Did Justin Martyr believe Jesus was a "second God"?

In Justin Martyr's *Dialogue with Trypho* Chapter 56: > **Justin**: I shall attempt to persuade you, since you have understood the Scriptures, [of the truth] of what I say, that there is, and that there is said to be, another God and Lord subject to the Maker of all things. -[Dialogue with Trypho (Chapters 55-68)](https://www.newadvent.org/fathers/01285.htm) What does he mean by "there is said to be, another God and Lord subject..." I assumed before that Justin Martyr was a Monotheist but it almost seems like he is implying Jesus is a second God.
