בָּרִאשׁוֹנָה הָיוּ מַשִּׂיאִין מַשּׂוּאוֹת. מִשֶּׁקִּלְקְלוּ הַכּוּתִים, הִתְקִינוּ שֶׁיְּהוּ שְׁלוּחִין יוֹצְאִין:
In the beginning, they would light beacons [to inform those at a distance that the month had been sanctified, and they did not have to hire messengers to send them to the exile to apprise them, for they would be apprised by the beacons.] When the Cuthites attempted to undermine (the institution of the New Moon) [and they, too, lit beacons at the wrong time, to deceive them], they ordained that messengers go out [For beth-din would light beacons only for a month which was sanctified on the thirtieth day; and if they did not light them on the eve of the thirtieth day, all knew that the month was full. And once beth-din intercalated the month and did not light beacons on the eve of the thirtieth day — and the Cuthites lit them in their hills and deceived the Jews in the exile into making the month defective (instead of full)].
Tosefta Rosh Hashanah (Lieberman)
Formerly it was customary to signal with beacons on the high mountain peaks: on the Mount of Olives, on Sartaba, on Agrippina, on the Tabor, on the Hauran and Bet Bilti. R. Shimon ben Elazar says: Also the mountains of Machaerus and Gadara and similar. When do you signal the month? [Answer:] On the night it was switched on. How [one should understand this] ? [Answer:] He fell on a Friday or Sabbath, one signals on Sunday because of it; when the month comes in its time, one signals for it; but if not, one does not signal for his sake. Because of all the months one signaled with signal fires. Said one: Before the sun , so he said nothing. [He said:] To the south of her, his words are valid. If one said: I saw him two ox sticks high, and if one said: three, then the testimony is valid. If one says three, and one says five, they are not taken together; but he is taken together with others [who make the same statement]. Says one I have seen him erect, and one says: I have seen him bent, so they are not taken together, but he is taken together with others [who make the same statement]. If he saw him half in the water, he said nothing; [he saw] him halfway through a cloud, he said nothing. [If he saw] him half through glass, he said nothing. R. Elazar ben R. Zadok says: If he is not seen in his time, the month is not sanctified; because heaven has it already sanctified. And likewise, R. Eleazar ben R. Zadok used to say: The messengers do not go to Syria until they have heard from the mouth of the court: Sanctified.
