So it seems that Old English had about twenty different verbs for the act of sparkling/glittering:
ablican, ascimian, bliccettan, blyscan, brodian, brogdettan, glitenian, (ge)lixan, ræscan, ræscettan, scimian, scinefrian, spircan, tytan, scimian, blican, glisnian, spearcian, twinclian…
Say what you will, but I find there is something appealing in a language with so much sparkle to it…
And yes – I do love the Historical Thesaurus.
