Here is a contemporaneous control effort:<p><i>We prohibit under anathema that murderous art of crossbowmen and archers, which is hateful to God, to be employed against Christians and Catholics from now on.</i><p>Canon 29, 2nd Lateran Council, held 1139, under Pope Innocent II<p>The council also forbade &quot;jousts and tournaments&quot;.
Apparently the original text has not survived, so only 
secondary sources and translations are available,
some of which vary.<p>In any case, the prohibition appears to have been ineffective.
