对于历史研究来说,首要条件是占有资料。而资料通常分为两大类,即文献和实物。去年金秋,法国的史前史研究领域又增添了新的实物资料,那就是发现了位于马赛附近一个小海湾里的海底石窟文化。 For historical studies, the first condition is possession of information. The information is usually divided into two categories, namely literature and in-kind. In the autumn of last year, the study of prehistoric history in France added new material figures. It was the discovery of a seabed grotto culture in a small cove near Marseille.
