I am writing this note on Mr. G. W. Richardson's Actium (JRS xxvii, 1937, 153) for the sake of one general principle, drawing attention briefly to the main points.
First, Horace. Mr. Richardson says sinistrorsum will not fit my interpretation because it is ‘commonly assumed’ that Antony's centre was opposite the mouth of the Gulf. Horace wrote within a few days of the battle, and was in a position to know; suppose we keep to what he says, and forget all about ‘common assumptions.’ If he says sinistrorsum, he means that Antony's whole fleet was north of the Gulf. Antony came out in line ahead—he could not do otherwise through the narrow exit; he could turn either north or south, and Horace shows he turned north, i.e. to his right. When all his ships were out—he could not do it earlier—he changed to line abreast; the last ship out, now the last on his left, might still have been opposite the mouth of the Gulf, but the three squadrons of the centre and left, taken as a whole, were northward of it, and if they wanted to get back into the Gulf they would go sinistrorsum. It is simple enough, provided we follow the primary evidence. Mr. Richardson further seeks to get rid of Horace's reference to the desertion of Antony's fleet, or of part of it, by saying that it means ships fleeing from (or after) the battle. But puppes navium citae, as a long line of commentators have pointed out, can only mean backing water, i.e. going stern first; and I am sure no galley ever fled from a lost battle stern first.
