Did you ever carry a cross? Those suckers are heavy. In many common depictions, Jesus carried, or dragged the whole cross. This is unlikely; a cross would tip the scales at over 300 pounds. Even had The Man not been whipped and fitted with the thorny crown, it is still quite unlikely that he would have been able to convey something of that immense weight. More likely, as was the tradition, Jesus carried only the crossbeam, which itself would weigh about 100 pounds, still quite a load.
