COMPOUND MICROSCOPE Zacharias Janssen was a Dutch lens-maker who invented the first compound microscope in 1595 (a compound microscope is one which has more than one lens). His microscope consisted of two tudes that slid within one another, and had a lens at each end. The microscope was focused by sliding the tubes. The lens in the eyepiece was bi-convex (bulging outwards on both sides), and the lens of the far end (the objective lens) was plano-convex (flat on one side and bulging outwards on the other side). This advanced microscope had a 3 to 9 times power of magnification. Zacharias Janssen's father Hans may have helped him build the microscope. |

Galileo Galilei (1564-1642) was an Italian mathematician, astronomer, and physicist. Galileo found that the speed at which bodies fall does not depend on their weight. Galileo did extensive experimentation with pendulums, finding that they nearly return to the height at which they were released, that different pendulums have different periods (independent of bob weight and amplitude), and that the square of the period varies directly with the pendulum's length. Galileo was the first person to use a telescope to observe the skies (in 1609), after hearing about Hans Lippershey's newly-invented telescope. Galileo discovered the rings of Saturn (1610), was the first to see the four moons of Jupiter (1610), observed the phases of Venus, studied sunspots, and discovered many other important phenomena. In 1593 Galileo invented the thermometer. After publishing the many discoveries he made using his telescope, including the motion of the Earth around the Sun (the Copernican system), Galileo was accused of heresy by the Inquisition (in 1633). |
Martin Behaim (1459-1537) was a German mapmaker, navigator, and merchant who made the earliest globe, called the "Nürnberg Terrestrial Globe". It was made during the years 1490-1492; the painter Georg Glockendon helped in the project. Behaim had previously sailed to Portugal as a merchant (in 1480). He had advised King John II on matters concerning navigation. He accompanied the Portuguese explorer Diogo Cam (Cão) on a 1485-1486 voyage to the coast of West Africa; during this trip, the mouth of the Congo River was discovered. After returning to Nürnberg in 1490, Behaim began construction of his globe (which was very inaccurate as compared to other maps from that time, even in the areas in which Behaim had sailed). It was once thought that Behaim's maps might have influenced Columbus and Magellan; this is now discounted. Behaim may have also developed an astrolabe. Behaim's globe is now in the German National Museum in Nürnberg. |

MICROSCOPE Robert Hooke used an early microscope to observe slices of cork (bark from the oak tree) using a 30X power compound microscope. He published his observations in "Microgphia" in 1665. In 1673, Antony van Leeuwenhoek discovered bacteria, free-living and parasitic microscopic protists, sperm cells, blood cells, etc., using a 300X power single lens microscope.

PENCIL In 1795, the Nicholas Jacques Conte (a French officer in Napoleon's army) patented the modern method of kiln-firing powdered graphite with clay to make pencils of any desired hardness.

The Thermometer was invented by Galileo Galilei in 1593. His thermometer consisted of water in a glass bulb; the water moved up and down the bulb as the temperature changed. |

Patchwork Merchant Mercenaries had its humble beginnings as an idea of a few artisans and craftsmen who enjoy performing with live steel fighting. As well as a patchwork quilt tent canvas. Most had prior military experience hence the name.
Patchwork Merchant Mercenaries.
Vendertainers that brought many things to a show and are know for helping out where ever they can.
As well as being a place where the older hand made items could be found made by them and enjoyed by all.
We expanded over the years to become well known at what we do. Now we represent over 100 artisans and craftsman that are well known in their venues and some just starting out. Some of their works have been premiered in TV, stage and movies on a regular basis.
Specializing in Medieval, Goth , Stage Film, BDFSM and Practitioner.
Patchwork Merchant Mercenaries a Dept of, Ask For IT was started by artists and former military veterans, and sword fighters, representing over 100 artisans, one who made his living traveling from fair to festival vending medieval wares. The majority of his customers are re-enactors, SCAdians and the like, looking to build their kit with period clothing, feast gear, adornments, etc.
Likewise, it is typical for these history-lovers to peruse the tent (aka mobile store front) and, upon finding something that pleases the eye, ask "Is this period?"
A deceitful query!! This is not a yes or no question. One must have a damn good understanding of European history (at least) from the fall of Rome to the mid-1600's to properly answer. Taking into account, also, the culture in which the querent is dressed is vitally important. You see, though it may be well within medieval period, it would be strange to see a Viking wearing a Caftan...or is it?
After a festival's time of answering weighty questions such as these, I'd sleep like a log! Only a mad man could possibly remember the place and time for each piece of kitchen ware, weaponry, cloth, and chain within a span of 1,000 years!! Surely there must be an easier way, a place where he could post all this knowledge...
Traveling Within The World is meant to be such a place. A place for all of these artists to keep in touch and directly interact with their fellow geeks and re-enactment hobbyists, their clientele.
