Img.535 from Seismograph (#E1d)

Img.535 (#E1d) Sensational ancient "artefact" shaped as a replica of the "Zhang Heng Seismograph". The pattern on this replica seems to indicate that it may originate from the Western Zhou period (1100 BC to 770 BC). If this origins would turn to be true, then it could mean, that the "Zhang Heng Seismograph" could even be over 1000 years older than it is currently believed. Unfortunately, many details of this "artefact" seems to indicate, that it is just one of these skilful fabrications prepared in present times.
