据《百度 百科》资料，“契（閼伯）”也是中国4400多年前的一位重要人物，他正是商朝的祖先，而且是古代的伟大天文学家：
契（xiè），一作卨，子姓，河南商丘人，出生于高辛（今河南省商丘市睢阳区高辛镇），后被帝喾封于商丘主管火正，后世尊称其为“阏伯”、“火神”，五帝之一帝喾之子、帝尧的异母弟，生母为简狄。[1-3] 
尧称帝时閼伯官为司徒，后被封为契玄王。相传为帝喾后妃简狄吞玄鸟之卵而生。《左传》载：“陶唐氏之火正契居商丘，祀大火，而火纪时焉。相土因之，故商主大火。”他是商族部落的祖先，也是商朝开国君主商汤的先祖。[1] 
公元前2400年的尧舜时代，契发明了以火纪时的历法，在管火的同时筑造阏伯台观察星辰，以此为依据测定一年的自然变化和年成的好坏，为中国古老的天文学作出了重要贡献。契在他的居住地“商”（今商丘）做火正，呕心沥血，深受人民的爱戴，故中国民间尊他为“火神”。契死后葬于商丘阏伯台下，由于契的封号为“商”，他的墓冢也被称为“商丘”，即今商丘市的由来。
契时，商族正进入父系氏族社会阶段，距阶级分化和商朝的建立还有一段时间。因此，在夏朝统治时期，刚刚兴起的商族仅仅是夏朝在西方的一个附庸。从契至汤的14世中，虽然商族人在黄河中下游广阔的平原上频频迁徙达八次之多，但每次迁徙后都又回到了商丘。由此可见，商族由契至汤的14世都是以商丘为根据地，不断向外拓展而逐步发展起来的。公元前16世纪，商汤建都亳，这里成为商朝的第一国都。从商朝至今近4000年的悠悠岁月，商这块土地上，留下了许许多多灿烂与辉煌。
