This chair is going under the hammer at Frank Marshall in Cheshire and the catalogue description reads:
A Victorian oak Masonic Master's seat, Sincerity
Lodge no. 428, the triangular corniced surmount painted with an
'all-seeing eye' above the verse 'VIDE AVDI TACE', above recessed
panelled back and seat, flanked on either side by column support, total
width approx. 145cm, total height approx. 244cm
NB - This seat belonged to The Lodge of Sincerity no. 428 which was
formed in Northwich in 1835. Many people have sat in this seat
including Sir John Brunner, founder of ICI. The Lodge has now moved
from The Victoria Club to a Golf Club and the seat is too large for The
Golf Club.
