Supplicatio in ancient Rome was a solemn thanksgiving or supplication to the gods decreed by the senate. All the temples were opened, and the statues of the gods placed in public upon couches (pulvinaria) to which the people offered up their thanksgivings and prayers.

  Usage

A Supplicatio was decreed for two different reasons:

As a thanksgiving, when a great victory had been gained. It was usually decreed as soon as official intelligence of the victory had been received by a letter from the general in command. The number of days during which it was to last was proportioned to the importance of the victory.

Sometimes it was decreed for only one day but more commonly for three or five days. A supplication of ten days was first decreed in honour of Pompey at the conclusion of the war with Mithridates and one of fifteen days after the victory over the Belgae by Caesar, an honour which Caesar himself says had never been granted to any one before.

Subsequently a supplicatio of twenty days was decreed after his conquest of Vercingetorix. From this time the senate seems to have frequently increased the number of days out of mere compliment to the general. We thus find mention of thanksgivings for forty days, fifty days and even sixty.

A supplicatio was usually regarded as a prelude to a triumph but it was not always followed by one, as Cato reminds Cicero, to whose honour a supplicatio had been decreed. This honour was conferred upon Cicero on account of his suppression of the conspiracy of Catiline, which had never been decreed to any one before in a civil capacity (togatus) as he frequently takes occasion to mention.

A Supplicatio, a solemn supplication and humiliation, was also decreed in times of public danger and distress and on account of prodigies to avert the anger of the gods.
