Background:
The Atwood machine (or Atwoods machine) was invented in 1784 by the English mathematician George Atwood as a laboratory experiment to verify the mechanical laws of motion with constant acceleration. Atwoods machine is a common classroom demonstration used to illustrate principles of classical mechanics.
The ideal Atwood machine consists of two objects of mass m1 and m2, connected by an inextensible massless string over an ideal massless pulley.
Both masses experience uniform acceleration. When m1 = m2, the machine is in neutral equilibrium regardless of the position of the weights.
Hall, William Henry
Hall was responsible for a significant publication in the middle of the 18th century
The new royal encyclopedia; or, complete modern universal dictionary of arts and sciences on a new and improved plan . containing a digest and display of the whole theory and practice of the liberal and mechanical arts comprising a general repository of ancient and modern literature . including all the material information that is contained in Chamber s Cyclopedia, the Encyclopædia Britannica, and the French Encyclopædie .
first published in 1788 going into many re-issues over the next 50 years.
The three volume set contained 153 copper-plate prints and maps, including some folding maps. Contained many brief encyclopedic entries in alphabetical orders plus longer, mainly illustrated, sections (systems or treatises) on a variety of subjects: Aerology; Aerostation (hot air balloons); Agriculture; Algebra; Amphibiology; Anatomy; Annuities; Architecture; Arithmetic; Astronomy (includes plates of telescopes); Book-Keeping; Botany; Brewing; Chronology; Chymistry; Comparative Anatomy; Concology; Dialling; Distillation; Drawing; Earth; Earthquakes; Electricity; Entomology; Farriery; Fencing; Fluxions; Fortification; Gardening; Geography (this section includes six folding maps); Geometry; Globes; Grammar; Heraldry; Hydrostatics and Hydraulics (one plate included a diving bell); Icthyology; Knighthood; Logic; Mammalia (included a plate showing whales); Mechanics; Medicine; Mensuration and Gauging; Miscroscopic Apparatus (microscopes); Midwifery; Military Affairs; Music; Natural History; Naval Affairs; Navigation (includes a folding map showing Cooks voyages); Optics; Oratory; Ornithology; Peerage; Perspective; Pneumatics; Projectiles; Steam Engines; Surgery; Surveying; Trigonometry; Vermeology; Volcanos; and War. Hard to find a complete set, as many have been broken up for their handsome copper plate engravings and maps.
What is an Antique Map
The word Antique in the traditional sense refers to an item that is more than a hundred years old. In the past maps were sold in two forms, as a single sheet (broadsheet) or bound in an atlas or book. The majority of antique maps for sale today come from books or atlases and have survived due to the protection offered by the hardback covers.
When considering a purchase
The first thing to determine when staring a collection or purchasing an item, is what is important to you. Most collectors prefer to build their collections around a theme. You may decide to collect maps from one region or country, charting its development through time. Similarly you could collect maps of one particular period in time, by type (i.e. sea or celestial charts) or by cartographer. The collector might also want to consider the theme of cartographical misconceptions such as California as an island or Australia as Terra Australis or the Great Southern Land.
The subject is so wide that any would-be-collector has almost endless possibilities to find his own little niche within the field, and thereby build a rewarding collection.
Starting a collection & pricing
Pricing is based on a number of different factors, the most important of which is regional. In any series of maps the most valuable are usually the World Map and the America/North America. The World because it is usually the most decorative and America because it has the strongest regional market. Other factors that come into play re: price is rarity, age, size, historical importance, decorative value (colour) and overall condition and quality of paper it is printed on.
As specialised dealers, we frequently work with first time map buyers who are just starting their collection. Guiding new collectors on their first antique map purchase and helping new collectors to focus their interests is one of the most rewarding aspects of being an rare map dealer. So please do not hesitate to contact us and we will be happy to help with any questions you may have.
