LETTER # JOSEPH C. WALKER, 44; MR.LA. 
&e. from the Right Honourable W. CON Y NGHAM, Treafurer 
to the Royal Irifh Academy, being an APPENDIX fo his 
MEMOIRE on the THEATRE of SAGUNTUM. 
SIR, Dusuin, Fesrvary 4th, 1790. 
Since I had the honour of laying before the Academy the 
Plans of the Theatre of Saguntum, I have feen that of the 
Theatre at Athens in the fecond volume of Mr. Stewart’s Defigns, 
and, as he has unfuccefsfully attempted to afcertain the conftruc- 
tion according to the rules of Vitruvius for Grecian, Theatres, by 
infcribing three fquares in a circle a tangent to whofe diameter 
determines the front of the Scena, I beg to add to my former 
plans that of the Athenian Theatre, adapted to the principle of 
infcribing four triangles as reprefented in the plan of Saguntum, 
and fo exadtly does it correfpond with the latter, as far as depen- - 
dance may be had on the plan of Mr. Stewart, fo remarkably 
coincident is the diftribution and even meafurement of every 
part,
