Orbs in traditional astrology?

What are the orb differences in traditional astrology for different astrologers?

Not sure also if some like dorotheus consider that a trine happens when 2 planets are 4 signs distant, not necessarily within an angle of 120 deg, but could also be 140 deg.

Any idea? I find this subject rarely treated about in some old books.

Would be useful if you would reference which specific Dorotheus comment you refer to

In many of the Greco-Roman works, such as Dorotheus, Manilius, Paulinus Alexandrianus, and others, platik aspects (and conjunctions) the generally followed rule (similar to what we find in Vedic astrology to this day) In other words, conjunctions and aspects were by signs, not degrees between bodies: eg, both Mars and Venus anywhere in say Taurus = a conjunction; Moon anywhere in, say Libra, would be square to Jupiter if Jupiter were anywhere in Capricorn (or anywhere in Cancer) It was SIGN TO SIGN, and so the matter of orbs did not arise.
The body to body conjunction/aspect-by degrees approach only really started to develop toward the end of the Classical period; by the early Islamic transitional age platik sign to sign conjunctions/aspects, had fallen into disuse.
