One of the great technical achievements that revolutionized the idea of time and space, opening a new era in the history of communication, is telegraphy. It is based on the transmission of electrical signals through a cable over long distances, allowing people to communicate instantly. The telegraph spread very quickly and a network of wires stretched around the world.
In 1837, the American painter and physicist Samuel Morse invented the first electromagnetic device for telegraphy, patented in 1840. To send messages by wire, Morse developed in 1838 a simple code of dots and dashes, which represented the letters of the alphabet, known as "Morse code ".
Both Morse code and the telegraph machine were improved over time, with the telegraph becoming the most widespread system of communication and information transmission for more than a century, until the advent of the Internet. The telegraph system consisted of a series of stations repeaters along the transmission line route. Each station had an operator who received and transmitted messages by telegraph. The Morse machine transmitted about 25 words per minute, which were recorded in code on a paper tape. The operator in charge of transmitting the message would decode it and write it on paper using a special typewriter.
In Bessarabia, the telegraph entered in 1860: on April 8, the Bender telegraph station began its activity, and on April 24, the one in Chisinau, following the construction of the first Odesa-Chisinau-Leova telegraph line. Currently, telegraph services have been discontinued. The only ones who still use coded communication are radio amateurs.
The Morse telegraph machine shown comes from the Osinoostrovsky electrotechnical plant, Soviet Union, and dates back to 1934. The exhibit was restored by Mihail Culașco.
The collection of Heraclian stamps from the site of Košary, Odessa region, Ukraine
Tyragetia, serie nouă, vol. II [XVII], nr. 1, Arheologie. Istorie Antică
The article continues the publication of a series of ceramic amphora stamps from the ancient complex of Koshary. In this publication there are presented the stamps of Heraclea Pontica, one of the famous centers of producers and suppliers of goods in the Black Sea coast. The analysis of more than 40 stamps of this South-Pontic center revealed not only the time of trade relations in these areas in general (the end of the 5th – the beginning of 4th centuries B. C. – the first third of the 3rd century B. C.), but also in the given settlement in particular, the time of the most active trade of the Koshary settlement with Heraclea (the second half of the 4th – the beginning of the 3rd centuries B. C.). Among this group of stamps there is an unknown specimen of a manufacturer’s stamp seemingly dated from the last years of the Heraclea stamping.
