The significance of the handshake motif in Classical funerary art

Abstract: The handshake motif was widely used by Greek, Etruscan and Roman artists in both funerary and nonfunerary contexts. This article aims to give a general survey of the motif from Archaic Greece to the late Roman Empire, looking especially at the continuity of its use. The principal aim is to elucidate its meaning in funerary contexts, but to do so its appearance in non-funerary contexts is also considered. Throughout the period considered the handshake had a multiplicity of associations which were exploited by the artists to create an ambiguous meaning. The themes of meeting and parting were persistently associated with the handshake (especially parting from relatives at death, and reunion with ancestors in the Underworld), but various other themes were also related to it, especially marriage, an association that was first made in Greek art but which only became dominant in the later Empire. The handshake motif often appears today in press photographs and commercial logos as a symbolic gesture. Since we may in fact shake hands on a number of rather different occasions-when meeting or welcoming someone, parting from them and making our farewells, or when we have come to an agreement and wish to express mutual trust-the exact connotations of the handshake in a particular picture are not immediately obvious. Despite this inherent ambiguity the handshake remains a potent symbol. The same ambiguity would seem to have existed in the classical world, although there, in addition to parting, meeting and agreement, the motif also seems to have had an association with marriage. The present study examines the use of the handshake gesture in a wide range of classical art, Greek, Etruscan and Roman, concentrating on funerary art but with some consideration of the appearance of the motif in nonfunerary contexts. Previous scholars have looked at the meaning of the motif in individual categories of funerary monuments, but have not attempted to trace the history of the handshake motif throughout the classical period. As a result they have arrived at different interpretations of the motif at different periods.' The handshake motif was, however, used with a degree of continuity which suggests that, despite changes in emphasis, there was a general meaning which underlies all variations and which continued to be understood. My aim is to re-examine the various contexts in which the motif was used, and to elucidate the associations and meanings it may have had. DEXIOSIS IN GREEK ART The best-known and most common use of the handshake motif (dexiosis) in Greek art is on the Athenian grave stelai of the Classical period. However, sporadic scenes with a pair of figures shaking han s had occurred earlier in other, non-funerary,

Standard digital interface device

Abstract: PURPOSE:To easily detect a hand map by displaying the incompletion of a handshake when a handshake processing time exceeds a set value. CONSTITUTION:A control element 1 is constituted as a processor which codes messages of the standard digital interface 2 and realizes an interface function, and a one-chip microcomputer which incorporates I/O ports for controlling the handshake and a timer for time-out setting is used. A master CPU2 and dedicated bus transceivers 3 and 4 are connected to this control element 1, and the bus of the standard digital interface is connected to those dedicated bus drivers 3 and 4. The timer in the control element 1 is started at the start of a source handshake or acceptor handshake, and the incompletion of the handshake is displayed when the handshake processing time exceeds the set time of the timer.

Handshake simulation system for reception

Abstract: PURPOSE:To attain the simulation proper to various handshake systems by connecting a transmitter to the handshake simulation system for reception to execute the test for the transmission function of the transmitter. CONSTITUTION:A signal representing the state for data transmission from the transmitter is inputted to a polarity selection circuit 4 via a line 3 of a handshake simulation circuit 2, a switch 9 is conducted so as to attain the positive logic and the result is led to a line 10. Then the result is fed to a control circuit 11 where the response time and pulse width are set to a desired value by the combination of from a dip switch 19 and clock pulses from a clock pulse generating circuit 15. Thus, the simulation leading the signal representing the state for the reception is attained to the transmitter in response to the signal representing the state for the data transmission from the transmitter.

Handshake simulation system for transmission

Abstract: PURPOSE:To attain the simulation suitable for various handshake systems by connecting a receiver to a handshake simulation device for transmission to perform the test for reception function of the receiver. CONSTITUTION:A signal representing the state for data transmission from the receiver is inputted to a polarity selection circuit 4 via line 3 of a handshake simulation circuit 2, a switch 9 is conductive, the state is brought into positive logic, which is led to a line 10. Then it is fed to a control circuit 11, where the response time and pulse width are set to a desired value depending on the combination of dip switches 19 and a clock pulse from a clock pulse generating circuit 15. Thus, the simulation leading the signal representing the state for transmission to the receiver is attained in response to a signal representing the state for data reception from the receiver.
