During the Frankfort period Busch published three self @-@ contained illustrated satires . Their anti @-@ clerical themes proved popular during the Kulturkampf . Busch 's satires typically did not address political questions , but exaggerated churcheyness , superstition and philistine double @-@ standards . This exaggeration made at least two of the works historically erroneous . The third illustrated satire , Father Filucius ( Pater Filucius ) , described by Busch as an " allegorical mayfly " , have greater historical context .
