It’s What’s on the Reverse Side

 

QUESTION: Years ago, I purchased a banjo clock with an intricate scene painted on the clock glass. At several recent antique shows, I’ve noticed several other reverse paintings from the early 19th century. What is the origin of reverse painting glass? And when was the technique at its peak?

ANSWER: Reverse painting is done on the backside of the glass and has been done since ancient times. Though there are only some crude artifacts, art historians believe the process dates back to Egypt in 4 C.E.

During the Middle Ages in the 13th century, the art technique appeared in Italy. Shortly thereafter, the French and English also learn of this art-form.  By the 16th century Renaissance, reverse painting reached its peak. To meet the growing demand, glass artists on the Island of Murano in the Venetian Lagoon widely produced small reverse glass paintings to decorate church alters and for other religious purposes. Gradually they began to paint larger landscapes, portraits, and more, making Venice a center of the technique.  

Beginning in the mid 18th century, painting on glass became preferred by the Church and the nobles throughout Central Europe. By the early to mid 19th century, watchmakers used reverse painting for dials on their watches.

Reverse glass painting had been practiced in Europe for several centuries. In France, Rococo decorative arts influenced it. In Italy and Switzerland, landscapes and small figures dominated reverse glass painting. Persian miniatures inspired it in India, Syria, and Iran, drawing attention to Islamic religious themes. German, Italian, and Spanish artists specialized in allegories, regional costumes, and hunting scenes while iconographic painting influenced the technique in Eastern Europe. 

In America, reverse painting enjoyed its greatest popularity during the Federalist Period of the early 19th century. Old-country artisans in the colonial cities used reverse paintings to decorate clocks, mirrors and other items of the time. This art fashion reigned from about 1815 to 1850. Then, with the exception of a brief time before World War I when it enjoyed a comeback, reverse glass painting became all but extinct.

Before an artist can reverse paint on glass, all details must be known. Done with oil paint ground with shellac, varnish, or linseed oil. Often the colored pigments were back by a white ground which reflected light back through the paint and gave the painting a warm and brilliant color. The smoothness of the glass increased the painting’s richness and vibrancy. 

Not only is the painting done on the reverse side of the glass, it must be done in reverse, beginning with the finer details and ending with the background.

Subject matter was mostly religious with paintings done by peasants but also included allegorical subjects, heroes of the day, and landscapes. Many of these paintings, primitive in technique, included Vermillion red, blue, yellow. Religious scenes could be found in peasant homes. These had backgrounds embellished with floral decorations and scrolls. Early paintings had lots of gold but later ones just had accents. These primitive paintings had crude homemade wooden frames. 

During the reign of William and Mary in the 17th century, the frames of mirrors had moldings of glass painted with roses, tulips, and leaves touched with gold. Back in the 14th century, East India Traders brought courting mirrors from China. This type of painting became popular in Europe during the 18th and 19th centuries.

In the late 18th and early 19th centuries, secular subjects became popular, including portraits of women symbolical of spring, summer, fall, and winter, as well as portraits of kings and queens.

Reverse painting spread to America and was popular with the Pennsylvania German immigrants, who carried on the religious traditions. They also painted primitive portraits of famous Americans such as George Washington and Andrew Jackson. Copies of portraits of Washington by Gilbert Stuart were quite popular.

Still life was more popular than portraits in New England. Other subjects included naval battles, such as the Monitor and the Merrimac. Amateurs and itinerant artists painted these paintings, so they call into the folk art category.

One of the most common uses for reverse paintings was on clock pendulum doors. Popular subjects included a floral or fruit still life or a simple flag or eagle design.

A Question of Time

QUESTION: I have inherited a very plain tall clock made in Philadelphia. How can I tell how old it is?

ANSWER: To tell the age of a tall-case clock, or grandfather clock as it’s more commonly known, you need to first look at the dial. The early ones at first showed 24-30 hours. Owners wound them at the end of that time by pulling the driving cord down.

In the earliest clocks—those dating from the 17th to early 18th centuries—the hour circle appears in a silvered ring with a doubled circle appearing within the numeral circle.

Many old clocks have only an hour hand. Some have both an hour and a minute hand. Even though clockmakers had used minute hands since 1670, most clocks, except the most expensive ones, didn’t have them. Early tall-case clockmakers gave their hands a fine finish and often made them the most decorative part of the clock. The hour hand was often the most elaborate and the second hand, if the clock had one, was sometimes long and graceful. Later, when clockmakers introduced white dials, the hour and minute hands became even more ornate and some even had a smaller second hand.

Originally, tall-case clockmakers made their dials of metal with a matt center circle. By the mid-17th century, they added ornamentation around the edge of this matted center, engraving birds or leaves to form a border showing the days of the month. They brightly burnished this date ring as well as the rings surrounding the winding holes. Silvered dials, containing no separate circle for the hours and minutes, appeared in 1750. Instead of a matted center circle, these dials featured an engraved overall pattern in the center circle. Many early tall-case clocks also had a small separate dial showing the days of the week.

Dials remained square until the beginning of the 18th century, at which time clockmakers introduced the arched dial. Dutch clockmakers found good use for this extra space, filling it with decorative figures and animated devices such as a see-saw or a shipping rolling at sea. They also added a moon dial, thereafter common on many tall-case clocks, which displayed the phases of the moon under the dial’s arch. English clockmakers, mostly in Yorkshire, went one step further, creating a globular rotating moon dial.

Clockmakers usually only made the works of tall-case clocks. They subcontracted the making of the cases to coffin makers, who used this as supplemental income when business was slow. During the second half of the 17th century, casemakers employed walnut to build mostly plain cases. The Dutch introduced marquetry to the fronts of the clock cases, using woods of different colors and grains.  Mahogany didn’t come into general use for tall-case clocks until about 1716. At first, casemakers imported it from Spain, then after that supply ran out, from Brazil.

Before 1730, the doors of most tall-case clocks were rectangular, but around that time casemakers included an arch in them to match the arched dials. The earliest clocks didn’t open with a door. Instead, the entire hood–the top part of the clock–slid backwards revealing the works.
