The Jovialists and Thursday people
10.71 Thursday
"The earth and air will freeze a very great sea,"
When they will come to venerate Thursday:
"That which will be never was it so fair,"
From the four parts they will come to honor it.
10.73 Jovialist (People of the Thursday)
The present time together with the past
Will be judged by the great Joker:
"The world too late will be tired of him,"
And through the clergy oath-taker disloyal.
A6611 Jovial (Thursday), Thrace
The enemy so much to be feared to retire into Thrace,
Leaving cries, howls, and pillage desolated:
To leave noise on sea and land, religion murdered,
Jovial Ones put on the road, every sect to become angry
A6007 Sedition Shaved head , jovials (Thursday)
A long comet to wrong the Governor,
Hunger, burning fever, fire and reek of blood:
To all estates Jovial Ones in great honor,
Sedition by the Shaven ones, ignited.

H065 Jovialist (Thursday)
Their assaults will not all be in vain, and the place which was once the abode of Abraham will be assaulted by persons who hold the Jovialists in veneration. And this city of "Achem" will be surrounded and assailed on all sides by a most powerful force of warriors.
