卷一·第二章　星历左页的读法

Of the use of the Ephemeris.

论星历的用法。

The first line on the left-hand page, tels you, January hath 31. dayes.

左页第一行告诉你，一月有三十一天。

In the second line you find, The daily motions of the Planets and the Dragons head.

第二行你看到的是：诸行星与龙头的每日运行。

In the third line and over the character of ♄ you have M. D. M. signifying Meridionall, D. Descending; that is, ♄ hath Meridionall latitude, and is Descending.

第三行，在土星 ♄ 的符号上方，你看到两个缩写字母，一个表示「南方的」，一个表示「下降」；就是说，土星有南纬，并且正在下降。

In the next column you find M. D. and underneath ♃; that is, Jupiter hath South or Meridionall latitude, and is descending.

下一栏你看到同样这两个字母，下面是 ♃；就是说，木星有南纬，并且正在下降。

In the third column you find M. A. and under those letters ♂; that is, ♂ hath Meridionall latitude, and is ascending.

第三栏你看到表示「南」与「上升」的两个字母，字母下面是 ♂；就是说，火星有南纬，并且正在上升。

The ☉ hath never any latitude.

太阳 ☉ 从来没有纬度。

In the next column to the ☉ you find ♀ and then ☿, with the title of their latitude: Now if over any of the Planets you find S. A. or D. it tels you that Planet hath Septentrionall or North latitude, and is either ascending or descending, as the letters A. or D. do manifest.

太阳的下一栏你看到 ♀，再下一栏是 ☿，上面都标着各自纬度的名目：如果你在任何一颗行星上方看到表示「北」的字母，再加上表示「上升」或「下降」的字母，就是告诉你这颗行星有北纬，并且照那个字母所示，正在上升或下降。

In the fourth line you see ♄ ♃ ♂ ☉ ♀ ☿ ☽ ☊; now you must observe ever, the ☋ is in the opposite Signe and degree to the ☊, though he is never placed in the Ephemeris.

第四行你看到 ♄ ♃ ♂ ☉ ♀ ☿ ☽ ☊；这里你必须时时留意：龙尾 ☋ 总在与龙头 ☊ 相对的星座、相同的度数上，尽管星历里从来不列出它。

In the fifth line you have ♈ ♊ ♑ ♑ ♓ ♒ ♏ ♌: Over ♈ you have ♄, that is to acquaint you, that ♄ is in the Signe of ♈: Over ♊ you have ♃, viz. ♃ is in the Signe of ♊: And so over ♑ stands ♂: And so of all the rest one after another.

第五行是 ♈ ♊ ♑ ♑ ♓ ♒ ♏ ♌：♈ 上方是 ♄，这是告诉你土星在白羊座；♊ 上方是 ♃，即木星在双子座；同样，♑ 上方是 ♂；其余各星也都一个接一个这样读。

In the sixt line you have the figure 1. telling of you it's the first day of January, and so underneath it to the lower end, you have the day of the moneth.

第六行你看到数字一，告诉你这是一月一日；在它下面一直到页底，依次是该月的日期。

Next to the Figure one, you have the letter A, which is the letter of the day of the week; and if you run downe under that column, you see the great letter to be D, which is the Sunday or Dominicall letter of the yeer 1646.

数字一旁边是一个字母，这是星期的字母；顺着那一栏往下看，你会看到一个大写字母，那是一六四六年的星期日字母，也叫主日字母。

Over against the first day of January under the character of ♄ you find 27. 48. over those figures you see ♈; the meaning is, ♄ is the first day of January in 27. degrees and 48. minutes of ♈: now you must observe, sixty minutes make one degree, and that when any Planet hath passed thirty degrees in a Signe, he goeth orderly into the next; as out of ♈ into ♉, out of ♉ into ♊, &c.

