I've been to Newburyport many times, but I have never seen this stone. The folks over at A Very Grave Matter don't have a picture of it either, which leads me to believe that it may no longer exist. If that's true, it's too bad — it looks like a beauty.
This picture is from the Farber Collection. Its low quality suggests that the photgraph was not taken specifically for the Farber Collection — it may be an older picture that was included because the stone was damaged or destroyed.
Sacred to the Memory
MR. RICHARD TAPPAN,
a worthy ruling Elder of the
presbyterian Church, in this Town:
who finished a well tried Life,
of godliness and honesty,
his flight to his Redeemer's arms
gently laid his hoary Head to rest
beneath this mournful Turf
on the 27th of April in the Year
of our Lord 1785 AEtat .77.
this monumental Stone
by his weeping Widow and Children
