|Thursday by Walter Dendy Sadler (1880)|
Many of Sadler’s humorous paintings featured monks and monastic life. In his 1880 painting, Thursday, which is also known as 'Tomorrow will be Friday', he depicts a group of Franciscan monks fishing. These friars were forbidden to eat meat on Fridays, as a reminder that Friday was the day when Christ was crucified.The "no meat" Fridays are still in effect for Catholics these days, by the way, though it is often mistakenly thought that rule was dropped after Vatican II.
