Inescutcheon

All the quartered Arms that I meet vvith belonging to Scottiſh Families, do not exceed ſix different Coats of Arms, vvhich are marſhalled after theſe three vvays, Plain Quartering, Quartering, and Counter-quartering, of vvhich I have treated and illuſtrate by Examples, vvith their Surtouts and Ineſcutcheons.

[A]n Ineſcutcheon is properly the Charge of a Shield, and born vvithin a 'Scutcheon or Shield, […]

When only one escutcheon is borne as a charge, it is now generally termed an in'''escutcheon, but in the early rolls there is no such distinction.

Within a blue garter inscribed "Great Northern Railway Ireland" is a shield, on which are marshalled the arms of the principal towns in the company's area. The shield is divided quarterly with the arms of Dublin in the first quarter, Londonderry in the second quarter, Enniskillen in the third, and Belfast in the fourth; and overall is a gold inescutcheon (a small shield placed in the centre of the large shield) charged with the red left hand of Ulster.

When he became titular bishop of Hippo and auxiliary bishop of Boston, he added an inescutcheon or small shield in the center of his shield bearing a gold heart inflamed pierced by an arrow and on a blue field. Since titular bishops do not impale their personal arms with those of the see, this was a convenient reference to his titular see.
