补充资料:雷尼耶,H.de
法国诗人。贵族家庭出身。他的精雕细琢的诗和散文都表现温柔、委婉和朦胧的意境,受到巴黎沙龙中的绅士淑女们的赞赏。他的第一部诗集《明日》(1885)反映了明显的帕尔纳斯派的特色。稍后,诗集《古老的和传奇的诗歌》(1887~1890)和《恍如梦中》(1892)表明他是当时象征派的主要人物。但在发表诗集《泥土勋章》(1900)和《生翅膀的凉鞋》(1906)后,他已脱离象征派而回到古典的诗歌传统方面。雷尼耶的重要作品还有诗集《田园和神圣的游戏》(1897)、《水城》、《时间的镜子》(1911)以及小说《双重的情妇》(1900)、《妙趣横生》(1902)等。
雷尼耶于1911年被选为法兰西学院院士。
