Hello,<br/><br/>I read this on a site where you can download books in the public domain earlier today:<br/><br/><i>The Odyssey</i><br/><i>By Omer</i><br/><i>Circa 600 BC</i><br/><br/>I was wondering, can I also put 'circa' after the date – 600 BC circa? Do you also abbreviate it as 'ca.'– Ca. 600 BC?<br/><br/>Thank you<br/>H.
