"Silver Bowl with seated ruler, from Iran or Afghanistan, 11C" Topic

I first saw this Silver Bowl with seated ruler and attendants, from Iran or Afghanistan (Ghaznavid?), 11th century, State Hermitage Museum inv. S-499, St. Petersburg in a research paper, then found it on the museum's digital site. It wasn't referred to in the paper. Does anyone known anything about this bowl? The lions seem to have Chinese influence.
Having a throne supported by animals is typical of Sassanid enthronemnet scenes. The figures wear right-over-left coats with lapels.
Similar lapels are found on a Cup with horseman, Khwarezm c.7th-8th Century, State Hermitage Museum, St. Petersburg, a Bowl with figures in coat with lapels and hanging sleeves or shawl, 10th Century, Nishapur, Eastern Iran and on Kizil cave donor figures, in coats with lapels, Tarim Basin.
Does anyone know more about the attendants hats?

I've seen it in E. Esin, "Tabari's Report on the Warfare with the Tiirgis and the Testimony of Eighth Century Central Asian Art," Central Asiatic Journal 17.1-4 (1973), dated as 7th-9th centuries.

Thanks, I found it on JSTOR:

----------

All 3 figures have halos of a similar shape to the halo of the Khwarezm horseman. A few earlier Sasanian plates have circular halos: the Strelka dish, of Khusrau I with his Court, 6th century AD, the 'Yazdgard I Plate', a Sasanian King Hunting a Stag on foot and the 'Pereshchepina Plate', a mounted Sasanian King Hunting Mountain Sheep.
Halos also appear in the Eight Kings of the Relics Story, Maya Cave, Kizil, Tarim Basin, Cave of the Sixteen Sword Bearers, Kizil Caves, near Kucha, Tarim Basin (halos as a dark circlular outline) and on a horseman and camel-rider from Dandan-Uiliq at Khotan, Tarim Basin and others. These include a lot of Bhudist influence.
'Nimbus' can be used instead of 'halo' but I'm not sure what the plural is. I haven't noticed any halos on bowls with figures from Nishapur, Kurasan, Iran, 9th-10th centuries, Saffarid-Samanid period.

So the nimbus-distribution, like the coat-lapels, probably fits better with an earlier date than C11th?

Well, one match of nimbus is probably not enough to say.

I don't have much from the 11th century for the area.
The Wall paintings from one of the Ghaznavid palaces at Laškarī Bāzār in central Afghanistan, have lapels, but, are without heads except one with a soft headdress resembling a turban in a wall painting from room IV, which may have a nimbus.

Emel Esin doesn't say much about the plate, it is used an example of a Turkish plate for when Tabari reports silver plates captured from the Turks in the 8th century. Emel would have been attracted by a dating of the plate to the 8th-9th century (perhaps by Pugacenkova & Rempel, 1965, who are given as the image source) so any such plate would have done as well.

I have received a couple of replies about the attendants' hats.
A hat with similarities is on a bowl with a poetic recitation, Seljuk, 1187AD, Kashan, Iran. Los Angeles County Museum of Art
Many Seljuk illustrations have people with a nimbus (with the exception of al-Sufi manuscripts)
