<p>Basic abstract equal-armed cross design with circle at center and surrounded by 4 nails.
</p><p>Called a "Coptic" cross by Rudolf Koch in his <i>The Book of Signs</i> (Dover); may not be prominent in Coptic Christian symbolism in this form.
</p>
Apparently sometimes the arms of the cross extend through the circle (dividing it into four quadrants).
