First editions of two tracts offered in a single lot by Dominic Winter at South Cerney on July 22 include a cult work on alchemy by Raymundus Lullius, De Secretis Naturae , written in the 13th century but translated by Walter Hermann Ryff in Strasbourg in 1541. Lullius, also know as Ramon Lull and Raymond Lully, was a Catalan poet, novelist, theologian, inventor, medical writer, mariner and missionary, and allegedly the discoverer in 1275 of "sweet vitriol", now better known as ether; he also published major works on Christian theology, mostly involving ways to convert Muslims to Christianity. The other tract, on metals and minerals, is by a second 13th-century genius, Albertus Magnus, aka St Albert the Great or Albert of Cologne, who is seen as the greatest German philosopher and theologian of the Middle Ages. Two towering works, though not necessarily your books of choice for the beach, they are estimated at £3,000-£5,000.

They feel like doing a Highland fling at Wessex Auction Rooms near Chippenham at present, having been asked to sell a large collection of works by the Scottish artist James Paterson – including 12 signed paintings in oil or watercolour – at their specialist auction on July 9. Paterson (1854-1932) is one of the Glasgow Boys, artists from that city who trained in Paris and brought back to Scotland new ideas on social realism, and while he differed from the others in specialising in pure landscapes, that does not undermine his appeal. The pictures have come from a local source and a member of the Paterson family, and large oils such as the snow scene seen here are expected to go for up to £10,000. The smaller watercolours are estimated at £500 upwards, while there is some work not signed by the artist but attributed to him by the family. Since demand for regional art is buoyant, and Paterson went from Glasgow Boy to prominent member of the Royal Scottish Academy, who knows what will happen with some of these major works that have never been on the open market before?

Simon Chorley's sale at Prinknash Park on Thursday includes this classically Edwardian gold triple-gate bangle, set with opals and diamond divisions, which is estimated at £1,800-£2,200. Also on offer will be an attractive diamond brooch (£800-£1,200), an elegant pair of Edwardian emerald and diamond earrings (£2,000-£2,50) and an aquamarine single-stone pendant which could go as high as £1,500.

Charterhouse's auction in Sherborne on Friday offers mementoes of the World War II hero Rear Admiral Godfrey Place, not least his Victoria Cross medal ribbon. He was just 22 in September 1943 when he took one of two Midget Submarines more than 1,000 miles through enemy waters to Norway and helped plant charges on the German battleship Tirpitz that put her out of action for months. His VC is on display at the Imperial War Museum and it comes as something of a surprise to learn that the ribbon, complete with miniature VC, is estimated at no more than £100-£200, together with other memorabilia including his bosun's whistle from the Royal Naval College at Dartmouth and a signed photograph of the Queen and Prince Philip.

Wessex Auction Rooms' general sale near Chippenham a week today includes this Poole Pottery vase, 16ins tall and dating from about the early Seventies. It's from the Delphis range, designed by Carol Cutler, and though it has a price guide of £50-£80, a similar one sold last year for £320.

Flower Market, Munich, an oil on board by early 20th-century London artist Adrian Paul Allinson, goes into Cotswold Auction Rooms' modern art and design sale in Cheltenham on July 7 with an estimate of £600-£900. It is a comparatively early work; he gave up studying medicine and switched to art in 1910, when he was good enough to go to the Slade, and it was from there that he went on to Paris and Munich. At ease in the London artistic scene, his posts included stage designer for the Beecham opera company and art master at the Westminster Technical Institute, while he became a member of the London Group in 1914. Posters for British Railways and covers for Coterie magazine followed. He also exhibited at the Royal Academy, New English Arts Club and Fine Art Society, which put on a retrospective show in 1984.

A strong oriental section at Simon Chorley's sale at Prinknash Abbey on Thursday includes these three items from the Tang dynasty of the years 618 to 907: a pottery figure of a Bactrian camel (£60-£80); a painted pottery figure of a polo player astride a horse (£100-£150); and a pottery model of a horse's head (£40-£60).
