In studying history we come across what men were and did, and it helps us understand what we can be and do. Thus, history is the science of the past and the present, but the study of the past and the understanding of the present do not happen in a perfect way, as we do not have the power to return to the past and it does not repeat itself. For this reason, the past has to be “recreated”, taking into account the changes that have occurred over time. Information collected in the past will not serve the present if it is not recreated, questioned, understood and interpreted.
