The czarowitz, on the contrary, had married only in compliance with his father's orders, had never rebelled against him, nor raised an army, nor taken refuge in the dominions of an enemy, and returned to throw himself at his feet, upon the very first letter he received from him; for, as soon as Peter knew that his son had been at Vienna, and had afterwards retired to Tyrol, and from thence to Naples, which, at that time, belonged to the emperor, he dispatched Romanzoff, a captain of his guards, and the privy-counsellor Tolstoy, with a letter written with his own hand, and dated at Spa, the 21st of July, N. S. 1717. They found the prince at Naples, in the castle of St. Elme, and delivered to him his father's letter, which was as follows:--

'I now write to you for the last time, to acquaint you, that you must instantly comply with my orders, which will be communicated to you by Tolstoy and Romanzoff. If you obey, I give you my sacred word and promise, that I will not punish you; and that, if you will return home, I will love you more than ever; but, if you do not, I, as your father, and in virtue of the authority which God has given me over you, denounce against you my eternal curse; and, as your sovereign, declare to you, that I will find means to punish your disobedience, in which I trust God himself will assist me, and espouse the just cause of an injured parent and king.

'For the rest, remember that I have never laid any restraint upon you. Was I obliged to leave you at liberty to choose your way of life? Had I not the power in my own hands to oblige you to conform to my will? I had only to command, and make myself obeyed.'

The viceroy of Naples found it no difficult matter to persuade the czarowitz to return to his father. This is an incontestable proof that the emperor had no intention to enter into any engagements with the prince, that might give umbrage to his father. Alexis therefore returned with the envoys, bringing with him his mistress, Aphrosyne, who had been the companion of his elopement.

We may consider the czarowitz as an ill-advised young man, who had gone to Vienna and to Naples, instead of going to Copenhagen, agreeable to the orders of his father and sovereign. Had he been guilty of no other crime than this, which is common enough with young and giddy persons, it was certainly very excusable. The prince determined to return to his father, on the faith of his having taken God to witness, that he not only would pardon him, but that he would love him better than ever. But it appears by the instructions given to the two envoys who went to fetch him, and even by the czar's own letter, that his father required him to declare the persons who had been his counsellors, and also to fulfil the oath he had made of renouncing the succession.
