One of our talented dial makers has carved a sundial in Portland stone
which is a white limestone. It carries the motto ALBO LAPILLO NOTARE
DIEM which, I am told, means to mark your day with a white stone. This
is from the concept that the Romans counted good days on a white stone
and bad days on black ones.
I have not come across this before. Perhaps some of our classical
scholars can throw some more light on this (if you will pardon the
pun).
