Now, the way they used to count time was based on the phases of the moon, which, regularly and predictably, goes through a cycle, starting with a new moon, then to a full moon, and back again to the new moon.

嗯,他们往往通过月亮的相位来记录时间,相位的变化是有规律且可预测,这个周期以新月开始,接着是满月,再重新回到新月。

Now this cycle was then used to determine the length of their month.

它被用来他们日历里每个月的长度。

So, um, one lunar cycle was one Egyptian month, and about four of the months would constitute a season.

所以,按照这种算法,一整个月相变化构成一个完整的埃及月,四个埃及月构成一个季。

Now, 12 of these months was an approximately 354-day year.

这样的话,12个月构成了一个长度大约为354天的“年”。

So they had a 354-day agricultural calendar that was designed to help them determine when the Nile would inundate the land.

所以他们有354天的农业日历,帮助他们来决定什么时候,这个大陆什么时候被淹没。

Well, of course it had to be more complicated than that.

嗯,当然实际上,它比我们讲的要复杂。

The average amount of time between floodings wasn't actually 354 days.

两次淹没的时间间隔实际上不是354天。

I mean, although it varies, the average was clearly longer than 354 days.

我的意思是,虽然这个间隔会有所变化,但很清楚它比354天要长。

So how did they keep this short calendar in step with the actual flooding of the Nile?

这样的话,就产生了一个问题:他们是如何让这个短的日期与尼罗河的淹没保持一致呢。

Well, their astronomers had discovered that at a certain time of year the brightest star, Sirius, would disappear.

埃及人的天文学家发现,在一年的某些时间,最亮的行星,即天狼星将会从天空消失。

Actually, it'd be hidden in the glare of the Sun.

实际上,它是被太阳光的光亮给盖住了。

And then, a couple of months later, one morning in the eastern sky just before dawn, Sirius would reappear.

几个月之后的某一天的大清早晨,黎明之前东方,天狼星又会重新出现。

And it happened regularly, about every 365 days.

这个周期很有规律,长度大约为365天。

Even more significantly, the reappearance of Sirius would occur around the same time as the Nile's flooding.

更重要的是,天狼星的出现基本与尼罗河水涨潮同步,

And this annual event is called a heliacal rising.

所以每年的这个事件都被称作“偕日出”。

The heliacal rising was a fair indicator of when the Nile would flood.

偕日出能够很好地告诉我们尼罗河将在何时被淹没。
