"Unicorn ermine?" Topic

I'm painting a retinue for Thomas grey, Marquess of Dorset who's symbol is a "unicorn ermine". What does that mean? What does it look like?

Ermine is a heraldic fur so I would assume a unicorn in that colour

I suppose a white unicorn with a few black dots at any scale.

Heraldic nuances vary with time so how a contemporary artist would have depicted a unicorn ermine would depend on the date.

If I remember correctly the unicorn is one of the supporters so would be in 'rampant' pose, white with a few black ermine spots on its body and upper thighs. Try and find a contemporary illustration – it may also be collared and chained, that was quite common for unicorn supporters.

A modern version of "a unicorn ermine" can be seen as the supporters of East Retford Council's arms at link

According to an old Osprey ( link ) Thos Grey's unicorn was, like the Retford ones, "armed, unguled, maned and tufted or" – the horn, hooves, mane, and the tuft on the tail were gold/yellow (but no collar is mentioned).

Sorry, I should have mentioned this was for the War of the Roses. The link to the Osprey book didn't work but as I have a copy of the originail book perhaps you could point to a page number? Thanks :)

The google preview doesn't show the page numbers in this cae. It is the list of heraldry and some livery of certain English nobles from 1300 to 1550. It is quite a long list over a couple of pages so would stand out with a flick through.
