would be a reference to some pseudepigraph that wasn't written by Xanthus at all; there is also some discussion of the Diogenes quote in your source here:
...this source discusses a 1700-600 B.C. date for Zoroaster.
Zoroaster General Survey
which says it could go back to "Persian informants" (presumably through the intermediary of someone writing in Greek and pretending to be Xanthus of Lydia) like the chronologers who invent the artificial histories in "1000-year ages" which cannot taken seriously (the datings are not accurate even for well-known periods: your source points out that the Arsacid dynasty of the "Parthian" period is seriously compressed, since they were not well-remembered; they came from the far east, and never achieved much loyalty in the western empire, so that they did worse and worse against the Romans as time went on, until the Sassanians overthrew them and re-established Persia as a first-rank military power). But "6000 years ago" would have been back to the beginning of history, and the placement of Zoroaster then would have been just a garbling; the chronologies have this bit of data that Zoroaster was "258 years before Alexander" which has been taken much more seriously than the rest, because it is not a round number and is not the kind of thing that these chronologers would have wanted to invent out of nothing.
This would put Zoroaster ~600 BC in the reign of Cyrus the First (grandfather of Cyrus the Great), and a lot of scholars have taken that as solidly established: so did I, when we started this; but I am accepting the linguists' opinions you have cited that this is about six centuries too late for the dialect in which the Gathas are written (as for those, mentioned in your source, who think Zoroaster was completely legendary, or that the Gathas weren't written by him: that is the kind of arch-skeptic, like people who think Jesus of Nazareth never existed or the 19th-century disbelievers in the existence of any city of Troy, that I just find annoying; ancient sources do have their problems and distortions, but don't make up important people and places out of nothing). What is plausible is that this date represents the time when
the Achaemenid kingdom adopted Zoroastrianism as the state religion; not long after, we find
Vishtaspa ("Hytaspes" in Greek) father of Darius, named after the king
Vishtaspa whom Zoroaster converted: I am also annoyed by those who think the father of Darius was the only "real" Vishtaspa and that the king in the Avesta was based on him (the father of Darius was not a king at all, and the king in the Avesta is depicted as far to the east), rather taking it for granted that he was
named after the scriptural hero.
Your source does not really think that anywhere "from 1700 BC to 600 BC" is a plausible date for Zoroaster. Rather it is saying that the time when the Rig Veda was written (1700-1500?) is definitely too early (the Gathas are distinctively later than that) and the time when the Achaemenids converted (600?) is definitely too late (the religion must have been around for a while before then). About 1200 seems to be the emerging consensus.
Did this [th] > [ ] shift take place any earlier in Canannite?
It did not take place AT ALL in Canaanite. The shift of medial "t" ("medial" means in the middle of a word) to "th" and then to "h" and finally to nothing is something that happened in Persian, over lengthy periods, not reaching completion until medieval times. There were some similar shifts in Semitic: the feminine-singular-nominative ending shifted from
-at to
-ah early in the "Canaanit"e and "Aramaic" groups, later in the "Arabic" group, of Central Semitic (never in the "Akkadian" or East Semitic, or in the "Ethiopic" or South Semitic), but the feminine-plural
-ot and feminine-singular-constructive
-et were not affected, nor any other words with final "t"; between vowels or in final position, "t" did shift to "th" (Sephardic dialect) or "s" (Ashkenazic dialect) in early medieval Hebrew.
I'm not really sure what you mean here.
Na, I'm just talking about a two particular words which were significant in Zoroastrianism as well as in Hebrew.
Rather more than that. You are starting from the fact that the now-standard text of the Hebrew Torah was compiled in the Persian period ~450 BC to argue that major names (of the deity as well as ancestral heroes) and ideas were all made up out of nothing during the Persian period, denying that the linguistics indicates a very lengthy prior history. This is the same as arguing that, since the now-standard text of the Avesta was compiled in the Islamic period ~750 AD, its ideas and names can be derived from the Qur'an and Arabic, ignoring any indications that the Avestan literature had a long prior history.
Yeah, but can you be so sure that Cannanite appeared before Avestan if your saying Cannanite appeared 1800 B.C. and others are saying that Avestan appeared around 1500 B.C.?
