The yalu ibex is the same as antelope:
BEAST -- Antelope
"An antelope vs. an ibex] According to Franklyn & Tanner (Encyclopaedic Dictionary of Heraldry, p. 179), "the heraldic ibex is indistinguishable from the heraldic antelope and may even be merely an alternative term." [Thus there is not a CD between them] (Alaric Liutpold von Steinman, September, 1992, pg. 37)".
The de Bohun antelope went west from Brittany in 11th cent. It has swivelling horns:
Thus the Assyrian sacred goat is yale of Tudors. The Royal Welch Fusiliers have a ritual on 1 March where a "most handsome boy" (girl?) rides the regimental goat around the feast-table, to traditional singing. The goat has silver ornaments and used to have garlands of flowers , and leads the regiment, always being with the pioneers.
Could OBOD give an honorary title to the goat-major, as a symbol of druidism?
