This is one of the Crowcombe, Somerset, bench-ends carved in 1534 -- [for the undoubted Parisian Horae source of the small square panel bottom left -- SEE BELOW]. Given that other motifs at Crowcombe derive from 'my' Parisian Horae metal-cuts, I believe this gastrocephalic dragon does too! [SEE ADJACENT]
This is where we came ion, or rather, the point at which I felt I'd reached 'critical mass' and where these disproportionately influential yet almost unknown motifs merited their own board! Detaul of the letter Q from one of the early 16C alphabets in the Macclesfield Alphabet Book
gastrocephalic dragon pursues putto -- detail from the lower margin of Pierpont Morgan Library, MS M 463, f.85r., a late 15C French breviary (?Toulouse, c.1495) -- I suggest both this and the snail-riding-dragon motifs derive from the adjacent metal-cut ornaments which decorate the borders of Books of Hours printed in Paris c.1500
This may be a derivation too far for the more sceptical of my art historical brethren/sistren but -- giiven what I regard as the proven derivation of grotesques 3 and 4 of this panel [SEE PRECEDING], then I am bold to sugges that this is my pitiless puttiless [see what I did there?] 'gastrocephalic' dragon!