对着一月一日这一行，在 ♄ 的符号下你看到二十七、四十八，数字上方是 ♈；意思是一月一日土星在白羊二十七度四十八分。这里你必须注意，六十分合一度；任何行星在一个星座里走过了三十度，就依次进入下一个星座，如从白羊进入金牛，从金牛进入双子，等等。

In the fourth column, over against the first of the moneth, you find 28 R 12, over them ♊, and over it ♃; that is, ♃ the first of January is in 28 degrees of ♊ and 12 minutes: The letter R. tels you that he is Retrograde; had you found Di. or D. it had told you he was then come to be Direct in motion. Of all these termes hereafter by themselves.

第四栏，对着该月一日，你看到二十八、表示逆行的字母、十二，数字上方是 ♊，再上方是 ♃；就是说，一月一日木星在双子二十八度十二分。那个字母告诉你，他正在逆行；假如你看到的是表示顺行的缩写，那就是告诉你，他那时已转为顺行。所有这些术语，后面再分别讲。

In the fifth column you find 10 5, over those figures ♑ ♂, viz. ♂ is the first of January in the tenth degree and five minutes of ♑.

第五栏你看到十、五，数字上方是 ♑ 和 ♂；即一月一日火星在摩羯十度五分。

And so by this order you find the ☉ to be in 21 degrees, and 34 minutes of ♑; and ♀ in 5 degr. 7 min. of ♓; ☿ in 5 degr. and 29 min. of ♒; the ☽ in 21 23 of ♏; ☊ in 12 deg. and 34 min. of ♌.

照这样的次序，你可查出太阳在摩羯二十一度三十四分；金星在双鱼五度七分；水星在水瓶五度二十九分；月亮在天蝎二十一度二十三分；龙头在狮子十二度三十四分。

So that you see on the left-hand page, there are ten severall columns; the first containing the day of the moneth; the second, the week-day letter; the third, the degree and minutes of ♄; the fourth containes the degrees and minutes ♃ is in; and so every column the like for the rest of the Planets.

由此可见，左页共有十栏：第一栏是该月的日期；第二栏是星期字母；第三栏是土星所在的度与分；第四栏是木星所在的度与分；其余各栏，诸行星也都一样。

Over against the tenth of January, under the column of the ☉, you find 0 ♒ 14 minutes, which onely sheweth you the ☉ to be that day at Noon, in 0 degrees and 14 minfutes of ♒, &c.

对着一月十日，在太阳那一栏下，你看到零、♒、十四分，这只是告诉你，那天正午太阳在水瓶零度十四分，等等。

In the lower end of the left-side page, after the 31 of January you find Lat. of Pla. that is, the Latitude of the Planets.

在左页的下端，一月三十一日之后，你看到「行星纬度」的缩写字样，也就是诸行星的纬度。

Under the letter C you find 1 10 20.

在一个字母下面，你看到一、十、二十。

Under the column of ♄ over against 1, you find 2 31; then continuing your eye, you have under ♃ 0 5; under ♂ 0 47; under ♀ 1 13; under ☿ 1 45. The meaning hereof is, that the first day of January ♄ hath 2 degr: and 31 min: of latitude; ♃ 0 degr: 5 min: ♂ 0 degr: 47 min: ♀ 1 degr: 13 min: ☿ 1 degr: 45 min: of latitude:

在土星那一栏、对着一的地方，你看到二、三十一；再顺着看过去，木星下是零、五；火星下是零、四十七；金星下是一、十三；水星下是一、四十五。这意思是：一月一日，土星有二度三十一分的纬度；木星零度五分；火星零度四十七分；金星一度十三分；水星一度四十五分的纬度。

To know whether it is North or South, cast your eye to the upper column, and you may see over the character of ♄ stands M. D. that is, Meridionall Descending, or South latitude; where you find S. it tels you the latitune is North; if you find A. the Planet is Ascending in his latitude; if D. then Descending.

要知道是北纬还是南纬，就把目光移到上面那一栏的顶上，你会看到土星符号上方是表示「南、下降」的两个字母，即南纬、下降，也就是南纬；凡见到表示「北」的字母，就是告诉你纬度在北；见到表示「上升」的字母，这颗行星在纬度上正在上升；见到表示「下降」的，就是在下降。
