X-Ray Image of a Winghead SharK 



The distinctive form of a winghead shark (Eusphyra blochii) is revealed by an X-ray image. The Winghead Shark, one of about ten species of hammerhead sharks, has its eyes set at the tips of its wide, T-shaped head, giving it superb binocular vision.

Venetian Polaxe for the Foot Tournament 

  • Dated: first quarter of the 16th century
  • Culture: Italian
  • Measurements: head 43.3 cm. Overall length 196 cm

This “ascia da fante” has a head of characteristic two-part construction secured centrally by a transverse bolt with short pyramidal heads, with sharply tapering hollow-triangular spike on a moulded two-stage neck. The latter is extending to form a pair of straps each retained by six nails and fitted over the common neck of the axe-blade and pean.

The juncture is impaled by a transverse bolt, with symmetrical axe-blade with convex edge and a strongly cusped back edges. There’s a pierced quatrefoil inlaid with the maker’s mark, a leaping stag, and with moulded triangular pean (fur resembling ermine but with gold spots on a black ground) with a rectangular face cut with a diamond-pointed rusticated pattern over its surface.

There are three comparable examples are in the former armoury of The Council of Ten in the Palazzo Ducale, Venice (CX 1450, CX 1458 and A 897). For the first two see BOCCIA, Lionello G. & COELHO, Eduardo T., "Armi Bianche Italiane", Milan 1975, nos. 268 and 269, p.358. for the third see FRANZOI, Umberto, "L’Armeria del Palazzo Ducale a Venezia", Dosson (Treviso) 1990, no.321, pp. 113 and 195,fig. 108.
