Hi Chris - Thanks for your interest.

P 356 does appear in both Faulkner and Sethe – see Utt. 511 §1155b. Faulkner (p. 187) translates this passage as “the Horizon dwellers will come to me…”. Allen, p. 154, translates it as “those of the Akhet shall come to him…”. You can see the actual glyphs in Sethe, V. II p. 145 at the beginning of line 1155b where the word is written “iwtn-f”. Note that there is no “sun” determinative. [www3.lib.uchicago.edu]
I don’t know where the translation you cited comes from, but I think it is off the mark.

This line can also be found in Maspero’s Inscriptions, p. 202 - [archive.org]

I based my statement that the word "itn" meaning “sun-disk” does not occur in the PT’s on Hannig’s Worterbuch I p. 236, where the only OK example he cites is that from the Abusir Papyri that I referred to.

As to your question regarding an explanation of the circumpolar contexts of the texts I cited – this is a much more complicated undertaking as it involves many different layers and strands of context. I am currently working on a detailed paper that goes into much of this, but I will try here to briefly touch on some of the factors.

Starting with CT Sp 47 – in line 205 we see that the dead king will “ascend to the sky on the day of the Six-day festival” where he will appear “as Lord of the West at the head of the gods”. As with the many examples in the PT’s, this ascension is clearly one in which the deceased is making his journey to the stars of the circumpolar region. I trust that you are familiar enough with these texts and don’t need this to be elaborated upon. As in the PT’s, there is here also mention of the Two Conclaves – a corroborative reference to the fact that the context is circumpolar.

The situation is by coincidence actually quite similar to that seen in Utt 511 mentioned above. If one looks further at passage §1155, one reads, “Dw3w will come to me rejoicing and the gods in homage; the Horizon dwellers will come to me on their faces and the Imperishable stars bowing down”, and then later in §1159 the king says, “I will be as effective as Spd-wr, I will preside at the head of the Two Conclaves..”

In Sp 47, then, I believe that we can then question exactly who the god is that is being referred to in line 208, where it says “The god who is in his horizon awakes, acclamation is given to him (ie, the deceased - and now risen - king) in the Two Conclaves”. If the context is circumpolar, and if the “god who is in his horizon” is not the solar Re, then the king’s “seat within the Disk (itn)” may in fact be referring to something quite different that the king’s seat in the (so-called) solar bark of Re. The “disk” in this context may have a totally different set of associations than a reference to the “sun’s disk”.

Sp 50 bears some of the same reference points as Sp 47, but it also touches on a number of other ‘mythological’ circumpolar associations. I can’t here go into all of this, but will just mention some of those regarding the place name of “Ninsu” (line 225). In Sp 335 b, Part I (line 210) we have,

“I have bathed in those two very great lagoons which are in Ninsu..Who is he? He is Re himself. What are the two very great lagoons? They are the Lake of Natron and the Lake of M’3t. I proceed on the path which I know in the direction of the Island of the Just. What is it? It is the path on which my father Atum went when he proceeded to the Field of Rushes. I arrive at the Land of the Horizon dwellers in the sky”.

Many times, in the PT’s the Field of Rushes is closely associated with the circumpolar region and with the Imperishable Stars, if not even clearly identified as being in the circumpolar region. I believe you are already familiar with such references in the PT's.

In Sp 335b Part II (line 325) we have Ninsu associated with Mskt, “As for the Mskt, it is the knknt in Ninsu”, (Mskt, itself, having numerous associations with the northern stars – see Sp. 383 and Sp 789, or Utt 475.). Further – in CT Sp 337 we have Ninsu associated with “the Great Tribunal which is in On”, with this “Great Tribunal” being “in the great ploughing of the land in Ninsu.” (Also see Sp 26) And yet further in Sp 337, there is a connection of Ninsu with the Two Conclaves, “Horus is joyful, and the Two Conclaves are pleased at it , And all of this evidently being associated with the battles between Horus and Seth (Ursa Major and Ursa Minor) – “I restored the Eye after it had been injured on that day when the (two) Rivals fought” (Sp 335 a, Part I line 232).

Sp 186, 220, 225 (which I inadvertently omitted previously), and 1029 – all seem to revolve around a common myth, whatever it was – but variations of which included a reference to having a meal under a “sycamore tree which is south of Nefrusi” and “under the tresses of ‘Itn-ws’” (Sp 186, line 87). In Sp 220, line 203 we have “I travel upon that upper road of the sky and that lower road of the earth north of ‘Itn-ws, I eat on the Field of Offerings, on the Lake of Turquoise…” In Sp 225 it is “may you sit under the branches of the myrrh tree near Hathor who is pre-eminent in ‘Itn-ws’ when she travels to On….” (“Hathor, Mistress of the northern sky” – Sp 332). Sp 1029 is indeed written more in what would on the surface appear to be a solar context, but here, too, I would argue that as a result of the other “itn-ws’ references I feel it safe to assume this also has a part of its roots in a more circumpolar setting. The rising in the east in these texts, more often than not, referring to the movement of Re in his circuit around the pole to the eastern side of the northern night sky. The language used allows of these two separate interpretations – one solar, and one circumpolar. Each being valid to the participant, depending on either one's need or desire for this or that contextual association. To get more of a sense of all this one can research in the PT’s those texts that deal with the Field of Rushes, the Field of Offerings, and the associations connected with the usage of the sycamore tree and turquoise symbol, etc. The Horus and Seth association with the Dippers is one I feel should be somewhat self-evident - but if not, there is literature out there which goes into it - although not all get it right as to which is which.

There is much, much more I could go into, but I don't want, nor do I have the time, to do that here.
