Help needed for a strange Nemesis

[Jochen]

Dear friends!

I need help for a strange Nemesis/Aequitas of Nikopolis:

Moesia inferior, Nikopolis ad Istrum, Elagabal, AD 218-222
AE 27, 10.79g, 26.78mm, 15°
struck under governor Novius Rufus
obv. [AVT K] M AVR - AN[TWNEINOC]
Laureate head r.
rev. VP NOBIOV ROVFOV NIKOPOLITWN PRO (PR ligate)
in upper l. field one below the other C IC / TR
in r. field ON
Nemesis-Aequitas in long garment and mantle stg. l., holding goad in l. arm and in
extended r. hand scales; no wheel; over l. shoulder strange longish object with knob at top.
ref. a) AMNG I/1, 1962 (1 ex., Milano); object over her l. shoulder not mentioned!
b) Varbanov (engl.) 4048 (= AMNG 1962)
c) Hristova-Hoeft-Jekov (2018) No. 8.26.35.5 (this coin)
scarce, F/F+, dark green patina, patina damage on obv.

This strange object I have found only on this type. I have listed the possibilities which came in my mind:
(1) It is only a die break. But the coin from Wildwinds have it in another shape with knots!
(2) Part of her hairdo: Rather not
(3) A quiver, but the quiver is seen usually over the right shoulder
(4) Scabbard for sword, but I have never seen a Nemesis with sword
(5) Cubit or measuring rod. That would match the pic from Wildwinds where it has knots = marks of the cubit

I think the most probable is the cubit. What do you think?

I have attached a scsan of my coin (upper one) and the coin from Wildwinds (lower one)

Best regards

I would suggest it's connected to the object in the left hand which I do not believe is a Goad

A goad is a basic pointy stick used as a cattle prod

The item in her left hand has right angle protrusions. It does not appear as a pointed stick!  But I have no suggestion. If the item over the shoulder is a cubit perhaps the item in hand is some type of building or measuring device.

Was there Imperial construction in Moesia that this might be referencing? Something granted them by Elagabalus.
