《Tetrabiblos》Mode Of Consideration For Particular Constitutions Of The AtmosphereClaudius Ptolemy（Ashmand 英譯 1822）
In order to learn these qualities, it is necessary, in every quarter, to observe, as above directed, the new or full Moon which may happen before[103] the period of the Sun’s transit through either tropical or equinoctial point, whichever it may be; and to arrange the angles (as in the case of a nativity) according to the degree and hour at which the new or full Moon may be found to happen, in every latitude for which the consideration may be desired.
