In CQ 34 (1984), 457, on Lucan 4.664 indulsit castris, I wrote ‘Housman…explains “…inuitantibus ad desidiam”: read rather ad temeritatem’. Mr S. J. Heyworth has kindly pointed out to me that Housman in his corrected impression (1927) does in fact write temeritatem. I was myself (as was evidently TLL vii. i. 1252. 10ff.) using the first impression (1926), where H. has desidiam. It had not occurred to me that H. would so drastically alter an interpretation in a ‘Second impression (corrected)’.
