Pistol: “pri {O1 D21 D54} to go up, ascend”
‘prt’ (heliacal) rising of Sopdet (Sirius) - the brightest star in their sky.
'ia' can mean 'ascend' (M17 (j) D36 (a) + det. ‘mastaba’):
".....you shall ascend (ia) to the god" P 334 (MN) (PT 483) Sethe Vol 2: 71; §1016d
‘ia’ can also mean ‘tomb’ (M17 (j) D36 (a) + det. ‘mastaba’)
"You have been given to your mother Nut in her identity of the burial place, she has collected you in her identity of the burial chamber, and you have been elevated (ia) to her in her identity of the tomb's superstructure (ia)." T 196 (PMN); PT 364; Sethe Vol 1: 331; §616f
Hrt is another word for tomb: D2 (Hr) D21 (r) X1 (t) + det. N25 'desert' / 'foreign land' det. N25
Hrt can also refer to the distant sky above: D2 (Hr) D21 (r) X1 (t) + det. N1 'sky' and derives from the root Hrj ‘be (come) far, distance.’
Translations of Hrt as the ‘sky’:
‘the above’ (Allen) / ‘celestial vault’ (Faulkner) / (Celestial) Distance (i.e. the sky) (Shmakov)
Sun Atum, this Unis has come to you - an imperishable akh, lord of the property of the place of the four papyrus columns. Your son has come to you, this Unis has come to you. You shall both traverse the above (Hrt), after gathering in the netherworld, and rise from the Akhet, from the place in which you have both become akh. W 150 (PT 217) Sethe Vol. 1: 87; §152c
Hr, ‘mortuary complex with pyramid’ D2 (Hr) D21 (r) X1 (t) + det. N25 'desert' / 'foreign land'.
These various references for tomb, ascend, sky share a common theme – the ascent of the deceased to the sky – the tomb itself associated with the sky personified by Nut, the sarcophagus chamber, the womb of Nut? (§616f)
