It’s a remarkable co-incidence – and nothing but a co-incidence – that 1 inch is almost exactly 2.5 centimetres (actually 1 inch = 25.400mm, 1cm = 0.3937 inches); so that if you draw a linear scale of years of {e.g.} up to 512 years, in which 1 inch represents 64 years, on the same scale the centuries may be drawn for reference so that each century is represented by 4cm.

Perhaps this should be warning against drawing too many and wide conclusions from co-incidences. But I am incorrigible.
