The first communication of St. Mars to Louvois after his arrival at Exiles, which has been published, is dated December the 4th, 1681,[118] and relates to the sickness of his prisoners: and the next is a letter, dated March 11th, 1682, containing a similar detail to those already alluded to, of the precautions he took for the security and solitary confinement of his two prisoners. He begins, by intimating that he has again received a charge from Louvois to that effect, and that he continues to guard his two prisoners as severely and exactly as he has ever done, and as he did formerly “Messrs. Fouquet and Lauzun, who could not boast that they had either sent or received any news, while they were in confinement.” He adds, that the two prisoners can hear the people who pass along the road at the foot of their prison, but that they cannot be heard by any one; that, in the same way, they can see the people who are on the hill opposite their windows, but cannot themselves be seen, on account of the bars placed across their room; that there are two sentinels always watching them, and who have also orders to prevent the passengers stopping under their windows--and that his own room, being joined to the tower, and commanding a view of the sentinels, the latter are by this means always kept alert. That, in the inside of the tower, he has made a partition, which prevents the priest, who says mass, from seeing the prisoners, as well as the servants who bring their food--which is afterwards carried in to them by his lieutenant; who, together with himself, the confessor, and a physician from Pragelas, a town six leagues distant, are the only persons who speak to them; the physician only being allowed to do so in the presence of St. Mars himself. He adds, that equal precautions are taken with regard to their linen, and other necessaries.[119] From this period, we hear no more of St. Mars and his prisoners in the published documents, for above three years; his next communication to Louvois being dated Dec. 23d, 1685; in which he informs him that his prisoners are still ill, and in a course of medicine. By the expression _still_ being here used, it would seem as if their malady had been of considerable duration. He continues, “they are, however, perfectly tranquil.”[120] The mention of their present tranquillity is certainly an indication that their insanity had continued, at least at intervals. Shortly after this, the Jacobin[121] died. Matthioli continued ill; and St. Mars, also finding his own health failing him, he[122] became convinced that the air of Exiles was unwholesome, and petitioned in consequence for a change of government.[123] Lewis upon this appointed him, in 1687, to that of the Islands of St. Margaret and St. Honorat, on the coast of Provence, near Antibes, and ordered him, as before, to take Matthioli with him.
