I hope to collect as many images as possible, so it is then clearer which styles were worn in which decade. There are so many images out there; I wish I could show them all. This batch are nice an colourful.

Whole body lion model perched on a frog mouthed helm. This one reminds me of our modern family name crest. Also, I want that red, gold and peacock patterned fabric so badly.

Wide plume of peacock feathers rising from within a crown on a helm. Another man wears a simple single width wreath of leaves over his slotted kettle helm.

Plume of shortened peacock feathers, 3 rows high, rising out of a crown which is worn over red acanthus dagged mantling, all over a bulbous barred helm and kaston brest (boxy breast plate).
The hair style worn by the kneeling lady is still present during until at least 1440. There are examples of the double buns under a net with crossed ribbons on the top of the head in the 15th C French edition of Baccaccio's Decameron. The second, smaller bumps on either side of the top of her head are not shown in Decameron, though. Interestingly, the full sleeves that are gathered into the cuff seem to come back into style in the 1470s and 80s. Maybe that is not a true statement, if looking at adjacent but different countries. One day I will have a good look at sleeves.
