Annapolis Maryland USA Self-Orienting Dial 174
4'x4' Bronze & Brass 4' Dial plate is elaborately engraved bronze with hour and date lines. Self-orienting dial. Locate line for the date; rotate dial until shadow tip touches that line. Read time from intersection of the shadow's tip and the time line radiating from dial center. Gnomon is a model of a naval missile, resting on an anchor. A ship's binnacle supports rotating sundial plate. As of July, 2012 the missile gnomon is missing.

Annapolis Maryland USA Armillary Dial 765
A bronze armillary dial with meridian, horizon and equatorial rings on a concrete pedestal. Dial is located in Government House residence and requires a tour of the property for access.
 
 
Baltimore Maryland USA Polyhedral Dial 91
Bronze on stone. Renovated 1904 and again in 1994 (by George McDowell.). It is a 17-facet hemispherical compendium dial. Has facets calibrated for local solar time for Baltimore, Jeddo [Tokyo], Honolulu, Sitka, Pitcairn Islands, San Francisco, Cape Cod, Rio Jancito, London, Fernano Po, Cape Town, Jerusalem, and Calcutta. Has a polar and vertical dial for Baltimore time. Built in 1892 by Peter Hamilton, 19th C Baltimore stonecutter, became president of the company which supplied granite for the Library of Congress building. Repaired and reset in 1904. Reworked in 1993. The original pedestal remains, consisting of a stone pillar carved to resemble the trunk of a tree.
 
 
Baltimore Maryland USA Vertical Dial 243
18 x29 inch vertical dial. Solar noon analemma, equinox and solstice lines, horizontal lines, line showing approx shadow lengths on April 15 and Aug 31. Lines sandblasted into veined white Carrera marble. Dial is calibrated for EDT. AM hours indicated by shadow of stile's western edge, PM, by shadow of its eastern edge. When shadow tip is bisected by appropriate seasonal segment of the line of the analemma, it is 1:06:35 PM.
 
 
Baltimore Maryland USA Horizontal Dial 323
Nice horizontal dial sitting on a 6 x 4 foot stone pedestal. The dial itself is 5 foot in diameter with a 2.5 foot gnomon of open-work bronze. The lines, numerals and lettering of the dial face are so finely done that one cannot tell whether the dial plate was made of cast stone or was carved by an extraordinarily skilled mason. The gnomon, unfortunately, is situated incorrectly on the dial face. The point at which the stile diverges from the dial plate is about five inches south of the correct point where the hour lines converge.
 
 
Baltimore Maryland USA Horizontal Dial 324
A horizontal dial 36 inches in diameter, made of bronze, sitting on an irregular pentagonal block of granite. Gnomon missing. Calibrated to read local solar time, and has a graph of the Equation of Time to correct readings to standard time.
 
 
Baltimore Maryland USA Horizontal Dial 325
A 12 inch diameter horizontal bronze dial. A wire is stretched from the dial's center, which is decorated as a cluster of flowers, to the beak of a bird perched on the rim of the dial plate, forming the gnomon at proper angle. The bird is apparently the 'early bird' eating the worm (gnomon). The dial plate itself has hour lines and Roman numerals from 5 am to 7 pm. Dial sits atop a cast concrete post with octagonal top.
 
 
Baltimore Maryland USA Horizontal Dial 326
'Very bad small dial on a beautiful stone pedestal. The engraving on the base states that it was erected in 1908. At some point the dial face went missing. A new dial was installed sometime before 1966. It is doubtful that the existing dial is a replica of the original. The stylistic differences between the design of the pedestal and the design of the new dial which sits atop it are apparent.' (McDowell)
 
 
Baltimore Maryland USA Equatorial Dial 327
The dial is a partial cylinder held upright at the proper angle by four ornate pillars. The gnomon is a wire stretched between another pillar at the south edge and the mouth of an eagle mounted on another pillar at the north edge. On the wire is a bead, the shadow of which falls on the cylindrical plate. The cylindrical plate has an analemma for each daylight hour of standard time.' (McDowell) One of three known to be made in this design. Another dial of this design, once in front of the Physical Laboratory at Northwestern University, was placed at a private residence in New Hampshire in 1973, Evanston, IL.
