ABSTRACT
Several original citations, rather than their interpretations or translations, illustrate importance and complexity of the nature, of the meaning, of the sense, and of the characteristics of time. They illustrate how long and from which particular points of view time has been studied, and why it has been a challenging notion and phenomenon to explain. They illustrate also the difficulty, practical impossibility, to collect, or at least to review, in one work all what was written about time. Hence, what follows does not pretend to be a review, but just to be an illustrative introduction.
