 These probably date from around 1875 and were made by the firm of Lyon, Cottier & Co of Sydney, the leading exponents of stained glass in Australia of their time.Lyon & Cottier commenced trading in 1873, hence the stained glass works are a later addition to the house possibly dating from the time of Gordon's involvement in construction of St. Andrew's College which contains much of their work.The panels show the influences of Pre-Raphaelitism and the design was also used in the depiction of the seasons, but here used in the common motif of wealth and abundance.
