2.10–3.1:
Mitto igitur ad te Trebatium atque ita mitto ut initio mea sponte, post autem invitatu tuo mittendum duxerim.
This puzzles me, and I cannot find a better translation than:
I send you Trabatium*, then, and in such a manner, that first I thought that he was to be sent on my initiative, but later on your invitation.
The part I don’t like is “in such a manner”.
I take that ita to be a preface to the following two purpose clauses; so, …"and these are the reasons why I am sending him, first because …, and moreover/second because …
Your first clause, viz., “…that first I thought that he was to be sent on my initiative…,” is a bit too wordy for idiomatic English.
I think the gist is more like: “first it was my will and, moreover, you invited him.” I don’t think your “later” is the right word here.
Maybe this // Ita forsit:
So I am sending Trebatius to you and I do so just as I, on my own bat, reckoned he ought to be sent to you from the start, despite/besides however being asked.
Maybe you saw this, Baker:
Fortassè hoc vidisti, Pistor:
I don’t see “first” and “second”. // Primo secundo verba exfugiunt.
I like it! However, consider the letter from the beginning and I believe you will change your translation. You do get the tone of Cicero quite nicely though.
Yes, I read it through, Baker, and I would say this now:
Ita, Pistor, eam perlegi et sic nunc vertam:
So I am sending Trebatius to you and that I do as I initially independently reckoned he ought to be sent to you, though afterwards I was asked.