NOBODY, as far as you have shown, thinks Avestan appeared around 1500 BC; your sources have rather indicated that such a date is clearly too early.
But I think your usage of the word "appeared" here is indicating some muddle-headedness about how languages develop. People in Canaan or Iran or anywhere else kept right on speaking, continuously, as they have been doing since they became "modern humans"; there are gradual shifts from one generation to the next all the time (teenagers now say "And he was, like, what are you talking about? and I go, like, I'm talking about what you did to me that night" where this usage of "like" to indicate a paraphrased quote did not exist in the English language when I grew up-- and I'm not all THAT ancient!) and no sharp "borders"; the people in England didn't say "We're going to stop speaking Anglo-Saxon now and start speaking Middle English" in some particular year (but the years after 1066 saw rapid changes due to the Norman French invasion, so we mark off "two different" languages around then).
Canaanite did not "appear" in 1800 BC in any sense except that we start to get abundant written attestations then, first from Ebla and then (around 1500) from Ugarit. Ebla used the Mesopotamian cuneiform, a difficult script of mixed syllabic/ideographic style: that is, the symbols either represent a full syllable, or else the idea of a word. For example, the "star" symbol is common for the syllable
an. because
Anu was the Sumerian god of heaven; but it was also used in Sumerian for the word "god" (which could also be spelled out in syllables as
din.gir.) or as a prefix to any god-name (a "man" symbol was prefixed to any man's name, a "woman" symbol to any woman's name, a "mountain" picture to any place-name, and "wood" or "metal" to the name of any tool made of those materials), and then in Akkadian it might still be used to write "god" (although in Akkadian that word was pronounced, and might be spelled out, as
i.lu.). The pronunciations are not always written very accurately because not every possible syllable had a mark: so when "Yaw" occurs from Ebla, we
don't know whether an "h" sound or two also occurred in the pronunciation, because Sumerian had no "h" so there were no syllable-markers that included "h" sounds. Ugaritic script gives us a better picture because (like the Old Persian script invented in the reign of Darius) it was cuneiform in mechanics (still made by scratching wedges into clay bricks) but
alphabetic in style, using 30 letters to indicate the consonants very precisely and the vowels vaguely.
What I mean by the "appearance" of Avestan as a distinct language is the shifting of "s" to "h" which distinguishes it from other old Indo-Iranian speeches. In 1500, we see no sign of that anywhere.
I did not know that. That is really interesting. Is Ashur where the place-names Assyria and Syria comes from too?
Correct. Before the Assyrian hegemony, "Syria" was known as
Aram (as in "Aramaic").
But when I said symbols I actually meant the winged disc with the man in the middle. Does that not appear in Sumerian art?
No. Wings on the solar disc are an occasional motif in
Egyptian art, however; it is thought this design may have become a symbol of royal power in Syria during the heyday of Pharaonic control. The man in the middle is not known before the Assyrians, however.
The Sumerians and the Iranians both bore "Afghanian" bone structure, if I'm interpreting this correctly. Other sources mention how Sumerian features can be found as far east as Baluchistan.
As I mentioned in the "Celtic/Saxon" thread, it is usually the case that language replacement really involved only a small conquering elite who imposed their political control and cultural ways on the common people, not thorough genocides and replacement of the whole population (although the old elite may well have been slaughtered). The Vedas speak of the upper castes (priestly Brahmans and kingly Kshatriyas) as the "lighter" castes and the lower (mercantile Vaisyas and peasant Sudras) as the "darker"; this is generally taken to mean that there was quite a distinction of skin-tone between the invading Indo-Aryans and the previous population (speaking Dravidian and Munda languages); but by this time you cannot really see much genetic difference among castes, indicating that religious prohibitions against intermarriage have not really been very successful over the long term; the population of the south is somewhat darker than in the north, but all over India it looks as if the population has only a small minority (somewhat more in the north somewhat less in the south) of "Indo-Aryan" genetic ancestry. Despite the language, therefore, the people of India are MOSTLY descended from the people who were in India before any Indo-Europeans showed up at all. The same is true in Iran: despite all speaking "Iranian" languages, you are not mostly descended from the people who brought those languages with them into Iran, but from the people (Elamites, Guti, Meluhhans etc.) who were there before.
