Treasures from Dalkey mansion include imitation-Japanese furniture

China’s top exports in 2020 were broadcasting equipment, computers and circuits, according to the Observation of Economic Complexity (OEC). But back in the 17th century it was a far more opulent affair. The taste for all things oriental started when tea drinking became fashionable in London and goods such as porcelain, silk, spices and lacquerware were in such demand that it outstripped supply. To keep up, English joiners decorated their work to imitate oriental lacquer, especially with a finish known as japanning; a European imitation of east Asian lacquer work.

At the forthcoming Monte Alverno sale, which will be conducted by Sotheby's in London on May 26th, the highlight of the sale is a George I japanned bureau from 1720, in the manner of John Belchier. The piece, in gilt and scarlet, has Chinese-influenced decoration, "perfectly demonstrating the two great influences on English design of the period", according to catalogue notes.

It is believed to have come from Bletchley Park in Buckinghamshire, the Victorian gothic mansion that became the principal centre of Allied code-breaking during the second World War. It was presumably acquired by Sir Herbert Leon, who owned the 581-acre estate, until it was later acquired by Sir Hugh Sinclair for the sole use by the Government Code and Cypher Schools and the Secret Intelligence Service (£150,000-£250,000/€177,500-€295,820).

The bureau is just one of almost 100 lots included in the sale as part of the private collection of Monte Alverno, the 19th century baronial style mansion on Sorrento Road in Dalkey which sold last year for €5.85 million, according to the Property Price Register. Acquired in 1993 by businessman Alphonsus O’Mara, the interiors were richly decorated with the feel of a gentleman’s club, full of fine art, leather sofas and oriental rugs.

As you would expect, a Jack B Yeats features in the collection. The City is one of several landscapes produced by the artist when he lived in Dublin and depicts the wide grandeur of College Green with a young boy in the foreground (£150,000-£250,000/€177,500-€295,820).

With clean graphics and primitive still life, William Scott’s Still Life with Orange, (£120,000-£180,000/€142,000-€212,990) reflects his challenge to academic tradition and has been described as a “negotiation between austerity and sensuality” according to catalogue notes.

Some remarkable Georgian furniture features including a pair of Irish George III satinwood demi-lune tables, attributed to James Hicks (£20,000-£25,000/€23,670-€29,580) and an Irish George II carved mahogany open armchair. The heavily ornate chair was part of furniture company Parker Knoll's collection accumulated as an educational tool for its craftsmen, so they could understand techniques and draw inspiration (£15,000-£25,000/€17,750-€29,580).
