Horatio Walter Lonsdale

Horatio Walter Lonsdale (1846-1919) was an English painter and designer. He established a long partnership with the architect William Burges, working with him on many of his major commissions, including Saint Fin Barre's Cathedral, Cardiff Castle, Castell Coch and Burges's Yorkshire churches. Lonsdale worked so closely with Burges's, particularly in the design of stained glass, that "it is often hard to say how much of any given design is Burges's and how much is (Lonsdale's) — designs were often initialled by both." He also designed the zodiac windows and celestial ceiling at Mount Stuart House.
