I had such high hopes for this one. I was going to have it translated into 16th cen. Castillian with a Latin attestation, but the scribe was unwilling to play ball with my "overly complicated" ideas. So I put together this out of my own head based on extensive reading of 16th cen. English sources.
Sorry +Patrick Panico . I promise Castillian for your knighting or your Pelican. :-)
Wherefore we find it just, right, fitting, noble, behoveful and necessary to constitute within our Realm the Order of Defence; and wherefore our subject Pascual del Mar has, by his various deeds at arms and through his studies of the mysteries of the rapier as practiced by our cousins of Spain, caused himself to be possessed of such repute, name and worth as any good and notable man could wish for himself; therefore do we, Darius Rex and Etheldreda Regina, invest, create and endow the said Pascual as a Master of Defence, with all privileges, liberties, honors, and appurtenances attaching thereto, and instruct that he shall bear the same as freely, tranquilly, fully, wholly, honorably, well and in peace, without impediment, revocation or obstacle whatsoever, as any Peer of the Realm; and we do further invest him and his heirs males with Arms by letters patents in the form following: Per bend gules and azure, two hammerhead sharks naiant in annulo argent; and we do further charge the said Pascual to bear hereafter on his person at all times hereafter and henceforward the ensigns and signacles of the Order of Defence, that he may bring honor and renown upon the Order and our Realm. At Glenn Linn, upon 4 July, in the fiftieth year of the Society.
